Like many things in life, the .45 ACP cartridge has seen dips and spikes in its popularity.

However, a few departments went with a new gun chambered for the .45 ACP.

During the 1990s, the fortunes of the .45 ACP began to change for the better.

In 1986, agents of the FBI were caught up in the most studied gunfight of all time.

[See Dan Abrahams article on10mm vs. No doubt, this boosted the popularity of pistols chambered for .45 ACP.

The classic pocket pistols were indeed handy, but reliability was suspect, especially when fed hollowpoint ammunition.

Shooting a pistol chambered for the .45 ACP cartridge isn’t as unpleasant as some people might have you believe.

So, what happened?

In short, more powerful cartridges generate slightly greater recoil and muzzle flip than the mild-mannered 9mm.

Four different scenarios inside of 7 yards were devised, and all firing was done at game speed.

Can I Really Manage a .45?

Pistols chambered for the .45 ACP can be managed by most anyone who commits to a regular practice regimen.

Despite rumblings to contrary, this specifically includes smaller-stature people.

Federal HST 45 ACP cartridges expanded bullets

One of the things that sets the .45 ACP apart from others is the massive bullet expansion that is possible. Shown here is a pair of Federal HST .45 bullets that expanded into gel after passing through heavy clothing.

But is it manageable?

Ive run a steel-frame 1911 in classes, firing several hundred rounds a day with no ill effect.

However, when firing lighter and/or smaller guns, the game can change 180 degrees.

Surprisingly, polymer-frame pistols chambered for .45 ACP are actually quite pleasant to shoot despite their light weight.

The polymer somehow dissipates felt recoil, and thats okay with me.

Put a realistic size, humanoid target up and move yourself five yards away.

The micro-sized Hellcat offers users a powerful and extremely compact EDC pistol chambered in the popular 9mm cartridge.

Load and charge with a five-round magazine and place it in the holster.

Can you get it done in five seconds or less with all hits in the high-value area?

If so, you might be on to something.

Myth vs.

Heavy clothing has a nasty habit of fouling the cavity and retarding or totally preventing expansion.

But if expansion is compromised in any way, a larger diameter bullet will have an edge.

This may be a valid consideration for those who live in cooler climates.

Assuming equal penetration and optimum expansion, the larger projectile will cause greater damage to a target.

However, as much as I like the .45 ACP I dont attach any magical qualities to it.

However, I am not exempt from magazine capacity restrictions.

If Im restricted to carry a 10-round magazine, mySpringfield Armory XD Compact in .45 ACPwill get the call.
