I carry one frequently, but carry a 1911 more just due to it being flatter....the .45 Colt shoots a heavier bullet at least as fast as an ACP round....the first shot is just as fast as anything out there...if you know what you're doing, the next four or five can be pretty fast, too, about as fast as you can recover from a .45 Colt round, anyhow....need to solve the problem with 5-6 shots, though....but, as Bill Jordan said, something along the lines of, "if you haven't solved your problem with six shots, what makes you think things are going to get better with another six?"
