I don't know which type of small pistol the man was carrying, yet, I do know that you do not put your "pocket junk" in the same pocket as your piece, pocket holster or not!
"drop safe pistol", as i understand it, wihout an exposed hammer.(J-Frames!)
IMHO, the man, whether CHL APPROVED or not, was an idiot. And yes, he just might be the cause for that new clean "no guns" sticker on the door, now.
