I've got a P232 and, given the weight of the gun, .380 is about as much as can be fired a lot without taking all the fun out of it.
I also, own a Kel Tec .380, which is considerably lighter than the P 232 and, although it's reliable for what it's intended for, it's not a fun gun to shoot, simply because the felt recoil just isn't that pleasant. Kel Tec also makes a 9mm pistol in super-small, which I've never fired, and I've got to believe that it, like the .380, is only good for saving your life but not much fun at the range.
OTOH, I also have a SIG 239 which has the weight to handle 9mm very comfortably. I can shoot it all day, and not tire of the recoil. So there are always compromises. But if I'm going to shoot 9mm or .45 ACP, I want enough weight to the gun to deal with it.
