I am shooting Winchester ball ammo and plinking ammo from some of the other big manufacturers and getting huge 10" groups at 12-25 yards. I am dead on with a 1911 (sub 2" groups at 25 yards) and less than 3" with a Glock .45 . My friends that shoot with me all notice how terrible the accuracy is. On rare occasion I can get 2 within 2" but after that they fly everywhere. Im starting to wish I had bought a Glock .45 . HELP!
