When choosing the best pistol caliber, there are many options to consider. Some people prefer the tried and true 9mm, while others swear by the power of the .45 ACP. However, one caliber stands out above the rest: the 10mm. This article will explore seven reasons the 10mm is the best pistol caliber.

1. Power

One of the biggest advantages of the 10mm is its power. It was originally designed as a cartridge for the FBI, who wanted a round that could penetrate body armor. The 10mm delivers more energy than most other pistol calibers, with a muzzle energy of up to 800 foot pounds. This makes it an excellent choice for self-defense, especially in situations where you may need to shoot through barriers.

2. Versatility

Another reason why the 10mm is the best pistol caliber is its versatility. It can be loaded with various bullet weights and types, making it suitable for everything from target shooting to hunting to self-defense. For example, you can load it with a heavy, slow-moving bullet for maximum penetration or a lighter, faster bullet for greater accuracy and less recoil.

3. Accuracy

Speaking of accuracy, the 10mm is also one of the most accurate pistol calibers available. Its long, straight-walled case provides excellent support for the bullet, which helps to keep it on target. The 10mm has a relatively flat trajectory, making shooting accurately over long distances easier.

4. Recoil

Despite its power, the 10mm has relatively mild recoil compared to other high-powered pistols calibers like the .357 Magnum or .44 Magnum. This is because the 10mm operates at a relatively low pressure, which helps to reduce felt recoil. Additionally, the 10mm is often chambered in larger, heavier guns designed to absorb recoil, reducing its effects on the shooter.

5. Availability

One of the drawbacks of some less common pistol calibers is that they can be difficult to find. This is not the case with the 10mm, widely available at most gun stores and online retailers. Additionally, many manufacturers produce 10mm ammunition, so you have many options when selecting the right load for your needs.

6. Reliability

The 10mm is also an extremely reliable cartridge. It was designed as a duty round for law enforcement and military use, so it has been extensively tested in various conditions. Additionally, the 10mm has a reputation for feeding and cycling reliably in most firearms, which is important for anyone who relies on their gun for self-defense.

7. Fun factor

Finally, it’s important to remember that shooting should be fun! And there’s no denying that shooting a high-powered 10mm can be fun. The recoil is manageable enough that most people can shoot it comfortably but powerful enough to give you a real sense of satisfaction when you hit your target.


Whether you’re looking for a powerful and versatile round for hunting, self-defense, or just some fun at the range, the 10mm offers many advantages over other popular calibers. Its impressive stopping power, accuracy, and manageable recoil make it ideal for many shooters. So if you’re considering investing in a new handgun or trying out a new caliber, give the 10mm a shot – you won’t be disappointed.
