The Houston Police Department has ordered approximately 1,200 officers to replace their SIG Sauer P320 service weapons following a lawsuit alleging the pistol’s potential for unintended discharges.
Under the new directive, officers have until the end of September to make the switch.
The decision follows a lawsuit filed by veteran HPD officer Richard Fernandez Jr., who alleges that his holstered P320 discharged without a trigger pull.
The $10 million lawsuit, filed against the pistol’s manufacturer, SIG Sauer, claims Fernandez now suffers permanent numbness in his foot as a result of the incident.
“I heard a pop, but it didn’t sound like a gunshot,” Fernandez recounted. “I looked down, saw a hole in my pant leg, and realized I was bleeding. My hand wasn’t anywhere near the gun.”
His legal team argues that SIG Sauer has long been aware of serious design flaws in the P320. The suit joins more than 100 similar claims filed nationwide since 2017, many alleging the pistols fired while holstered or after being dropped.
The P320 has a controversial track record with HPD. In 2017, tests done by HPD found the pistol can accidentally fire almost 10 percent of the time after being dropped.
I wonder if this was pre- or post-voluntary upgrade.
While it was adopted by the U.S. military in 2017 as the M17 and M18, the civilian version soon faced scrutiny following reports of “drop-fire” incidents. These concerns prompted SIG Sauer to launch a voluntary upgrade program in 2017 to address potential discharge risks.
Despite the upgrades, lawsuits have continued to emerge alleging that the P320 can still fire without the trigger being pulled.
A jury found the SIG P320 “defectively designed” in a Massachusetts police lawsuit last month.
Steve Crowder devoted a show to P320 problems, including collecting videos of uncommanded discharges:
Crowder shows four videos of police P320s going off in the holster with no one’s fingers anywhere near the trigger. In two of those instances an officer was shot. And those are just the instance where the discharge was actually captured on film, so it seems reasonable to assume that there are a whole lot more that weren’t filmed.
Crowder also notes a very significant change in the language of Sig’s denials: “Newest email. The P320 cannot, under any circumstances, discharge without the trigger first being moved to the rear. Cool. “Trigger pull” versus “moved to the rear.” You know that change had to have come straight from their legal department in a CYA memo.
Crowder also had on Brandon Herrera (who previously covered the issue) to talk about the P320:
Brandon Herrera: “ICE has released a report. Basically they were talking about all the accidental discharges that have happened with all of their service weapons. And you have multiple columns. One of them is which pistol it was. Vast majority were the P320s. Then in the other column whether or not that incident included injury. So they not only said that these things were going off, but there were multiple occasions where they were injuring people that were actively working for ICE.”
BH: “if if they admit there is a problem with the civilian side stuff, then they have to maybe go in and [do] a very expensive upgrade to all their their military contract [P320s].”
BH: “Hopefully this is a big enough deal with this airman unfortunately losing his life that Sig can no longer look the other way and pretend there isn’t a problem.”
Steve Crowder: “How do you think [Sig] scored such a big contract with at that point a relatively new pistol?
BH: “That’s an excellent question.” [long pause]
BH: “It seems like Sig has gotten a lot of these contracts. And the question is whether that was based on merit, or some other thing that I won’t say in a public setting.”
BH: “I’m frankly shocked I haven’t gotten a cease and deceased yet. A cease and desist yet. I think it might be coming soon because I think they’re at the point where they, especially this this most recent wave, they’re losing control of the narrative. Before it was easy to just say, ‘Oh, it’s a couple of grifters, you know, don’t pay any attention to them. Pay no attention to the man behind the curtain.’ But now, I mean, hell, it’s everybody. The the conversation is completely shifted. Very few people are defending Sig anymore on this.”
SC: “My hunch is because of the military doesn’t want to admit that they screwed up either.”
Off the topic of Sig, Herrera says he’s not eager to run for office again. “Running the first time was probably one of the worst nine-month experiences of my life. And I would love to not repeat that again, but at the same time, they’re not voting any better.”
At this point its hard to see Sig gets out of this jam short of completely withdrawing the P320 from the market. Their potential liability is huge, and replacing all military and police service arms may be ruinous, as, presumably, any sort of recall to fix the problem, even assuming that they could find a fix and provide a solution that works.

People keep using the 1980s Tylenol recall as a relevant example, and it’s a fair point. This is definitely one of those cases where pennies for a recall would’ve been way cheaper than years of pounding lawsuits.
While they should indeed have done the recall, the problem they’re having now is separate from the drop discharge problem, and seems to affect modern P320s that presumably incorporate any changes made after the initial “voluntary upgrade” was offered.
Maybe doing a recall on the initial problem would have bought them more goodwill to address the current problem, but that first change has not solved the current uncommanded discharge problem.
“It’s an allegation that has tons of empirical evidence behind it.”
I was previously given assurance by “10×21” that the P320.was 100% mechanically engineered, making its track record impervious to criticism. Videos of the police being shot by their own pistol.would seem to call into question his qualifications as an expert witness.
Guns are designed to be dangerous but should not capriciously imperil their handlers. This is a black mark on SIG’s record. Every effort should be made to discover what is producing these uncommanded discharges before any more innocent lives are lost.
“I was previously given assurance by “10×21” that the P320.was 100% mechanically engineered, making its track record impervious to criticism. Videos of the police being shot by their own pistol.would seem to call into question his qualifications as an expert witness.”
I purchased my first Glock pistol, a fairly rare Generation 1 Model 19, in a hospital room, in the 1980’s. The Sheriff’s Deputy from whom I purchased it had an “uncommanded discharge” in his holster and was in the hospital having his leg rebuilt as a result. He was absolutely convinced that the Glock pistol design was unsafe and responsible for his injury. His lawsuit against Glock had failed, in a much different legal environment. He probably would have won in today’s ‘jackpot justice’ legal environment.
I was never able to get that pistol to “uncommanded discharge”. Still have it. Don’t shoot it much these days due to its collector value, but I am convinced that the deputy inadvertently trapped something in the holster which “moved the trigger”. Probably his shirt hem. He was an undercover officer.
I have carried Glocks for over 35 years without incident. I am fastidious about inspecting my holster’s interior before inserting the pistol. I never throw or manhandle pistols in their holsters. I followed the common sense provisions of US Air Farce Manual 31-229 long before the Air Farce even wrote their manual.
These incidents are more common than you are led to believe by the corrupt trial lawyers whose ‘engineering analyses’ you endorse. Also, a large number of these incidents are actually suicides or self harm incidents, a point not considered in the F.E. Warren Air Force Base incident. You might want to examine where that victim was on December 4, 2024.
“Gunsite Academy, like SIG’s detractors in the legal sphere, have no competency in mechanical engineering, so they go with the flow.

Oh, look! Zimmerman has published remarks calling for the P250’s immediate discontinuation from. service:
“The time has come for every law enforcement agency in Florida to stop using the Sig Sauer P320 sidearm as fast as they can be replaced. This is not a matter to be debated in endless committees or subjected to slow bureaucratic review. This is an officer safety issue. This is a public safety problem. And the reasons for decisive action are both compelling and urgent.”–Tampa PBA General Counsel Danny Alvarez

As evidence of corrupt lawyers and inept engineers defaming your cherished pistol you offer your personal evidence of not having been shot to death by your P250. But the airman who was shot dead is no longer available to contradict your testimony.

Do not have a P.250. Have never mentioned the P.250. The P.250 is not the pistol being discussed here. Have not heard of any “uncommanded discharges” by P.250 pistols. The “P2590” is a figment of your disordered, bible thumping imagination.
Only purchased a P.320 a month ago to understand these claimed “uncommanded discharges”. The NOS 2019 manufacture P.320 I bought is the only Exeter SIG firearm I now own, but have since ordered a 10x25mm P.320 XTen and a 9x19mm P.365 to further my studies.
Don’t own any German SIGs, either. They tend to be left hander unfriendly. I do have a lot of Swiss SIGs, but only as a collector. These pistols have no similarities to the P.320, in any event.
“Probably his shirt hem. He was an undercover officer.”
“He musta stuck his shirt innit or sumpthin’ else becuz undercovrr.
Once more, your irreproachable mechanical engineering skills bring needed insight to a seemingly intractable problem.”
You are too young and ignorant of history to know that Glock was inundated in “uncommanded discharge” lawsuits when they introduced the Model 17 to the U.S. market in 1987. They embargoed civilian purchases for a while as they worked through the cascade of falsehoods spread by corrupt lawyers.
The only way a civilian could buy a Glock at the time was to purchase a used model from a LEO. Why I purchased my first in a hospital room.
SIG appears to be experiencing the Glock legal attack history redux.
“I purchased my first Glock pistol, a fairly rare Generation 1 Model 19, in a hospital room, in the 1980’s. The Sheriff’s Deputy from whom I purchased it had an “uncommanded discharge” in his holster and was in the hospital having his leg rebuilt as a result.
Was that on the same day you kissed Cindy Crawford right on her mouth?

Your reading comprehension is sad. Dan Zimmerman was quoting Tampa PBA General Counsel Danny Alvarez in an editorial ‘Florida must prioritize safety: The case for ending law enforcement use of the Sig Sauer P320 pistol.’ Zimmerman’s SNW post was titled ‘FL Police Union Official: It’s Time to Stop Using the SIG SAUER P320’. Just reading the title should have clued you in.
Dan Zimmerman is a thoroughly professional journalist and has gone to great pains to provide the SNW audience all sides of this controversy. He has made no claims to be a firearms engineer.
Attorney Alvarez probably knows even less about firearms engineering than you, if that is even possible.
“The “P2590” is a figment of your disordered, bible thumping imagination.”
Judging from your insipid rejoiner, you have a deep attachment to nominalism..
“Your reading comprehension is sad. Dan Zimmerman was quoting Tampa PBA General Counsel Danny Alvarez in an editorial ‘Florida must prioritize safety.”
Thanks for the hermeneutical.lesson, Captain Obvious.

Comrade Cartridge has no peer when it comes to mechanical engineering, logic, law, theology or hermeneutics. No wonder the Jesuits made him a votarie.

Read today’s CNN post by Haley Britzky:
“Airman charged in fatal firearm incident at Wyoming Air Force Base”
The slide wiggle discharge strongly suggests that this pistol has been misassembled (missing striker safety lock and/or spring). This cannot be proven, however, without disassembling and examining the specific pistol. Think this was the issue with the FBI BRF analysis of the MSP pistol, which was rumored to have been in a motorcycle accident.
The P.320 has a striker safety lock which prevents full travel of the striker until the trigger is pulled at least 2 mm. Full trigger pull length to stop is 2.5 mm to 3.0 mm, so the 2 mm pull safety domain is the majority of the trigger articulation. I have measured this on more than a dozen P.320s.
The holster insertion discharge occurred because this yokel connected the trigger to the slide stop with his wall board screw. When the slide stop wiped the holster interior, it actuated the trigger.
A much better YouTube video from “Thinking Man” is titled ‘Sig P320 accidental discharge tested in CNC machine.’ My only exception with this video is the author’s failure to use primed cartridge cases to distinguish between striker safety lock function and normal discharge function.
In both videos, the pistols appear to be very high mileage. This may be a SIG P.320 issue, but none of the click bait videos have addressed this issue.
“The “P2590” is a figment of your disordered, bible thumping imagination.”
Your co-religionists are doing their level best to aid the invasion of illegal immigrants.
“U.S.. Catholic Bishops are citing Nazis, slave catchers, and replacement babies as they try to slam President Donald Trump’s popular immigration policies.
The bishops are also urging open borders, parroting cheap-labor demands from business groups, and pretending that illegal migrants are not illegal.”
This leaves you with a difficult decision: do you defend the invasion by foreign nationals or is your time and effort better spent defending pedophile priests from prosecution?
Of course you can always opt for the trifecta: defend a flawed pistol, a sexuallt deviant priesthood and a criminally inclined cabal of bishops.
“U.S.. Catholic Bishops are citing Nazis, slave catchers, and replacement babies as they try to slam President Donald Trump’s popular immigration policies.
The bishops are also urging open borders, parroting cheap-labor demands from business groups, and pretending that illegal migrants are not illegal.”
Your memory gets worse with time. Repeating what I have told you at least twice:
The bishops here speak for the Latin Rite only. Not the other 23 rites of the Catholic Church.
My rite is exempt to the Holy See. We have no association with the Latin Rite bishops, here or elsewhere. None of the Greek Rites subscribe to the left wing foolishness of the Latin Rite clerics.
No one holds the Baptists responsible for the even more aggressive immigration policies of the Lutherans and Methodists. But they are all Protestants.
There is a very clear Catholic position on immigration, as stated in the Catechism of the Catholic Church. This applies to all rites, including the clerics of the Latin Rite in America:
“2241….Political authorities, for the sake of the common good for which they
are responsible, may make the exercise of the right to immigrate
subject to various juridical conditions, especially with regard to the
immigrants’ duties toward their country of adoption. Immigrants are
obliged to respect with gratitude the material and spiritual heritage of
the country that receives them, to obey its laws and to assist in carrying
civic burdens.”
Do your fellow bible thumpers have such a clear doctrine on the political control of immigration? They probably rely on individual clerics, creating the same turmoil now occurring in the Latin Rite.
Even though Brian McDonald can never hope to equal the importance and engineering achievements of Comrade Cartridge, there now exists a small glimmer of hope that the P320 may be redeemable:
“An engineer who once worked at SIG Sauer has devised a way to address an “incomplete and unsafe design” in the SIG P320 pistol, according to claims on an application for a U.S. patent. The application was filed in 2024 amid allegations that the pistol can fire without the trigger being pulled – a charge the company vehemently denies.
“The engineer, Brian McDonald, appears to have worked at SIG while the P320 was being developed. He is listed as the inventor on a 2024 patent application that now is assigned to Angled Spade Technologies LLC.”
“Do your fellow bible thumpers have such a clear doctrine on the political control of immigration?”
Romans Chapter 13 (in part): Let everyone be subject to the governing authorities, for there is no authority except that which God has established. The authorities that exist have been established by God. 2 Consequently, whoever rebels against the authority is rebelling against what God has instituted, and those who do so will bring judgment on themselves. 3 For rulers hold no terror for those who do right, but for those who do wrong. Do you want to be free from fear of the one in authority? Then do what is right and you will be commended. 4 For the one in authority is God’s servant for your good. But if you do wrong, be afraid, for rulers do not bear the sword for no reason. They are God’s servants, agents of wrath to bring punishment on the wrongdoer. 5 Therefore, it is necessary to submit to the authorities, not only because of possible punishment but also as a matter of conscience.

McDonald put just enough B.S. in his application to attract the attention of chuckleheads like you. USPTO will not approve McDonald’s application. Angled Spade Technologies is trolling for investors to rip off. This is an exercise in fraud.
You probably did not notice that it would only be applicable to the P.320 pistols with external manual safeties. You certainly did not notice that the McDonald design critically weakens the axle of the manual safety, promoting field failures.

The correct lede to this chapter, from the original Greek, is “Let every soul be subject to higher authorities. For there is no authority except from God and those who have been ordained by God.” Christians only owe submission to authorities ordained by G_d, a subtle point you missed.
As you have applied this to illegal immigration in America, it says you were beholden to the outrages of Drooling Joe and Mayorkas for the last four years.
1st disclosure: I own a Sig, and am extremely happy with it, but it’s their “C3” version of a 1911 CCO.
2nd disclosure: I do not own ANY striker-fired pistols, nor will I ever own anything that depends on the trigger (or a secondary “trigger” on the trigger) as a safety. I can see nothing but potential problems from holstering a pistol without an actual safety.
That being said, one thing that appears to be common in all of the videos of these “uncommanded discharges” is that looks as though pressure was being applied to the outside surface of all of the holsters involved. In the room with all of the police it appears that the other cop’s thigh was pressed up against the holster when it discharged. With the female officer in the parking lot it appeared that her enormous gear bag was actually banging against her side and holster when it discharged.
Anything in the holster that is between the trigger and the holster material, whether it’s a solid object or just enough pocket lint, will have the potential to keep the trigger in a fixed position as the firearm is inserted, effectively “moving the trigger backwards”. I can just as easily see this happening with pressure being applied to the outside of the holster as well, squeezing the holster until the trigger is moved.
All of these striker-fired pistols with the “safety blade” in the trigger are subject to this kind of failure. I’ll never own one. The trend towards this is much like what we will see down the road with weapon-mounted flashlights, which are now all the rage. We’re going to see badly-trained people sweeping entire rooms and neighborhoods with their muzzles as they flash their light around a room or a yard. Startle reflex alone will cause some negligent discharges if they see someone or something they weren’t expecting. Again, I’ll never mount a flashlight to a firearm; my Maglite is next to the nightstand that holds my quick-open gun safe. I can safely sweep a dark area with my pistol pointed in a safe direction.
The firearm and the holster that it’s carried in must be considered a system, and must work well and consistently together. Accidental discharges caused by a poorly designed system are simply unacceptable.
“McDonald put just enough B.S. in his application to attract the attention of chuckleheads like you.”
McDonald put in enough hours as a firearms engineer at SIG to qualify as an authority on the subject of P-320s.
You emphatically rejected the opinion of lawyers, journalists, training academies, military and police organizations because they lacked engineering expertise such as you yorself claim to possess. Yet when confronted by the testimony of a firearms engineer, you reject his claims based on his application for a patent.
It has been said that a fanatic is one who will not change his mind and cannot change the subject. You claim to be an authority on a large body of disparate subject matter but the truth is you are a fanatic.
Brian McDonald’s 2025 U.S. Patent Application 2025/0164203A1 – ‘Firearm safety with sear block’ is a shameless infringement of the 100 year old U.S. Patent 1,523,831 – ‘Automatic Pistol -Sear Safety’ of Franz Karpinski.
So now you are arguing as a “corrupt (patent) lawyer”?!
I thought lawyers had no subject jurisdiction where the P320 is concerned.
“Christians only owe submission to authorities ordained by G_d, a subtle point you missed.”
So it’s “Bible thumping for thee but not for me? Got it! Please forgive me for not recognizing your God-given authority to pass judgement on who or who is not an authority.
“As you have applied this to illegal immigration in America, it says you were beholden to the outrages of Drooling Joe and Mayorkas for the last four years.”
Post hoc, ergo proptor hoc fallacy.
There us a vast corpus of immigration law which Biden and Mayorkas were sworn to uphold.. In a Constitutional Republic, the Law is King.
Setting policy at variance to law is not what God ordains.
1st disclosure: I own a Sig, and am extremely happy with it, but it’s their “C3” version of a 1911 CCO.
The US Army already had what many consider to be the best general purpose sidearm in existence. They abandoned the 1911 because it was subject to negligent discharge when the hammer was clumsily lowered on a loaded chamber.
So they traded the risk of a negligent discharge for the likelihood of an uncommanded discharge. This is technological progress, evidently.
“The US Army already had what many consider to be the best general purpose sidearm in existence. They abandoned the 1911 because it was subject to negligent discharge when the hammer was clumsily lowered on a loaded chamber.

Hammer lowering discharges were uncommon in service usage of the Model 1911. They generally only occurred when the thumb underside was lubricated with oil or blood, and only on pistols which had the three dimensional checkering worn off the hammer by multiple refinish cycles.
The Model 1911 did not pass modern drop testing until the firing pin interrupter system was incorporated by Colt in their Series 80 version, 60 years after introduction. The U.S. military never adopted the Series 80 version and many other manufacturers never copied Colt’s firing pin interrupter system.
“Let everyone be subject to the governing authorities.”
This is a universal exhortation, not limited to Christians. Moreover, authority is not exclusively the province of civil authority. Under the law of Moses, parents could pronounce a death sentence on disobedient children.
BTW, what authority does Joe Biden have over me that I should fear to disobey him??
No proof is possible and none should be required. As evidence, I submit McDonald worked as a designer at Sig Sauer from 2011 to 2016. His work history with the company includes designing parts for pistols, creating fixtures for testing, and developing test plans to evaluate pistol function and durability.
Now prove that you are a mechanical engineer with a background in firearms design like McDonald’.
[…] had no intention of doing another Sig P320 post so soon after the last one, but the video was so informative on the (alleged) flaws, and so clear on things people seem to be […]

Angled Spade Technologies issued a clarifying statement on August 6th, on their P320 Fire Control Safety Patent [Application], which deletes their previous claims about Brian Mcdonald’s prior relationship with SIG Sauer. They probably got a cease and desist letter. They corrected a few other misstatements as well.
I you or Mcdonald had ever taken the sophomore class on strength of materials required of all engineering students, you would understand why digging a radius deep divot in a torsionally loaded shaft is a disaster waiting to happen. Cams are mounted on critical rotating shafts, not cut into them.

Don’t own any German SIGs, either. They tend to be left hander unfriendly. I do have a lot of Swiss SIGs, but only as a collector. These pistols have no similarities to the P.320, in any event.

Once more, your irreproachable mechanical engineering skills bring needed insight to a seemingly intractable problem.”
You are too young and ignorant of history to know that Glock was inundated in “uncommanded discharge” lawsuits when they introduced the Model 17 to the U.S. market in 1987. They embargoed civilian purchases for a while as they worked through the cascade of falsehoods spread by corrupt lawyers.
The only way a civilian could buy a Glock at the time was to purchase a used model from a LEO. Why I purchased my first in a hospital room.
SIG appears to be experiencing the Glock legal attack history redux.
“I purchased my first Glock pistol, a fairly rare Generation 1 Model 19, in a hospital room, in the 1980’s. The Sheriff’s Deputy from whom I purchased it had an “uncommanded discharge” in his holster and was in the hospital having his leg rebuilt as a result.
Was that on the same day you kissed Cindy Crawford right on her mouth?
“Oh, my mistake! That’s Dan Zimmerman from.Shooting Times. Evidently he too has become a soldier in the anti-gun army, First, Gunsite Academy and now Shooting Times editor Dan Zimmerman become pawns of the political Left!”
Your reading comprehension is sad. Dan Zimmerman was quoting Tampa PBA General Counsel Danny Alvarez in an editorial ‘Florida must prioritize safety: The case for ending law enforcement use of the Sig Sauer P320 pistol.’ Zimmerman’s SNW post was titled ‘FL Police Union Official: It’s Time to Stop Using the SIG SAUER P320’. Just reading the title should have clued you in.
Dan Zimmerman is a thoroughly professional journalist and has gone to great pains to provide the SNW audience all sides of this controversy. He has made no claims to be a firearms engineer.
Attorney Alvarez probably knows even less about firearms engineering than you, if that is even possible.
The Air Force says investigation has revealed some new facts, and charges of manslaughter and false official statements for someone.

Then get back to us with your next set of lies.
Would you both care to weigh in on https://www.youtube.com/watch?v=jOMQOtOQoPk ?
That video was covered here. And I expect to have another video om the subject this weekend…
“Would you both care to weigh in on https://www.youtube.com/watch?v=jOMQOtOQoPk ?”
The slide wiggle discharge strongly suggests that this pistol has been misassembled (missing striker safety lock and/or spring). This cannot be proven, however, without disassembling and examining the specific pistol. Think this was the issue with the FBI BRF analysis of the MSP pistol, which was rumored to have been in a motorcycle accident.
The P.320 has a striker safety lock which prevents full travel of the striker until the trigger is pulled at least 2 mm. Full trigger pull length to stop is 2.5 mm to 3.0 mm, so the 2 mm pull safety domain is the majority of the trigger articulation. I have measured this on more than a dozen P.320s.
The holster insertion discharge occurred because this yokel connected the trigger to the slide stop with his wall board screw. When the slide stop wiped the holster interior, it actuated the trigger.
A much better YouTube video from “Thinking Man” is titled ‘Sig P320 accidental discharge tested in CNC machine.’ My only exception with this video is the author’s failure to use primed cartridge cases to distinguish between striker safety lock function and normal discharge function.
In both videos, the pistols appear to be very high mileage. This may be a SIG P.320 issue, but none of the click bait videos have addressed this issue.
“The “P2590” is a figment of your disordered, bible thumping imagination.”
Your co-religionists are doing their level best to aid the invasion of illegal immigrants.
“U.S.. Catholic Bishops are citing Nazis, slave catchers, and replacement babies as they try to slam President Donald Trump’s popular immigration policies.
The bishops are also urging open borders, parroting cheap-labor demands from business groups, and pretending that illegal migrants are not illegal.”
This leaves you with a difficult decision: do you defend the invasion by foreign nationals or is your time and effort better spent defending pedophile priests from prosecution?
Of course you can always opt for the trifecta: defend a flawed pistol, a sexuallt deviant priesthood and a criminally inclined cabal of bishops.
“U.S.. Catholic Bishops are citing Nazis, slave catchers, and replacement babies as they try to slam President Donald Trump’s popular immigration policies.
The bishops are also urging open borders, parroting cheap-labor demands from business groups, and pretending that illegal migrants are not illegal.”
Your memory gets worse with time. Repeating what I have told you at least twice:
The bishops here speak for the Latin Rite only. Not the other 23 rites of the Catholic Church.
My rite is exempt to the Holy See. We have no association with the Latin Rite bishops, here or elsewhere. None of the Greek Rites subscribe to the left wing foolishness of the Latin Rite clerics.
No one holds the Baptists responsible for the even more aggressive immigration policies of the Lutherans and Methodists. But they are all Protestants.
There is a very clear Catholic position on immigration, as stated in the Catechism of the Catholic Church. This applies to all rites, including the clerics of the Latin Rite in America:
“2241….Political authorities, for the sake of the common good for which they
are responsible, may make the exercise of the right to immigrate
subject to various juridical conditions, especially with regard to the
immigrants’ duties toward their country of adoption. Immigrants are
obliged to respect with gratitude the material and spiritual heritage of
the country that receives them, to obey its laws and to assist in carrying
civic burdens.”
Do your fellow bible thumpers have such a clear doctrine on the political control of immigration? They probably rely on individual clerics, creating the same turmoil now occurring in the Latin Rite.
Even though Brian McDonald can never hope to equal the importance and engineering achievements of Comrade Cartridge, there now exists a small glimmer of hope that the P320 may be redeemable:
“An engineer who once worked at SIG Sauer has devised a way to address an “incomplete and unsafe design” in the SIG P320 pistol, according to claims on an application for a U.S. patent. The application was filed in 2024 amid allegations that the pistol can fire without the trigger being pulled – a charge the company vehemently denies.
“The engineer, Brian McDonald, appears to have worked at SIG while the P320 was being developed. He is listed as the inventor on a 2024 patent application that now is assigned to Angled Spade Technologies LLC.”

Romans Chapter 13 (in part): Let everyone be subject to the governing authorities, for there is no authority except that which God has established. The authorities that exist have been established by God. 2 Consequently, whoever rebels against the authority is rebelling against what God has instituted, and those who do so will bring judgment on themselves. 3 For rulers hold no terror for those who do right, but for those who do wrong. Do you want to be free from fear of the one in authority? Then do what is right and you will be commended. 4 For the one in authority is God’s servant for your good. But if you do wrong, be afraid, for rulers do not bear the sword for no reason. They are God’s servants, agents of wrath to bring punishment on the wrongdoer. 5 Therefore, it is necessary to submit to the authorities, not only because of possible punishment but also as a matter of conscience.

McDonald put just enough B.S. in his application to attract the attention of chuckleheads like you. USPTO will not approve McDonald’s application. Angled Spade Technologies is trolling for investors to rip off. This is an exercise in fraud.
You probably did not notice that it would only be applicable to the P.320 pistols with external manual safeties. You certainly did not notice that the McDonald design critically weakens the axle of the manual safety, promoting field failures.

The correct lede to this chapter, from the original Greek, is “Let every soul be subject to higher authorities. For there is no authority except from God and those who have been ordained by God.” Christians only owe submission to authorities ordained by G_d, a subtle point you missed.
As you have applied this to illegal immigration in America, it says you were beholden to the outrages of Drooling Joe and Mayorkas for the last four years.
We Uniates think this is foolishness.
1st disclosure: I own a Sig, and am extremely happy with it, but it’s their “C3” version of a 1911 CCO.
2nd disclosure: I do not own ANY striker-fired pistols, nor will I ever own anything that depends on the trigger (or a secondary “trigger” on the trigger) as a safety. I can see nothing but potential problems from holstering a pistol without an actual safety.
That being said, one thing that appears to be common in all of the videos of these “uncommanded discharges” is that looks as though pressure was being applied to the outside surface of all of the holsters involved. In the room with all of the police it appears that the other cop’s thigh was pressed up against the holster when it discharged. With the female officer in the parking lot it appeared that her enormous gear bag was actually banging against her side and holster when it discharged.
Anything in the holster that is between the trigger and the holster material, whether it’s a solid object or just enough pocket lint, will have the potential to keep the trigger in a fixed position as the firearm is inserted, effectively “moving the trigger backwards”. I can just as easily see this happening with pressure being applied to the outside of the holster as well, squeezing the holster until the trigger is moved.
All of these striker-fired pistols with the “safety blade” in the trigger are subject to this kind of failure. I’ll never own one. The trend towards this is much like what we will see down the road with weapon-mounted flashlights, which are now all the rage. We’re going to see badly-trained people sweeping entire rooms and neighborhoods with their muzzles as they flash their light around a room or a yard. Startle reflex alone will cause some negligent discharges if they see someone or something they weren’t expecting. Again, I’ll never mount a flashlight to a firearm; my Maglite is next to the nightstand that holds my quick-open gun safe. I can safely sweep a dark area with my pistol pointed in a safe direction.
The firearm and the holster that it’s carried in must be considered a system, and must work well and consistently together. Accidental discharges caused by a poorly designed system are simply unacceptable.
“McDonald put just enough B.S. in his application to attract the attention of chuckleheads like you.”
McDonald put in enough hours as a firearms engineer at SIG to qualify as an authority on the subject of P-320s.
You emphatically rejected the opinion of lawyers, journalists, training academies, military and police organizations because they lacked engineering expertise such as you yorself claim to possess. Yet when confronted by the testimony of a firearms engineer, you reject his claims based on his application for a patent.
It has been said that a fanatic is one who will not change his mind and cannot change the subject. You claim to be an authority on a large body of disparate subject matter but the truth is you are a fanatic.
Brian McDonald’s 2025 U.S. Patent Application 2025/0164203A1 – ‘Firearm safety with sear block’ is a shameless infringement of the 100 year old U.S. Patent 1,523,831 – ‘Automatic Pistol -Sear Safety’ of Franz Karpinski.
So now you are arguing as a “corrupt (patent) lawyer”?!
I thought lawyers had no subject jurisdiction where the P320 is concerned.
“Christians only owe submission to authorities ordained by G_d, a subtle point you missed.”
So it’s “Bible thumping for thee but not for me? Got it! Please forgive me for not recognizing your God-given authority to pass judgement on who or who is not an authority.
“As you have applied this to illegal immigration in America, it says you were beholden to the outrages of Drooling Joe and Mayorkas for the last four years.”
Post hoc, ergo proptor hoc fallacy.
There us a vast corpus of immigration law which Biden and Mayorkas were sworn to uphold.. In a Constitutional Republic, the Law is King.
Setting policy at variance to law is not what God ordains.
1st disclosure: I own a Sig, and am extremely happy with it, but it’s their “C3” version of a 1911 CCO.
The US Army already had what many consider to be the best general purpose sidearm in existence. They abandoned the 1911 because it was subject to negligent discharge when the hammer was clumsily lowered on a loaded chamber.
So they traded the risk of a negligent discharge for the likelihood of an uncommanded discharge. This is technological progress, evidently.
Anybody can file a patent application, but you will only receive a patent for something novel. Not a reprise of something patented 100 years ago.
No lawyer is named on U.S. Patent Application 2025/0164203A1, so McDonald probably filed it himself without a lawyer or a search of prior art.
“The US Army already had what many consider to be the best general purpose sidearm in existence. They abandoned the 1911 because it was subject to negligent discharge when the hammer was clumsily lowered on a loaded chamber.

Hammer lowering discharges were uncommon in service usage of the Model 1911. They generally only occurred when the thumb underside was lubricated with oil or blood, and only on pistols which had the three dimensional checkering worn off the hammer by multiple refinish cycles.
The Model 1911 did not pass modern drop testing until the firing pin interrupter system was incorporated by Colt in their Series 80 version, 60 years after introduction. The U.S. military never adopted the Series 80 version and many other manufacturers never copied Colt’s firing pin interrupter system.
Post hoc, ergo proptor hoc fallacy does not apply.
You verbosely claimed that good Christians were bound to follow authorities like Drooling Joe and Mayorkas. I took exception to that.
“McDonald put in enough hours as a firearms engineer at SIG to qualify as an authority on the subject of P-320s.”
Prove it.
“Let everyone be subject to the governing authorities.”
This is a universal exhortation, not limited to Christians. Moreover, authority is not exclusively the province of civil authority. Under the law of Moses, parents could pronounce a death sentence on disobedient children.
BTW, what authority does Joe Biden have over me that I should fear to disobey him??
Prove it.
No proof is possible and none should be required. As evidence, I submit McDonald worked as a designer at Sig Sauer from 2011 to 2016. His work history with the company includes designing parts for pistols, creating fixtures for testing, and developing test plans to evaluate pistol function and durability.
Now prove that you are a mechanical engineer with a background in firearms design like McDonald’.

Angled Spade Technologies issued a clarifying statement on August 6th, on their P320 Fire Control Safety Patent [Application], which deletes their previous claims about Brian Mcdonald’s prior relationship with SIG Sauer. They probably got a cease and desist letter. They corrected a few other misstatements as well.
I you or Mcdonald had ever taken the sophomore class on strength of materials required of all engineering students, you would understand why digging a radius deep divot in a torsionally loaded shaft is a disaster waiting to happen. Cams are mounted on critical rotating shafts, not cut into them.
