I like so many of mine, that I carry quite a few different ones. The Most often carried lately, is a Model 65 Smith that I had some extra worke done on. I also tote the 1911s, a couple of Browning HP, in 9mm or .40 S&W. Another 9mm I like is the little CZ 75D PCR. I rotate through several different Taurus CH 85, and Smith J frames, in two or three inch. My Mountain guns, in .44 mag and .45 Colt get carry time, as well as some of my 6 inch N frame Smiths.
I shoot them all often, each rides in good quality leather, and I feel absolutly comfortable with any one of them. .38 Special is the low side of what cartridge I will use though. I used to carry a Colt Pony Pocketlite, but every time I had even the remotest hint that it would be needed, I got a sinking feeling in my gut, that I had picked the wrong carry gun that day. I got rid of it.
