I mentioned common thread in which there are 2: Sig P320s and LEOs.
I am not casting blame on either, merely pointing out the obvious.

Indeed, that was my point in the comment you quoted. I.e., it is odd that it seems to be or has been 80 +( according to the link) P320 ND or unintentional discharges. A comment in the link raises an interesting question:
“If you were an LEO who just had a desk pop with your P320, would you:
A) Report yourself for a Negligent Discharge,
B) Look for the guy in the grassy knoll, or
C) Blame that notorious Sig P320?”

Perhaps “C” is the correct answer when one considers the number of (80+) unintentional discharges with the P320 which intuitively leads one to think about the common thread.

“The strange part is that it seems to be happening to multiple Sig P320s. ”

Nothing strange about that at all. The P320 design is fundamentally to blame. They deviated from the industry standard by eliminating the trigger safety. Notice you never see this kind of thing happening with their own P365, right?

Here’s perhaps the most powerful example:
h ttps://www.reddit.com/r/SigSauer/comments/1j3ozj4/is_the_p320_actually_something_to_be_worried_about/

(If that link doesn’t work, just search the tweet from John Spears about the Orion Training Group not allowing P320s anymore.) The situation was a lifetime LEO and head firearms instructor. He pulled his holster out from its appendix position, and the UNTOUCHED P320 inside it fired and shot him in the femoral artery.

The gun was still in its holster and it fired! He never touched the P320 itself, he was removing the holster with the gun still in it. Has absolutely nothing to do with cops carrying too much junk, because if it did we’d see an equal number of reports from Glock, M&P, and XD cops shooting themselves, and they don’t. It’s only ever the P320. And that makes perfect sense when you consider that they deviated from the industry standard and did away with the trigger safety.

This isn’t a SIG problem, it’s not a negligence problem, it’s not a cop problem. It’s a P320 problem, full stop.

The strange part is that it seems to be happening to multiple Sig P320s. Plus, a proper holster would go far in eliminating these phenomenons.

Thanks for proving my point. Yes, 1911s and the rest don’t have trigger safeties, but they do have manual safeties, and the 1911 at least has a grip safety. Every case I’ve seen where the P320 has fired, would have been prevented by a grip safety. Even then, nobody carries a 1911 “cocked and unlocked”, because that would be stupid. But the P320 is exactly that — it’s cocked and unlocked. And it doesn’t even have a grip safety, so any trigger movement at all causes a bang. Glocks don’t fire under those same scenarios because they have a trigger safety. XDs have grip safeties. M&Ps have trigger safeties. Every manufacturer has at least a trigger or grip safety, except one… the Sig P320.

Returning to the more specific case: every cop gun out there has a trigger safety, except one: the P320. And the wave of accidental/negligent discharges are all about the P320. Coincidence? Or blindingly obvious? I vote the latter.

As for raw negligence, cops didn’t suddenly become negligent with the P320. Those same cops have carried M&Ps, XDs, Glocks, all sorts of things, and they haven’t been plagued with the rate of self-fired discharges like they have with the P320. Negligence level is almost unquestionably the same, but now cops are getting shot when their hands are nowhere near the gun. What changed? The P320 changed. It did away with an industry-wide standard practice of having the trigger safety. And now, all of a sudden, cops are getting shot left and right. It’s obvious.

That’s why departments are getting rid of them. They can train their officers, but they can’t control their officers, and the absolute fact of the matter is that a P320 will fire in circumstances where a Glock won’t, an XD won’t, an M&P won’t, and on and on and on.

SIG blew it. And they will never own up to it. When TTAG showed a P320 firing when it was dropped, SIG’s response was “our pistols are drop safe.” They’re as bad as Gavin Newsome. They won’t recall them, they won’t address the issue, the only thing users can hope for is that SIG will issue another “voluntary upgrade” program and start installing trigger safeties.

Neither do 1911s, hi-powers, and a whole list of other semi-autos. They have external safeties, but it’s not uncommon for them to be bumped to off by fingers and other things while holstering and drawing, or in the course of daily activities while on the hip. 99% of these NDs are just that. Negligence

Having worked in the public sector I can say without exaggeration that the moment a vendor realizes you’re paying with taxpayer dollars the prices of everything triple. At least.
It’s blatant theft of your tax dollars and very, very, very few people involved care. Most everyone involved just blindly cuts checks.

The people jacking up the prices to bilk the taxpayers and the government employees unquestioningly cutting the checks all need to go to prison.
