Have one of the Kel Tecs in .32 and wanted to up caliber also, decided on the 9 m/m P-11 Kel Tec. It is larger but not enough so that it causes my any problems with pocket carry. Only real problem is the recoil and pinching. Put finger extender on mags. and trigger shoe on to bring it down from uncomfortable to shoot to just not much fun to shoot.
Well, the thread is like four years old now. This isn't even. Possibility, now. Have long since got rid of the 32. Evenntually got. Kahr pm9. Got rid of that earlier this year one week after buying my first shield.
