Neat trick, fun to watch, but that's all it is. I wanna see this guy do it under pressure, with 6 zombies rushing him from 20 ft. Trick shooting is for carnivals, IMO.
Just carry a Glock type pistol the way it was designed to be carried, with a round chambered. If 1911 type, round chambered and safety on. If DA/SA, round chambered and decocked if decocker type, hammer down if safety-type.
