If you’re reading this, then we probably don’t have to tell you that the Glock™ is one of the world’s top firearms and an essential weapon for military and law enforcement agencies around the globe. The Glock™ has plenty of factors working in its favor, boasting unmatched reliability, a lightweight design, and an above-average magazine capacity.

But like any firearm, a Glock™ can only perform to its highest potential when it is properly loaded with the right ammunition. So, what ammo does a Glock™ use? You need to know exactly which Glock™ handgun you have to answer that question.

We’ve put together a handy guide to choosing the right ammo for Glock™ handguns, covering the most popular models made by the manufacturer.

Essential Ammunition Terms

Before you start browsing Glock™ ammo for sale, you should have a solid understanding of how bullets are measured. This means learning about the most important parts of ammunition and the purpose each serves:

  • Cartridge: The cartridge includes the bullet, casing, primer, and powder, which are all necessary for the propulsion of the bullet.
    • The bullet is a metal projectile, which will be shot out of the mouth of a firing cartridge.
    • The casing is a tube, typically made from brass, which contains and holds together the entire cartridge.
    • The primer is a special cap located in the head of the cartridge, which ignites the powder when struck by the firing pin.
    • The powder, or gunpowder, will explode when the gun is firing, generating the energy to propel the bullet forward.

As you look for bullets for Glock™ handguns, you can expect to see these key terms referenced regularly. Now that you’re familiar with what each one means, it’s much easier to be a confident and informed shopper.

Types of Ammunition

There are many different ammo types out there, with a handful that tend to be the most common:

  • .22 LR: Typically used for training and sports shooting, this rimfire cartridge is rarely paired with Glock™s.
  • 9mm: The most common caliber and widely-used ammo out there, the 9mm is often used as Glock™ ammo.
  • .380 ACP: Referred to as a “three-eighty,” this is usually seen in smaller handguns.
  • .40: Larger and slower than a 9mm, this ammo will generate more recoil.
  • .45 Auto: Even larger than a .40 caliber bullet, this ammo type increases the recoil factor even more.

Of these common types of ammo, many are frequently recommended for Glock™ handguns. A few types are not on this list because they are far rarer, though they may occasionally be suggested for use with a specific Glock™.

What Ammo Does a Glock™ Use?

The right ammo for a Glock™ will depend on the specific handgun’s identity. In other words, you’re going to need to learn a little bit about which Glock™ you have to know what ammo to use with it.

Some of the most popular handguns by Glock™ – and the ammo they use – include:

  • Glock™ 17: The well-known Glock™ 17 is one of Glock™’s smaller handguns. The correct ammo for a Glock™ 17 is 9mm, sometimes marked 9×19.
  • Glock™ 19: Considered the most popular Glock™ handgun, the Glock™ 19 uses 9mm ammo.
  • Glock™ 20: With a little extra power, the Glock™ 20 requires 10mm auto ammunition and isn’t seen quite as often.
  • Glock™ 21: This high-powered handgun takes .45 Auto ammo.
  • Glock™ 22: A standard-issue Glock™ 22 will be paired with .40 caliber ammunition.
  • Glock™ 23: Slightly more compact than the Glock™ 22, the 23 similarly uses .40 caliber ammo.
  • Glock™ 26: This impressively compact handgun (one of the most compact on the market today) requires 9mm ammo.

Do you have a Glock™ that’s not on this list? Don’t make the mistake of simply guessing which ammo it requires. No matter what model you’re working with, the correct ammunition is a must.

The good news is that it’s pretty difficult to get the wrong ammo to fit in and fire from a magazine or handgun it’s not compatible with. Generally, you’ll realize you’ve made an error when the ammo doesn’t even properly fit. That being said, it can be possible – through pretty unlikely – that you do fire the wrong bullets from a handgun. In that situation, the best-case scenario is faulty performance, while the worst-case scenario is a damaged firearm or even an injury to yourself.

So, above all, make sure you choose the right ammo every single time.
