Federal American Eagle Indoor Range Training 45 ACP Brass TMJ 230 Grain 50 Rounds
.45 ACP is the cartridge that made the 1911 famous. Big, heavy bullets at moderate velocity give it a reputation for stopping power and a soft, rolling recoil that is a pleasure at the range. At Gunners Outlet we carry .45 ACP ammunition from 155 to 230 grains, including classic 230 grain FMJ, +P loads and defensive hollow points like Speer Gold Dot and Federal HST. Brands include Federal, Remington, Sig Sauer and PMC, all shipped fast from our New Hampshire warehouse.
Choosing .45 ACP Ammunition
John Browning developed the .45 ACP for the U.S. Army, which adopted it with the M1911 pistol in 1911. It served as the standard American sidearm round for most of the century and remains a favorite for competition, home defense and carry.
The standard weight is 230 grain, and a 230 grain FMJ is the go-to range load. Lighter 165 to 200 grain loads run a little faster with snappier recoil, and some shooters prefer them for competition. +P loads add velocity for defense but should only be used in pistols rated for them.
For concealed carry and home defense, a quality JHP is the right choice. Because the .45 starts with a wide bullet, a good hollow point expands to an impressive diameter while staying controllable. For training, buying .45 ACP FMJ in bulk is the smart way to keep cost per round down.
.45 ACP for Competition and Suppressors
Standard 230 grain .45 ACP is naturally subsonic, which makes it one of the best pistol cartridges for suppressed shooting without special ammo. It is also popular in competition, where its heavy bullet makes major power factor easy and its slow recoil impulse helps fast, accurate shooting.
Classic pistols like the 1911, Glock 21 and Sig Sauer P220 have long histories with this cartridge. Brass-cased .45 ACP is easy to reload, which helps high-volume shooters, and buying FMJ in cases of 500 or 1,000 rounds brings the price per round down.

Frequently Asked Questions
9mm vs 45 acp: which is better?
Neither is universally better: 9mm offers more capacity and lower cost, while .45 ACP fires a heavier, wider bullet. With modern hollow points the performance gap is small, so many shooters choose 9mm for capacity. Others prefer the .45 for its soft recoil impulse and proven record.
45 auto vs 45 acp: which is better?
They are the same cartridge, so neither is better. .45 Auto is simply another name for .45 ACP (Automatic Colt Pistol). Ammo labeled either way fits any pistol chambered for .45 ACP.
45 gap vs 45 acp: which is better?
.45 ACP is far more common, while .45 GAP is a shorter version that fits smaller frames. Ballistics are similar with standard loads, but .45 ACP ammo is much easier to find and usually cheaper. The two cartridges are not interchangeable.
What is the best 45 acp for concealed carry?
The best .45 ACP for concealed carry is a proven bonded or premium hollow point, such as Speer Gold Dot or Federal HST, in a weight your pistol feeds reliably. Test at least a few magazines through your carry gun before you trust it.
