The .45 ACP (Automatic Colt Pistol) cartridge was developed by legendary American firearm designer John Moses Browning 1904. Its most notable application is the iconic Colt M1911 pistol which served as the standard-issue handgun of the U.S. military between 1911 and 1985.

.45 ACP ammo may have been eclipsed in popularity by the 9x19 Luger cartridge, but it still has a dedicated following among sporting shooters, hunters and fans of the Great Outdoors.

Despite having considerably more recoil than 9mm ammo, the heavy .45 ACP rounds are appreciated for its high stopping power, which is essential for hunting or self-defense.

FAQs about .45 ACP Ammo

1.        Is .45 ACP ammo and .45 Colt ammo the same?

Even though they share the same caliber of around 0.45 or roughly 11.15mm, the .45 ACP and the .45 Colt are not identical. The .45 Colt was developed for the Colt Single Action Army revolver in 1872 and is much longer than .45 ACP. As such, you cannot fire .45 Colt rounds from a .45 weapon.

2.        What are .45 ACP +P cartridges?

Some .45 ACP ammo has a “+P” designation, which stands for overpressure ammunition. This ammo is loaded with higher pressure, which results in the higher velocity of the projectile, more muzzle energy and more stopping power as a result. This ammo is fully compatible with all .45 ACP weapons, but tends to be more expensive.

Most states throughout the U.S. allow individuals 21 or older to buy ammunition online. NY, DC, HI, MA, CA and IL have shipping restrictions on ammunition. See our customer service page for details.
