.45 Auto (ACP) cartridges drive 185- to 230-grain bullets at 830–1,000 fps for 320–400 ft-lbs of energy, delivering the time-tested balance of manageable recoil and real-world stopping power in 1911 pistols, polymer-framed carry guns and steel-frame duty pistols. Full metal jacket (FMJ) loads ensure smooth feeding and economical range sessions, while jacketed hollow point (JHP) rounds provide reliable expansion and deep penetration for self-defense and law-enforcement applications. From subsonic 230-grain loads optimized for suppressor use to +P offerings that boost velocity for tougher performance, .45 ACP ammo adapts to every shooter’s needs. Top manufacturers like Federal, Hornady and Winchester load .45 Auto ammunition on quality brass with consistent primer ignition for flawless cycling.
