First off even if you have it in a shoulder holster or on your hip unless you can see the trouble coming you probably won't have time to pull it. I had a friend that was carjacked and had a pistol on the seat beside him but he never even had time to pick it up. The guy walked up and put a gun to his head and pulled him out. I keep onein my truck in case I need it but don't carry it on me. Last weekend I had to pull it out because some guy was chasing another guy with a hammer and he ran towards me in the truck. He stopped as soon as he seen the gun. Though I seen it happening and had time to get it out before there was any problem.
