I don't see much difference in .380 vs .32 acp ammo price. .32 trends a little cheaper. I bought a box of .32 acp last week at wal mart-it was 50 rounds of winchester white box for $15. I have a smith&wesson 432pd chambered in .32magnum. Magnum ammo is hard to come by so I picked up a box of 32 acp for the hell of it. I'll be sticking with the LCP until I can ever locate hollowpoint .32 magnum ammo. One thing you've gotta like about .32 is recoil. It's easy to empty the gun quickly with minimal muzzle movement.
