Designed by John Moses Browning as a replacement for the "less than stellar" .38 Long Colt cartridge for the U.S. military, the .45 ACP was introduced in 1905. Originally, the .45 ACP had a 200 grain bullet that traveled 900 feet per second. But along with the M1911 pistol, the .45 ACP cartridge was tested by the U.S. Army over the next six years, where both the ammo and the firearm were modified. The bullet weight was increased to 230 grains without a change in the powder load, so muzzle velocity for this new bullet dropped to 830 feet per second – which remained the standard load for its service life.

Sgt. Alvin York in World War I used his .45 ACP to singlehandedly kill six German soldiers while assaulting their machine gun emplacements, supporting the claim of the cartridge as an excellent man stopper. While his story is one of the more famous, other Medal of Honor recipients besides York used the .45 ACP. And since being adopted in 1911 by the military, at least 68 awardees of the Medal of Honor have carried the .45 ACP and the M1911 pistol in the course of their heroic actions.

The .45 ACP is used outside of the Armed Forces in a plethora of applications that include sport shooting, law enforcement and self defense. Target shooters appreciate the .45 ACP for its accuracy, mild recoil and heavy bullet. Major ammunition manufacturers produce .45 ACP in specialty configurations just for personal protection – including Hornady, Federal and Magtech.

Law enforcement agencies that have chosen the .45 ACP for its proven ability to effectively stop dangerous aggressors include the FBI’s Hostage Rescue Team, the Los Angeles Police Department SWAT, and other specialized law enforcement units. The U.S. military officially replaced the .45 ACP with the 9mm in 1985, though it continues to find pockets of dedicated users in the Service. Operators of the Marine Expeditionary Units, Delta Force and others within the purview of the United States Special Operations Command have the option of using pistols chambered in the .45 ACP.

The .45 ACP, after more than a century of use, is a cartridge that has been modified and studied extensively, and is used all over the world. Today, it remains one of the most prized cartridges on the market.

    "I just bought a S&W 1911 E series 41/4" and took it with a box of The Federal 230 HP to the range. At 8 paces, I shot a consistent 4" 7 round group. First time shooting a 45 and with this ammo. I am very certain that the consitancy of this ammo was top notch. I was a big fan of 9mm, but I now have a new love for 45's, after all they are bigger than 40's. I wish I had bought more."
