The guys who suggest you buy what you will actually carry are right.

My choice is the .22 S&W auto.

I have other weapons that I like, and they are great fun, but in general...I don’t carry them. Carry the .22LR loaded with CCI Stingers.

I agree with the CCI Stingers. My fave carry pistol is my old Beretta "Jaguar Plinker" Model 70, the same little pistol they used in the movie Sword of Gideon. I wouldn't want to face Dirty Harry with it, but it's small and comfortable.
