I would wager Kel-Tec's top-selling list right now probably goes something like this:
1. PMR-30
2. KSG
3. P3AT
4. PF9
5. PLR-16 / PLR-22
6. etc. etc. etc.
The PMR-30 and KSG are definitely on the top end because of the whole "it holds a whole lotta rounds" appeal, and their unique construction. The P32, sadly, is probably near or at the very bottom of the list because most folks don't give the P32 or the .32 ACP cartridge that it chambers much (if any) of the love or respect that it deserves for what they offer. Everyone wants bigger, flashier, higher-capacity stuffs, and the P32 is none of those things. What it is, however, is something small, thin, light, that holds enough rounds of a caliber that reliably goes bang and sends bullets deep enough into bad guys to reach their vital bits and stop them from doing bad things. It has a role, and it fulfills it very well, but it does it in a way that doesn't get a lot of attention. The P32 is sort of like a fork in a spork-loving world, I guess.
