There is a cult among gun owners. They’re secretive in person but loud online. They often hide in the corners of the internet, waiting for their beloved object of obsession to be mentioned. The cult of the 10mm is strong and always has been. While small, they are easy to find. Go to any forum and ask, is the 10mm worth it? They shall reveal themselves to you! 

The Mighty 10mm

Okay, paranoia hat off, but seriously, the 10mm keeps a cult following four decades after its invention and last duty use. Jeff Cooper had an idea, and Norma had an engineering department. What emerged was one caliber to rule them all. It would be more powerful than 9mm but provide more capacity than 45 ACP. FBI adoption of the round after the ’86 Miami FBI Shootout guaranteed a degree of immortality to the cartridge. 

While it’s fallen out of vogue with government agencies, the round is still popular. It’s quite versatile and can be loaded light for enjoyable plinking or heavy enough to take bear if need be. Somewhere in between sit some excellent defensive loadings. The 10mm is a great cartridge, and if it interests you, you might be wondering what rifles and handguns are available to you. 

You’ve come to the right place! 

The Best 10mm Handguns and Rifles 

FN 510 Tactical 

The FN 510 Tactical is one of the latest 10mm polymer frame, duty-type pistols on the market. If we are looking at duty-sized handguns, the FN 510 takes the cake from Glock, S&W, and the 1911 world. The FN 510 Tactical is a beefed-up FN 509 series that’s adorned with all the modern features you could throw a stick at. 

Those features are why the FN 510 Tactical beats the competitors. Of course, we get removable backstraps and a Picatinny rail, but it’s more than that. It comes ready with a threaded barrel.

The FN 510 gives you all the modern attachments

That allows you to add a muzzle brake to trim some recoil from the mighty 10mm or a suppressor to take advantage of those subsonic loads that are available. 

The rear of the slide features an optics-ready configuration that uses a replaceable plate system to utilize a wide variety of optics. When you consider the flat shooting nature of the 10mm, a red dot makes a lot of sense to wring out all the range possible. FN even includes suppressor height sights for that potential suppressor and red dot addition. To top it all off, the gun comes with a 15-round flush-fit magazine and a 22-round extended magazine. 

Glock 40 

Glock has been fans of the 10mm for quite some time. They’ve consistently produced the Glock 20 and Glock 29, even when the popularity of the centimeter dipped. While the G29 and G20 are fine firearms, my personal favorite is the Glock 40. Glock’s 40 isn’t a 40 S&W, but a 10mm, although the 10mm evolved into the .40 S&W. At this point, I’m pretty sure Glock’s naming convention is on purpose at this point just to mess with us. 

The Glock 40 is built on the Glock 20 frame but utilizes a 6-inch barrel. A longer barrel offers a few advantages.
