Para Carry .45, Glock G30 .45, Springfield Ultra Compact High Cap .45, S&W 442 .38 Special. All have been proven to be totally reliable. It all depends what time of year, how much weight I want, and what I'm wearing.
Mostly a Glock 26 in a Galco concealed belt holster.
Sometimes a SW 66 in a Galco Speed Master High Ride.
Occaisionally a Beretta Tom Cat in a pocket holster (Jacket).
The Beretta may not pack much of a punch, but I hardly know it's there.
