For true, non printing and COMFORTABLE carry in a pocket, I have been more than pleased with my Kel Tec P3AT 380. I am not a big fan of the 3800 cartridge, but with Buffalo Bore +P+ ammo I get a chronographed 1125fps with thier 100gr HCFN bullet, and over 1200 with thier 90gr HP. I have four of the former, and three of the latter stacked, alternating, in my P3AT right now. For a real, POCKET gun I consider this to be a pretty decent option.
Most days, I am packing my 10mm full size 1911 or my 329PD 44 Magnum. But as dedicated as I am to 24/7/365 carry there ARE times when a pocket pistol really is the only real option for carry.
The next step up, but in my opinion just a hair too big for easy pocket carry, is Sherri's (asphaltangel) Kel Tec PF-9. Smallest, lightest and thinnest 9mm going as far as I know. Great trigger, super comfortable to pack, but it does not fit in my jeans pockets at all without showing.
Good luck in your search, I wish you lived close enough to come shoot our Kel Tec's. We really like them.
