I love this topic almost as much as Power Stroke vs. Slide lock......For me, inside 15ft, an aggressive side step during the draw makes more sense than trying to beat a trigger finger. Outside 15 ft the advantage of the side step diminishes since the angle the opponent needs to correct is small. I believe in the whole OODA loop thing and have seen bad azz gangsters lockup when things don't go their way. You WILL move when a gun is pointed in your face, might as well incorporate that reaction into your training.
