what he said.Steelheart said:I wouldn't see any reason for a good steel framed 1911 to not be able to handle +P loads. I'd suspect that its a legal thing but to be safe I'd suggest using mostly standard pressure loads with a few +P's for carry if you wish. With the 5" barrel you'll be getting good speed out of the standard pressure loads. I suspect that the target won't know the difference between a +P and a non +P load, where you hit will make a bigger difference. The +P loads will increase the time between your shots due to the greater recoil, the hotter the load, the more recoil it generates.
When I carry my 1911 I use standard pressure loads (mostly 230gr hydra-shok). I did do a conversion to 45 super for when I was in northern Mn but have shot less than 60rds of that. You do know when you touch off a 230gr slug at 1100 fps and it does slow you down between shots. No, I never tried the JHP ammo as I'd rather use 45acp for that type of work.
