I don't have much experience with true pocket guns, other than brief affairs with a Jennings J-22 *blush* and a Pheonix HP-22. I have had my chrome-slide Kel Tec P-32 for about two months now - it's been with me pretty much every day since I picked it up. I've only put about 200 rounds through it, but it has yet to jam. It's EXTREMELY light - most of the time I forget I have it with me. I have it with me right now at work - it fits really well in the oversized watch pocket of my UnionBay shorts, along with other carpenter type jeans and shorts. When I tuck my shirt in, I carry it behind my wallet in my back pocket. It's 90 degrees today - shorts and a t-shirt are standard attire, and it's as easy to carry and conceal as a pocket knife. I was thinking about getting NAA Guardian, but the Kel-Tec is MUCH lighter, flatter, half the trigger pull of a guardian, about 150$ cheaper, and carrys one more round. I absolutely love mine. No, the 32ACP isn't a .50AE, but at close range FMJ ammo should do an adequate job. The sights are pretty much useless, but it points REALLY well - like a Luger or a Glock. From 7 yards using both hands in a Weaver style grip, I can keep all eight shots in the head section of a shilouette target with semi-rapid fire. Rapid fire, especially with one hand, will open the group up a good bit, but you can still keep them all in center mass if you practice.
Needless to say, I'm totally pleased with my P-32. Other people's experiences vary - I've heard some guys on this board say they've had major probs with theirs. But mine is an absolute gem - I keep it loaded with 8 Fiocchi FMJs and won't hesitate to rely on it, but I don't totally expect to put a determined attacker down with it. My personal theory of defense with a "mousegun" is "empty the gun as fast as possible without missing, as close as possible, in the direction of your attacker, cranio-ocular area if you can, center mass otherwise - then run like hell or be prepared to do two things: duke it out or reload."
However, when the weather cools down and clothing becomes more of a neccesity, the 18-shot Glock 19 at home in the safe will
return to active duty.
