I carry Federal HST +P rounds (in .45 though). A lot of people carry Gold Dot +Ps. A lot of people also carry Hydra-Shoks. I would recommend looking at which ammo law enforcement uses. After all, if we are forced to use our firearm, we need a quality round to do the job just like they do - and they have paid for studies to be done on theirs. I do not recommend Federal's regular "Personal Defense" ammo - the .45 is weak sauce.
