I'm afraid I'm going to have to carry FMJ, since my gun is notorious for having problems with JHP.
Wish I'd found that out before buying.
Check out Cor-Bon Pow'R Ball. It's a JHP with a polymer cap to give it the profile of a FMJ round. I've read that the terminal performance can be kind of dicey but it's better than JHP that jams or FMJ that doesn't expand.
