Pocket carry?
A j-frame, preferably an AirLite 340 or AirWeight 642 if you are partial to revolvers.
The Kel-Tec P-32 and P3AT are BUGS, not primary defense pistols. You can make a case for the 9 mm P11 but it that is a whole different class of pistol--a double stack 9mm, albeit a small one. If you want the weight and bulk of a double stack 9, get the reliability that goes with it, and buy a Glock 26/27.
Now, back to a semi auto the size/weight of a j-frame?
Kahr PM9. Period.
Oh yeah, Kel-tec PF9..which means you'll wait Probably Forever 9mm...
