I used to view the UD thing with skepticism. Not anymore, my 2 320’s sit in the safe now.

Yup, 320 is a bad design IMO.  I own the same gun, X5 Legion.   It sits in the safe, I will never holster that gun again.  Its just not worth it.

There are far too many other pistols that do what the 320 does and most are better.  SIG is a crap company, I can afford to let my gun sit in the safe, but not all can and have to carry that POS daily.

Actually TXDPS adopted the Sig 320 in June 2018 (so coming up on 8 years).  Seems longer, but TXDPS (according to a number of Troopers I have asked) seem to really like the 320 and are not reporting having "incidents".

Sig really went all out with the 320.  Not many can claim a gun that works 125% of the time, it's not a flaw more like a feature.

Also I dont buy the "it was modded for USPSA trigger group" excuse. There are tons of 25 cent trigger job Glocks and garage buffed 1911's that seem to not get caught repeatedly on video with UC discharges.

I don't trust any striker-fired pistols.  The SIG Sauer P226 is widely regarded in military and law enforcement circles for having a respectable, long-term safety record, with no widespread reports of self-discharge or "uncommanded" firing in its decades of service, including its use as the Mk25 by U.S. Navy SEALs. Still, safety is always paramount.

They know this. It's the same 4-5 posters in every 320 thread. Even if they had a UC they would convince themselves they had put their finger on the trigger, something was in their holster, etc.

It's an overcomplicated design, with minimal engagement surfaces, using MIM parts made in a 3rd world country. SIGs own testing showed a 30% striker block failure rate. That alone should tell you to buy something else.

Nope, because it locks trigger, not the sear.  The search slipping off striker tab is what's happening in the uncommanded discharges.....along with the striker safety sticking in slide and not functioning because of its peculiar and odd spring system.  Completely disregard that the sig365 is 100% different mechanically and doesn't seem to have holster pops.

Incredible chain of events / Swiss cheese holes lining up happens in complex systems.  Hidden states or non-considered state transition initiators and race conditions are dynamic behaviors that don’t often show up in static tolerance analysis, prototypes, or low population / short production run models. The fact there are a bunch of P320 units in service means a very low probability event gets a lot of ‘draws’ to hit the winning (losing) combination.  Between that and confounding noise (actual shooter error) I don’t think there will ever be a solid answer. But markets don’t need solid info to make decisions on the margin.

When the last agency I worked for traded in their Gen 3 Glock 22s we had several new ones sitting in the armory that were never issued.   They let the deputies purchase their issued weapons for $250, if they wanted to keep them.

I've owned numerous P320s over the years.  Never had a problem but I also never carried one other than for a range toy and desert plinker.  I sold them off over the last year.  Not so much because I didn't trust them but because I'm downsizing.

At this point I have to question why anyone would buy a 320 other than for a flux. We have so many good affordable options for handguns today. There are multiple options available for a striker fired polymer pistol that don't have recent recurring reports of just going off.

Want a really nice trigger: Walther
Want something the police carry: M&P or Glock
Want to be a Turk: Canik
Want to be a hipster: CZ
Want something cheaper: Ruger
Want to spend more: HK
Want to buy a Sig?: P365
Want to have others judge you: Springfield Armory
Want a gun that sorta kinda works: FN
Want a gun from a company you forgot exists?: Steyr
Want a gun from the oldest gun company in the world: Beretta

I mean just look at that list and I know there are ones I left off.
With so many options available. Just avoid the one with the potential problem.

Competition holsters commonly ride at a position and angle that is somewhat different than a typical carry holster. Incredible that it must have happened with his leg completely straight, otherwise he'd be missing part of his knee or thigh.
