My normal, everyday gun is a SiG P220 .45. It's one of the originals, w/out the rebounding hammer. I know it's kind of old school, but I can still out shoot most of the Virginia State Police with it.

It's much easier to shoot than their .357 SiG's, and carries rounds that pack every bit as good a whallop as theirs.
I have other guns, too. I guess the second favourite is a Smith & Wesson 642. Lightweight .38, hammerless. Excellent carry gun, but accurate only at close range. If you carry it with Treasury load, it's an effective deterrent, if a little violent to shoot. LOL...
