Keltec
I have the Kel-Tec P32, which is small and light enough to fit comfortably in a pocket holster, even in shorts. The P3AT is of similar size, but I have never shot one. My P32 had feed problems during the 'break-in' period described in the owners manual. After the first 150 rounds, its been trouble free. I prefer a single action auto, so I have recently switched to a Colt Mustang Pocketlite I found on gun broker. It is about the same size but a little heavier, the feel to me is closer to my 1911s. The Colts are hard to find, and the Kel-Tec is a fine pocket protector. My only complaint with the Kel-Tec is the initial trigger pull, but that is my preference to a single action vs double action.
