The most beloved self-defense round of all time may just be the .45 ACP or .45 Auto. It was created by J. Browning and has seen major action in both world wars, as well as countless other conflicts. There is no other way to classify the round other than one of the single most effective man stoppers on the market. This means that the .45 ACP is one of the first things that potential gun owners are going to shop for when they’re looking for a defensive handgun.

Most of the .45 ACP pistols you see on best-of lists are a batch of the newest 1911 rehashes that really only appeal to folks who like that form factor. I love 1911-style handguns, but there are a lot more pistols out there that fire .45 Auto rounds. This means there should be something on this list for most tastes, purposes, and most importantly, budgets.

What Is So Special About The .45 ACP?

There are entire blog post series about the benefits of .45 Auto. There are easily dozens of reasons that you may choose to go with .45 Auto over any other caliber, but here are the big reasons that the .45 ACP has remained so popular for nearly 120 years.

Proven Performance & Legacy

This is a big one. The .45 ACP has seen official action across two World Wars and several other conflicts, incursions, and operations. It has proven itself across millions of rounds as the supreme self-defense round. The Army as well as the Cavalry decided that they needed something that was far more substantial than the .38 caliber rounds that were letting them down.

It was at this point that they determined that they absolutely needed a .45 caliber round. This led to the production of the .45 Auto, which was similar in ballistics to other .45 rounds of the era, being the standard from its adoption by 1911 until 1985.

This battle-hardened, war-proven performance is what keeps many older shooters loyal, and what draws many new shooters into the caliber. There is a group of enthusiasts that do think that the .45 ACP is over-hyped for its level of performance, but the caliber is a well-established favorite.

Bullets Advance Along With Technology

Since it has remained so popular and prevalent, the bullet market is constantly evolving and changing. Since .45 caliber rounds allow for more machining and refinement at the production level, there is an amazing variety of different types of ammo available for the .45.

The variety and availability of the .45 ACP ammo are some of the strong points of this caliber that will be hard for smaller rounds to consistently imitate. There exists a very large array of bullet weights, load power, tip type, and even materials to choose from.

Since the round enjoys a consistent demand and fanbase, it will continue to remain one of the most common and popular ammunition calibers. This also means that as technology continues to advance and evolve, so will .45 ACP bullets.

Reloading Ease

If you are the type to reload your spent brass, .45 Auto will be one of the better calibers for you to fall in love with. This is true particularly if you are just starting out in the reloading hobby. A great feature of .45 rounds is that they are very forgiving at the reloading bench. Some cartridges are relatively difficult to reload well, but the .45 ACP makes it accessible to even the newest of the newbies.

To a lot of shooters, this may not sound like a big deal. Those shooters probably don’t burn enough brass to make reloading worth it, to be honest. When you take into account the average price of .45 ACP on the shelf, reloading those casings for a tenth of what you paid initially can save you a lot more money than you realize.

Bigger Pistol Frame

Let’s face it, some of us just have bigger mitts than others. This means that our geometry when holding and firing a weapon can be less than ideal. Trying to be nimble with a smaller pistol can be challenging at some points, and downright difficult at others. This makes the often larger frame that makes up many of the popular .45 ACP pistols much more comfortable to hold.

The increased weight of the larger frame can feel more solid and substantial in your hand as well. This can also be a downside, too. If you have smaller hands, it can be incredibly difficult, though not impossible, to safely handle and fire. The weight can exacerbate this issue for those with smaller hands.

This large frame also has the secondary benefit of providing more space for accessories. The longer slide will have plenty of room for a comfortable sight, laser, and even a tactical light. Spacing things out on the larger .45 ACP pistols helps keep your attachments from interfering with your grip.

Are There Any Downsides To Buying A .45 ACP Pistol?

There are tons of upsides, and while these points may not specifically be downsides depending on how you look at them, they certainly may impact your decision or buying process.

Experience

There are many beginner-friendly aspects of .45 ACP pistols, but when it comes down to it, it really isn’t a caliber for a beginner. If you don’t own any other guns and have only interacted minimally with firearms, a .45 caliber won’t be ideal.

The learning curve to become proficient with .45 Auto is also much steeper than with smaller caliber rounds. The bullets are much heavier, and even though they are more powerful, they are often far slower. This can affect ballistics in significant ways, making learning how to shoot on a .45 caliber a very challenging task.

Weight & Recoil

Compared to most pistols, .45 ACP pistols are considered heavy. Many first-timers that pick one up are surprised at how heavy they are for their size. When you fire the gun, you will need to solidly control the weight of that pistol as it recoils. Frequently, the strength of this recoil is relatively strong, and can even cause injury with poor shooting form.

Capacity

As we talked about, .45 ACP rounds are quite a bit larger than many other rounds. Bigger diameter rounds mean fewer rounds in the magazine. Some of this can be mitigated with a double-stack magazine, but the bullets are also heavy, so more of them can really add to the weight. This is one of the compromises that .45 ACP devotees make.

Ammo Cost

This is one that is hard to get around. Sure, you can find some sales here and there, bulk order with some friends or neighbors, but anyway you slice it, .45 ACP ammo is not cheap. This is another compromise that we make for the love of the .45. It’s understandable, the bullets are bigger, heavier, and more powerful than smaller calibers, so there are more materials and machining needed.
