Why So Much Of The 45 ACP Bashing Is Stupid

By Tom Knighton

I follow a lot of firearm and firearm-related websites, as part of my job here at Bearing Arms. I’ll admit that I don’t read every post on every website. There’s just too many of them. However, I do occasionally comes across something that I just have to address.

For example, there’s this one over at The Loadout Room, which is a site I generally enjoy. It argues that .45 ACP is an outdated round.

I really love to stir things up in the shooting community (especially the internet portion of it) so I’m just going to say it, “.45 ACP is outdated.” That’s not to say it isn’t effective, or that it isn’t reliable; just that it’s outdated. The .45 ACP round was developed by John Browning in 1905 and was later adopted by the United States military because it was deemed more effective that the .38 Long Colt that was currently used by many service pistols. For many years it was deemed a superior pistol round to the majority of alternatives available. Because the military is an institution that has historically been slow to make drastic changes, the .45 ACP cartridge was kept in service for a long time before 9mm was adopted as the standard.

The .45 ACP cartridge is large and takes up considerably more space in a magazine than a 9mm round does. The largest of handguns are mostly limited to 13 rounds per magazine (15 in some FN models). When it comes to the 9mm, there are pistols capable of capacities upwards of 17 rounds. The relevance here is that the less ammunition you have in your gun, the more magazines you have to carry and the more often you have to reload; when you’re reloading, you’re not engaged in the fight.
