.45 ACP

The .45 ACP (or .45 Auto) cartridge is a truly American icon. It was designed by J. M. Browning in 1904 as a standard chambering for Colt’s M1911 semi-automatic pistol. Both the M1911 pistol and its new version M1911A1 appeared in 1924 were standard-issue sidearms in the U.S. military for more than 70 years until the M1911A1 was replaced with the 9mm Beretta M9 in 1985.

Though the 9mm offers lots of advantages and few downsides on which you can easily compromise, the .45 ACP cartridge is still very popular and has its advocates among both law enforcement agents and civilians. Such lasting popularity contributed to the development of various .45 handgun designs.

If you are a novice shooter with no experience in handling a .45 ACP pistol, then maybe consider some other options chambered for 9mm or even less powerful cartridges. Why? The .45 ACP gives more felt recoil which can lead to the development of flinch if you are new to shooting. The size and weight of a handgun can make a difference, though. The bigger the gun, the less recoil it will give.

One more downside of .45 guns is reduced capacity due to the diameter of the round. For example, a common 1911 pistol in .45 ACP holds 7+1 rounds, while Glock 19 in 9mm holds 15+1.

But, as far as home defense is concerned, .45 ACP is preferable. As the .45 ACP bullet is slower-moving because of the reduced energy, it is less likely to go through walls or furniture and hit your beloved ones.

A .45 semi-auto handgun is also easy to reload since the .45 ACP cartridge is straight-walled.

Modern 9mm cartridges possess as much stopping power as the .45 ACP, so the latter should not be treated as some kind of ultimate knockdown round. Still, some people just love .45 ACP for what it is and that’s enough. You just need to know the pros and cons of it to have any situation under control.

Most popular .45 ACP chambered handguns are 1911-style, but due to the popularity of the cartridge the market doesn’t suffer from the shortage of various .45 ACP solutions like Glock G21 Gen4, FN FNX-45 Tactical, Sig Sauer P220 Legion, H&K HK45 Compact, and many others.
