Originally drafted by John Moses Browning in 1904 to address the U.S. military’s need for greater stopping power—evident during the Moro Rebellion—the .45 ACP entered service in 1911 in the iconic Colt 1911 pistol and served as the standard sidearm for over seven decades. Its enduring reputation for reliable knock‑down power, subsonic velocity, and controllable recoil make it a favorite among shooters today—ideal for concealed carry, competitive shooting, home defense, and even use in submachine guns and suppressed firearms.
All our inventory is live—no backorders or drop shipping. With fast shipping from our warehouse and competitive bulk-case pricing, SGAmmo makes it easy to stock up on .45 ACP ammo for defense or the range. Shop now and lock in the best deals on this legendary pistol caliber!
