45 ACP

45 ACP ammo (aka 45 Auto) is the most American pistol cartridge ever to exist! This is the standard round for the Colt M1911, although several other pistols have been designed around John Browning’s great feat of .45 cal magnificence. Choose a bulk 230 grain full metal jacket (FMJ) ammo for target practice, or a jacketed hollow point (JHP) if you need 45 ACP for self-defense. Bullets weighing 165 or 185 grains are both practical if you’re looking for lower-recoil performance. You'll see our in-stock 45 ACP ammo for sale below.

More About 45 ACP Ammo

What is the Difference Between “.45,” “.45 Auto,” and “.45 ACP?”

There really is no difference for these terms, as they are largely used to describe the .45 ACP, which is the official name of the cartridge. When someone says “.45” in reference to ammunition, they are usually referring to the .45 ACP. The same goes for “.45 Auto,” as “ACP” stands for “Automatic Colt Pistol.” However, they may be referring to the .45 GAP, which stand for “Glock Automatic Pistol.” The GAP, however, is much less common than the ACP.

Testing the best 45 acp ammo for self-defense

Is 45 ACP Good For Self-Defense?

Generally speaking, 45 ACP is a slow handgun cartridge but it delivers a lot of energy down range. This makes it a great choice for self-defense shooters. We tested several 45 ACP hollow point options with ballistic gelatin to see how they performed. Find out the best options for 45 ACP self-defense ammo here.

Are the .45 ACP and .45 GAP Interchangeable?

No. Unlike other cartridges (the .38 Special and .357 Magnum, for example), these two cartridges are not interchangeable at all. The .45 ACP was created by Colt’s Manufacturing Company for their line of pistols, while Glock created .45 GAP ammunition for their own products. These cartridges have different dimensions, most noticeably a vastly different overall length.

How Far Can a .45 ACP Effectively Shoot?

The .45 ACP is an effective handgun round for target shooting, but it is generally limited to about 50 yards of effective range, a fairly common maximum distance for handguns. For example, the Gold Medal rounds with 185-grain FMJ bullets (a light bullet for this cartridge), when zeroed to 25 yards, will drop 3.1 inches at 50 yards and almost two feet at 100. This makes using the .45 ACP at distances over 50 yards extremely difficult. You can learn a lot more about the caliber's capabilities in this 45 ACP Ballistics guide.

Is the .45 ACP Ideal for Self-Defense?

Yes. The .45 ACP can deliver effective speed and velocity for personal and home protection. The cartridge has muzzle velocities generally in the range of 800 to 1,100 feet per second, and can go even higher if you are firing +P ammunition. It also delivers muzzle energies approaching 500 foot-pounds, which drives effective penetration and expansion to the target. The only downside for .45 ACP is that it may be too large for some conceal-carry users and could have too much recoil for effective secondary shots. If you are using the .45 ACP for self defense, you will want expanding rounds such as jacketed hollow points.

Is the .45 ACP Better Than the 9mm Luger?

That depends on what you want from your cartridge. If you value sheer strength and stopping power above all, the .45 ACP is your best option. However, the 9mm Luger ammunition is a compact yet powerful cartridge that is ideal for many gun owners.

Which Firearms Commonly Load the .45 ACP?

While there are many weapons that can load the .45 ACP, the most famous is the 1911-style semi-automatic pistols. These firearms can be chambered for many different calibers, but the 1911/.45 ACP relationship is one of the most famous and successful gun/cartridge combinations in the world.
