P320 spontaneous discharge
A friend sent me this link about some civil lawsuits against Sig regarding their P320. Both lawsuits involve former LEOs who got shot in the leg (i.e., what some ppl like to refer to as 'Glock leg'). It's likely that important details are missing, but as far as one can glean from the article, both P320s fired w/o being touched.

Drop-safety failure is one thing, but discharging w/o any impetus? The hypothetical, "The gun went off on its own," scenario? Confused

I have 4 320's. None have every spontaneously discharged. In fact, I have many, many handguns and none have ever discharged without me pulling the trigger. I supposed anything is possible. But it's interesting this never happens at the range, or when they are pointing the gun at a bad guy, or when it's in a safe.

Somebody local shot himself in the butt with a 365. He was bolstering it. He doesn’t blame it on spontaneous discharge. Says something had to have hit the trigger. He is LEO.

Quite simply, this is not credible and not believable.

Don’t they have a firing pin block like almost every other modern pistol? So that would mean both a sear AND the FPBS would have both have to have failed??? Seems like this would be a lottery winning turn of events.

Am I wrong??

Also am I the only one picturing count chockula and Frankenberry as partners in police uniforms?

Every single gun made will spontaneously fire when someone or something depresses the trigger. Or so I’m told.

I worked investigations of a couple negligent discharge incidents with service firearms where the gun reportedly "just went off". Examination of the firearms proved it was not possible without the trigger being pulled in some manner. There are some cheap junk firearms where this is possible but not with modern service guns in good working order.

Ok, if you have to nitpick Big Grin

Every gun made will BY DESIGN spontaneously fire when someone or something depresses the trigger, barring faulty ammunition, unadvisable alterations, or damaged or missing parts, etc.

Point is, the gun didn’t go off on its own in the above mentioned scenario.

A couple of thoughts on this. I have seen an increase of P320s at IDPA matches. So, guys using P320s in and out of holsters all day and shooting hundreds of rounds with no unintentional discharges. These are "gun people" and they are using proper holsters and such. The P320 does, in my opinion, have a shorter trigger engagement/release compared to other striker fired guns like Glock. When my PD switched from P229/239 to G22/G23 I found one of my guys carrying his G22 stuffed into a leather holster made for his P239, unable to snap the thumb break. The P320 doesn't have a trigger dingus and if it was a P320 instead of a G22 in that holster maybe the P320 could AD where the G22 wouldn't.

In fact, there was a ND by a member here on the forum a few months ago that resulted from that very thing... officerdave tried to stuff his P320 into a non-P320 holster that was made for a Springfield XD, and blew off part of his finger in the process: https://sigforum.com/eve/forums...935/m/1160027954/p/1

That makes sense, but sure as heck wouldn't support the lawsuits. Dumbassery is not a manufacturing defect. Of course it "just went off", no one wants to admit they shot themselves in the ass.

I don't believe in guns going off by themselves. But this gun's striker is fully, or almost fully, cocked, is it not? If some weird chain or cascade failure happened to release it without the trigger being pulled, is there enough power to ignite the cartridge? Is such a thing possible? I just want to cover all the bases. (I do have one, a 9mm C, and like it very much. It is my "go-to.")

Yep. It’s not as if a hammer would have to spontaneously cock itself & release while the weapon sits motionless, as with a DA/SA while in decocked status.

No, but without an actual component failure (a broken piece would be found upon inspection), several other parts need to move spontaneously to simulate a trigger pull. Seems a bit unlikely.

If a firing pin is under spring pressure and could be released without pressing the trigger (as was evidently the case with the P320 prior to the “upgrade”) then of course a more or less spontaneous discharge could occur. That was also evidently the problem with the Remington model 700 rifles that discharged without their triggers being pulled. The question would be whether releasing the firing pin is possible without action of the trigger.

Depends on your definition of spontaneous. A Clintonesque answer.
