I mean a partially tensioned striker is stil capable of detonating a primer, especially if the primer is fairly soft. If they didn't, Glocks wouldn't need a firing pin block. That's not really a safety benefit there. Only benefit you get is a slightly longer and heavier trigger pull than a really short single action trigger like a 1911, but even 1911s won't shoot without pulling the trigger (with Series 80 components even preventing the muzzle down slamfire).

The issue is the video doesn't have any obvious infractions, and I guarantee if a P320 was in that video, everyone would still be spreading it around. It certainly could be something in the holster, but seems like the guy looked at his holster and didn't recklessly shove the gun in, not did it go off when he initially holstered it and only discharged when he bent over. I know Sig doesn't get the benefit of the doubt that other gun companies do because of the genuine safety issue in the passt, but that video does show that just because a gun goes off in a holster doesn't necessarily mean it's the gun that's at fault.

That's why I want to see the guns replicate their incidents in a lab controlled environment. That was done with the drop safety issue and everyone figured out how and why these guns fired when dropped. But thus far, the "discharging in holsters" phenomenon hasn't had that yet.
