i can only speak for myself, but im not worried about accidentally shooting someone else, im worried about accidentally shooting me. Got a gun tucked in the small of your back, youre getting in and out of cars, you sitting down and getting back up out of chairs, youre scooting past someone or something and your back is hitting the wall or a door......its something else, not my finger, that worries me about a possible discharge.
With the proper holster that is properly designed for how you carry the firearm it is a non issue.
