I carry a Glock30 with FMJ 165gr Federal. I've read that JHP would probably be an overkill for .45 and its not needed for stopping power. Yet, I also see JHP are more effective and I'm considering switching over to JHP. What do you think about carrying a Glock .45 with JHP as to FMJ? Recommonded or not? And whats with .45 GAP (Glock Automatic Pistol) ammo? Should I be buying GAP ammo? Whats the difference in recoil (if any)? Thanx
