There is a phrase that was common a decade or so ago in the shooting world, “Glock Leg”. When the Glock was relatively new, and people hadn’t fully transitioned to kydex holsters, there were a bunch of negligent glock discharges into the the leg when holstering. There is a famous video of a glock going of in a holster as the owner bends over.
Glock is fundamentally safer than the 320 because it has a “worse” trigger. Longer, harder pull. Maybe the dingus helps too. But if the trigger gets pulled, it will still go off, even in a holster.
