maybe, and maybe I never considered open carry so I have not fully though through every situation. Im also pretty sure its far fetched someone coming up and cold clocking you at the coffee counter for your gun, but its for sure if you are open carrying and that does happen your gun is going away if you get knocked out for a few seconds. Ive been training for some time now and have seen people throw an off balanced punch that drops the opponent, all it has to do it land in the right spot. I know for me personally, I like the idea of being able to go hands on without exposing my pistol if need be. I have (thank god) never been in a situation I need to draw a pistol, but have been in many where I have had to talk my way out of a fight, or have to restraint someone and I much prefer not having a pistol showing.
But different strokes for different folks, Im just prefer good guys to have guns open or concealed whatever.
