I remembered a report from magnum research on this I attached bellow, I realize they are a Sig competitor but Magnum research makes very good weapons and I doubt they would have released the report if it was inaccurate and Sig could sue them at any moment.

The information is under section D. He doesn’t specifically address the reset itself but states once the trigger travels the initial fraction of a inch without firing the internal safeties are disabled, and the weapon can fire in this state from being dropped or jostled.
As it turns out in recent reports this is a problem the military is having as well. I k ow there were a large number of discharges when law enforcement went with Glocks back in the day but that was due to officers bad habits of having their finger on the trigger combined with the reduction of pull weight between a double action and a striker. I’ve never seen anything credible on a Glock going off in a holster, but I’ve seen a few videos now of p320 going off with an officer just getting out of the car. Sig keeps releasing explanations on the videos but honestly the more it happens Sig seems to be jumping through mental hoops trying to explain it. Some of the videos are obvious user error, and that woman that threw it in her purse was just unbelievably negligent, but there are now a number of videos that are very hard to dispute, and to keep saying it was improperly holstered just isn’t working anymore.
