I think everyone will ultimately have their perspective on this one. I can’t recall having seen “lots” of videos with them simply going off with absolutely nothing happening in an appropriate holster, and I think *everyone* would love to see a clear and unequivocal video showing that to put it to bed.
To your question as to what can be done to help, Sig Armorer has released their “C.O.P.” Kit, which includes their disconnector. That thing is very sensitive to it being out of battery, and it most definitely causes a dead trigger unless very locked up. Everything else in the kit just helps, such as the +20% sear springs and the safety lever support spring. If you’d rather do something than nothing. I’ve got them in all of my P320s since why not.

And the Gray Guns trigger can only help more. Along with running a manual safety model, or installing one.
Historically, Glock probably has more uncommanded incidents over time than Sig does (or even exploding models) but has the benefit of having been around so long that the internet wasn’t such a hotbed back then. But that’s a whole different can of worms that I don’t intend to open, lol. Trying to keep this one on topic with my last above sentence.
Maybe this one needs its own thread, and is definitely off topic, but pretty sure this one won’t ever go off unintentionally. Arguably even intentionally, har har har.
