I'm very much torn on this. I prefer the workings of a revolver, and am a bit more confident with them mechanically, but I just shoot my auto's better.
As of now, I have a Glock 36 (6+1 45acp) and a Taurus 651 (5 shot 357 snub) which I carry. I tend to rotate back and a forth a bit, but I'd say the auto gets carried more often.
Now if I ever get around to picking up a 3" revolver, such as the new 327's, it would likely find favor as my carry gun.
