All combat handguns are under powered, don't create hydrostatic shock, and are better off with heavy for weight bullets that push a big expanded bullet face deeper rather then waste its energy creating minor and unhelpful shock like a lighter for caliber, higher velocity bullet will. The whole high velocity handgun thing was a big psuedo science thing of the late 1970's and the entire idea of the 185 grain hollow point in 45 ACP came from wanting reliable expansion with the poorer bullets of back then, and also bad science about what made handgun rounds effective. So, in 45 ACP, terminal ballistics wise, 230 grain is where theoretical peak performance lies. Check out gel tests, and this conclusion is observable.
