As said above, the critical factor is training. During my 28 years of working for the Man I have carried a Model 27-3, a Model 627-0, a Model 686-3, various 1911's in .45 ACP, a Glock 21, 22, 23, and 27 (bug). I would feel pretty comfortable with any of them. But, Doug M. is right, if you are heading into harms way with time to prepare, grab your M-4.

One old timer who was a firearms instructor left me with this bit of advice; he said, "If you know you are going to get in a gunfight tomorrow, call in sick." He'd been in a few and didn't recommend the experience.
