i have a theory. the reason we shoot double taps today is because officers carrying double/single guns needed to practice the transition from double action to single action. no point firing 3 or 5 rounds. just two to complete the transition. what's the point? everybody in handguns shoots double taps. why? and is it the magic number or is it snake oil? some people might think that one good clean shot isn't good enough, better use two. which could be justification to practice always firing two shots. double tap practice could also be the justification for always firing twice. you can see this circle keeps going. some people might think two shots are enough, because it's just engrained during practice to fire two shots. should we practice drills with other combos? triple taps, draw fire once. body and armor drills with three on the body? does distance come into play? a twenty-five yard shot requires a pretty good recovery time for the second shot. a cadence of less than a second will almost always result in an errant second shot. i've been told that when an attacker is absolutely on top of you, "shoot him to the ground". it might take more than two. thoughts?
