There is a ton of great 1903 info in this thread.
I've got a 1903, and pocket carry it from time to time in a pocket holster I ordered from Simply Rugged. If my choice was either a P-32 or the 1903, I will choose the 1903 every time. Nice capacity, very easy to shoot well, and conceals nicely.
Some day, when I can no longer fire my current carry gun due to arthritis, lowered hand strength, etc., then my 1903 will be my primary carry gun.
