Before I got rid of it, my little LCP ran Hornady TAP and Corbon just fine. I stopped using Hydra-shocks a long time ago when they got a little outdated. Corbon's, HST's, Ranger T's, Hornaday Critical Defense/Z-max all good stuff. I know the Critical defense was actually designed with the LCP in mind being its barrel is so short it has a hard time achieving velocities to open hollow points properly.
