Houston police officer sues gunmaker Sig Sauer after pistol allegedly fired without trigger pull. Sig

Apparently several agencies have pulled the S320 from service over failure of safeties causing AD. Agencies include USAF, ICE and SAPD.

My son, former MP in the Marine Corps, carried the SIG P320. He stated it's a dangerous piece of crap. I don't own any SIGs. I've always thought they made great weapons. Evidently, this one has some trigger design issues which have caused the company serious legal issues; and they have not been willing to recall this pistol.

Gun nuts have been on about this for several years. I do think this will drive down P320 prices, which at least is nice. The DoD procurement might become 'an issue' as well. Sig makes a lot of nice things and some of this is 'overblown' imho but it will get political if some DoD folks try to reverse long-term procurement plans.

One of our local cops got a settlement from Sig for an accidental discharge. The local force pulled all of them out of the force and switch to Glocks.

All the SIG stuff is amusing as they've had that rep for DECADES. Here is a REALLY old meme about it: pic.twitter.com/RGeHr6yMpZ

I like Sig's metal guns. P226, P228, P229 - all fantastic weapons. DA/SA ... truly gems of a gun and a testament to modern engineering.

I've never understood why Sig changed the formula and went to striker fired guns. There's plenty of those on the market - Sig's secret sauce was their metal frame DA/SA guns. I've never personally owned a Sig manufactured striker fired gun - I have Glocks and Springfields for that. But I love my P228

Beat out the Glock by $14 per unit for the current service pistol
Apparently. Tag was the only major difference between the two finalists. And apparently this issue which did not emerge in testing with the Sig.

Funny part is, as much grief as they gave the old M9 over the years, it's latest model actually performed about on par with the Sig and Glick but it wasn't allowed into the final competition.

The fad was the trigger group design, where the internal mechanism of the gun could be swapped between different models of frame. My guess is that this has an unanticipated drawback.

It hasn't been an issue for the P365 and Sig isn't the only manufacturer who has gone to fire control units (FCUs). It's pretty much the future of striker-fired pistols. It's something specific to the P320.

Yep. Same here on the P226. Excellent weapon. SIG has made lots of good guns. They messed up on the 320. They need to do damage control, step up and handle it like big boys and move on.
Don't know if their upper management will do it.
Hate to see a great manufacturer go down due to one bad gun.

The anti 2A and anti gun crowd or doing happy dances though!!!

This. Loved all their pistols with the de-cock feature. You can't get much safer. Walther learned that in WWII with their P38 and PPK.

This is the video posted on the Outdoor Board.

You do know an airmen was killed recently through a malfunction...

I have thousands of rounds through my glock 19x, the runner up, and have never had one single issue.

This isn't just a one-off issue. It's repeatable and recently took the life of an airman.

I've got a P220 in .45. I love that pistol.

Dude needs to keep his finger out of the trigger guard when manipulating that weapon.

Issue the feds a CZ P-10C instead of Glock 19 if taxpayers are footing the bill. Otherwise, they can buy whatever they want with their own money.

Awful for all those involved. I daily carry a 365 and it's been great and my Sig 1911 has been fantastic.

That may all be true but I have read various takes as to why Glock lost, but a hundred million bucks isn't chump change. I have no idea, and fully disclaim being a handgun expert.

I wonder what a 're-compete' would look like as it took the Army something like 5+ years to pick Sig. And, I've never met a single person who had anything nice to say about the M9's.

The outcome of the XM17 competition created controversy within the firearms industry. The entries from Glock and SIG Sauer were down-selected as the two finalists of the competition. Once down-selected, the two finalists are supposed to undergo a second phase of Production Verification Testing (PVT) which includes a 22,500-round endurance test as well as environmental testing. However, the XM17 contract was awarded to SIG Sauer before these tests could be carried out. Explicit reasoning for this is unknown, although it has been attributed in-part to SIG Sauer aggressively underbidding their cost per handgun.

What a soap opera.

Although I own a G19, never been much of a fan of the striker fired weapons. I much prefer a SA/DA platform, but the Sig226 just didn't 'fit right'. Settled on a FNP years ago, the carry options are great condition 1, 2 or 3. Not a great concealed carry option.

Sorry to hear Sig is having problems. Will be tough to fess up, but Sig armorers need to come up with a real good field fix- soon.

My brother was an armorer for a large Sherrif's department and they had an accidental discharge several years ago. At the time Sig had indicated it was a first time it had been reported. Then they had 2 more within a year and promptly switched back to Glock.

Big fan of the H&K US45 but the 9MM version P30 is also great just not a fan of 9MM for combat. H&K would be the way to go for the Armed Forces. Glock is already being used by certain groups in the service branches.

When I was in the Marines I carried a Kimber 45 - M45A1 CQBP. Then later we also got some Glock 19's for additional options if wanted a 9MM.

I don't own any Glocks, I just don't care for how they feel in my hand, but I'm with you on not caring for striker fired pistols. I also prefer the SA/DA hammer fired guns and all of my carry guns except for the P365X are SA/DA hammer fired pistols, which are almost impossible to find these days.

One reason I like H&K so much is they still make numerous SA/DA hammer fire pistols. I own five H&Ks and will probably get a few more eventually. I do have the VP9SK, which is striker fired. Won't carry it as it has no manual safety, but if I had to, I would never worry about it accidently going off.

And just for the record, I have no problem with Glock in terms of quality. I think they're good handguns and will tell people to always try one when they're looking to buy their first gun.

Is the 320 issue a problem after 2016? Curious because I read recently that it was addressed in 2016

From Google AI

" Sig Sauer has addressed the safety issue related to the P320 pistol. Specifically, they implemented a voluntary upgrade program to modify the early versions of the pistol that were susceptible to accidental discharge when dropped. This program involved replacing the trigger with a lighter one and making adjustments to the sear.
Here's a more detailed explanation:
The Issue:
Early P320 models, particularly those with a thick curved trigger, were found to have a drop safety issue. In certain drop scenarios, the inertia of the trigger could overcome the internal safety mechanisms and cause the gun to fire.
The Fix:
Sig Sauer's voluntary upgrade program addressed this by:
Replacing the trigger with a lighter, thinner version.
Making adjustments to the sear.
Adding an out-of-battery disconnector.
Voluntary Upgrade:
Sig Sauer offered this upgrade free of charge to owners of the affected pistols.
Current Status:
P320s manufactured after the upgrade are considered to meet or exceed all safety standards. The company maintains that the current P320 design is safe and cannot fire without a trigger pull. "

I love my P10F.

The P320 that killed the airman was in a holster sitting on a table when it discharged. The video above demonstrates it well.

Man, there are a ton of these out there in the military and law enforcement. Not a comforting thought.
