I've actually been thinking about getting a Kel-Tec P32. I've heard mixed reviews about the P3AT over other 380s, but the P32 seems pretty solid from what I've read. Reasons are: smaller, lighter, and increased capacity compared to my Ruger LCP.
I consider 9mm the minimum I would carry with JHP, so I carry FMJ in my LCP (penetration tests for .380 are only good when they fail to expand, so I might as well just go the route that doesn't expand AND is cheaper). Most people who disparage the .32 say that it's because you can do .380 JHP vs. .32 FMJ, I see .380 FMJ vs. .32 FMJ, and they're not that different.
