Hey, don't knock a KelTec until you've tried one, they're dead-nuts reliable despit feeling like they're mostly made out of air and a little plastic. That looks like the .32 acp model, somewhere out there on the Net there's a Keltec forum where several members have shot thousands and thousands of round through a P3AT (which isn't much larger) without replacing anything but the nylon slide stop pin now and then and occasionally the recoil spring, and even then not because they failed but because the owners thought those parts looked or felt too worn. If they didn't have such terrible triggers they'd be a lot more popular. They have decent sights for that type of gun, which I consider a strictly close-range and/or backup pistol.
With new powders and much improved bullets, today's .380 is nearly equal (as far as "in a fight") to the typical 9mm round 20 years ago, and those worked pretty well for the caliber. Of course, if you're going to shoot ball, you're either carrying a .25acp or you're severely hampering your ability to stop an aggressor.
