45 ACP Ammo

The .45 Automatic Colt Pistol (ACP) may be the most iconic American cartridge on the books. It was created for the U.S. Armed Forces by John Moses Browning more than 100 years ago and remains a top choice for military and law enforcement personnel. Civilians also give the .45 high marks when it comes to sport shooting and self-defense. Competition and backyard shooters praise the .45 for mild recoil and accuracy.

Law enforcement agencies continue to use the .45 ACP for its ability to stop dangerous antagonists. Agencies include the FBI’s Hostage Rescue Team (HRT) and the Los Angeles Police Department SWAT. Although the U.S. military replaced the .45 ACP with the 9mm in 1985, Delta Force and Operators of Marine Expeditionary Units under the United States Special Ops Command have the option to use the .45 in their pistols.

When it comes to self-defense the .45 Auto penetrates deep and creates a significant wound capable of damaging the circulatory system, central nervous system, and critical organs.
