I frequent bear country and decided to go with Buffalo Bore's 255 gr hard cast in 45 Super. All it took was a extra power recoil spring and guide, I clocked it at right at 1100 fps out of my M&P 45 extended 5 inch barrel. That's bad ass!

I have an M&P 45 and 45c. The fmj 230 grain bullet has a muzzle velocity of 830 fps. Defensive non-plus P JHP 45acp loads in the 230 grain bullet have a muzzle velocity between 870-890 fps. When you mix a magazine with the fmj and jhp ammo, one can feel the difference with when you light off a jhp round. I don't see the need for a +P .45acp round for my use. Usually bullet makers design a bullet to work at a particular velocity, so I feel +P loads for me would offer no advantage.
