I bought a new Glock 21 today at the gun show. I've wanted one for a long time, mainly to shoot pins and for fun. I stopped by the Georgia Arms booth and picked up some 230 grain Gold Dots. Got home and looked at the package and see that the ammo is .45 +P. Guess I should learn to look more closely at the label, though I never knew there was such thing as +P in .45. Anyway, my question, is .45 +P a punishing round (for the shooter, that is)?
