Hoping to add additional information to the conversation for each of us to independently consider whether all information is available when assessing how reliable the dude is in the video where he says his sig just blasted him while resting in his holster.
Was his Sig one of those with the 'old' (and clearly flawed) design? Did he submit his through the upgrade process? Did someone note he was using a modified holster... if that is the case, such a factor changes the matter for any other responsible gun user who follows the rules of prudent care and handling, including storage, especially in a holster at condition 1.
I've attached a diagram from Sig which identifies their upgrade/design change which Sig feels mitigates the risk. I'm no engineer nor gunsmith so unqualified to opine as to whether this design change is good enough. I do own three P320s, and 2 P365s. My 320s are all post 2017 so don't require the 'upgrade' and I feel fine carrying them in condition 1. This is my choice as it is yours to avoid them.
ETA: Saved before attaching the diagram. Morning Derp.
