alamo - what's wrong with 180gr ammo? That's been my favorite load(besides Hydrashocks).
I must admit that the accuracy of this little gun is amazing, although my wrist hurts after shooting it. I'm beginning to love .40's, though. Just got a Ruger P94 to keep me Kel-Tec company. Try stacking them up... Everything lines up - the grip, trigger... Even the magazines are very similar to the point that the Ruger mag would probably work in the Kel-Tec if you cut notches in the side.
I am a little sad about giving up my P-32... But I'm planning on getting another one, along with a P-11 and maybe a Sub-2000.
