Frequently Asked Questions

Is .45 ACP the same as .45 Auto?

Yes, .45 ACP and .45 Auto refer to the same cartridge. The “ACP” stands for Automatic Colt Pistol, in reference to the Colt 1911, which was designed around the .45 ACP as the U.S. military looked to replace its service revolvers with semi-automatic pistols.

What is the best .45 ACP ammo for self-defense​?

The .45 ACP can be a great defensive round with the right ammo selection. Which .45 ammo is best for self-defense largely depends on personal preference, but a few options stand out among the rest.

The Federal Premium Personal Defense Hydra-Shok .45 ACP Ammo 230-grain JHP is a popular choice that offers impressive penetration and expansion. If you want a slightly lighter round, the Hornady Critical Defense .45 ACP Ammo 185-grain FTX packs a punch without breaking the bank.

What is the best .45 ACP FMJ ammo?

The best .45 ACP FMJ ammo depends on what you’re after. If you want the most bang for your buck, Independence Ammunition’s .45 Auto Ammo 230-grain FMJ ammo comes in low-cost bulk packs without sacrificing dependability. Others swear by PMC Bronze .45 ACP Ammo 230-grain FMJ ammo for its reliability.

Will a .45 ACP kill a bear?

With the right ammo and shot placement, .45 ACP is capable of taking down a bear. However, you’d be safer with a higher-energy cartridge. If you do plan on taking your .45 with you for bear defense, be sure to stock up on .45 ACP FMJ ammo instead of hollow points, as you’ll need the extra penetration.

Is .45 ACP subsonic?

Yes, most .45 ACP ammunition is subsonic, even if it doesn’t say so on the box. With many other cartridges, it takes special, low-pressure loading to stay below the sound barrier, but standard-pressure .45 ACP rounds leave the barrel well below that mark.
