Nothings more powerful than a man and his 1911 45 Aye See Pee pistol PERIOD! Most powerful cartridge in the world the 45 ACP stands for Forty Five American Cannon Power! Developed by the late great mystical gun wizard John Moses Browning for the Marine Corps to stop the onslaught of drugged up native cannibals because the 38 S&W just bounced off them. One look at the mighty forty five drove off the savages in panic to retreat back and pray for forgiveness. To this day they still pray to the all mighty 1911 pistol! Found this old Shooting Outdoors video that explains the great power of the 45 and how all other cartridges especially any un-American thing that ends in MM are pathetic pee shooters.
