The Glock 22 was introduced in 1990 as part of the wave of .40 S&W pistols hitting the market when everyone was going crazy over the Miami-Dade FBI shooting. In search of a larger round with more stopping power, law enforcement agencies desperately wanted something better.
Being the same size as the Glock 17, the Glock 22 was a hit among agencies and still serves in departments all over, including Baltimore, Los Angeles, and, you guessed it, Miami. It also serves as a duty weapon for multiple agencies in Australia and New Zealand.

The beautiful part about Glocks is that the magazines for the Glock 22 are all compatible with each other from Gen 3 and forward. So, if you have a Glock 22 Gen 4, your Gen 3 and Gen 5 magazines will fit.
Now that we have that established, let’s dive in.
Everyday Carry & Home Defense
Tried and Tested
The factory magazine for your Glock 22 will always be the best option for defending yourself and your family. Since your Glock 22 was tested and left the factory with these mags, you can trust that they will always be reliable.
And that your pistol will always be reliable with them.
Constructed from a durable polymer and featuring full-length steel inserts, these magazines are ready to handle any task. With a 15-round capacity and rear-facing facing witness holes to help you keep track of remaining rounds, there isn’t much else you can ask for.
For Magazine Capacity Restrictions
Suppose you’re unfortunate enough to live in a state where politicians have dictated that anything over ten rounds is a war crime. In that case, you’re going to need as many backup magazines as possible to have an edge over the bad guy.
These are factory 10-round magazines, so you can rest easy knowing that your Glock 22 will function perfectly fine while using them. They utilize the same durable construction as the 15-rounders and also have those convenient rear-facing witness holes.
Factory Extended Option
Who said the bad guy is the only one who can use an extended magazine with his Glock?
Like the other factory magazines in this list, this 22-round magazine comes directly from Glock, so you can be more sure about your firearm’s reliability.
Why not bump up your capacity, just in case? From the range to home defense, these can definitely come in handy.

Extended Magazine
If there’s one thing about Glock pistols, it’s that they will have a ton of extended magazines available. The first extended mag we’ll discuss is a 31-round polymer option from SGM with a matte black finish.
From a material perspective, they are similar to the factory Glock extended magazines that I mentioned above and will definitely work well with your Glock. Appreciated features include rear-facing witness holes and a removable baseplate. Best of all? They don’t break the bank.
Clear Extended Magazine:
If you’re a fan of clear magazines, then ETS is one of the best companies in the business producing them. Its magazines are reliable and durable and add some style to your firearm.
Clear magazines are extremely helpful for tracking how many rounds you have left. It’s also a nifty party trick to see your bullets getting higher and higher, or at least that excites me.
If you’re looking for an extended clear mag, I can recommend nothing more than these from ETS.
Drum Magazine:
We’re going for maximum ammo capacity for this one. A magazine that weighs more than your Glock 22 is equivalent to holding a five-pound weight in front of you. Sounds fun, right? I know it was for me.
Made from polymer with steel feed lips, these mags take a beating for quite some time before showing their age. And odds are, they’ll most likely last your whole shooting lifetime especially if you’re a more conservative shooter.
With a hand-crank loading mechanism, you can get your 50 rounds loaded quickly and efficiently. And they are made right here in the USA!
Accessories
What is the most natural yearning of every shooter? If you guessed more ammo in the magazine, then you guessed correctly.
This grip extension adds two rounds to your magazine and gives you extra real estate for your hands to get a full grip. Two rounds may not sound like much, but they could be the difference between life and death, literally.
Having a magazine loader is a great way to make sure you’re spending more time shooting and less time reloading. It saves your thumbs, it saves your time, and it makes you a better shooter (cause you spend more time shooting, you know)
This loader is universal, so you don’t have to worry about buying multiple loaders if you own different caliber pistols. Just one and done. And they last a long time.
Conclusion
The Glock 22 is a great pistol. Although the effectiveness of the .40 S&W has been in question over the years, it still serves as a fine sidearm for many law enforcement agencies all across the globe, so you can rest assured that they have been tested to the extreme.

And so have these magazines. No matter which you pick, you’re sure to get years of use before ever having to come and see us for a replacement.
So go ahead and get your spares, get your drum mags, and get to shooting.
Be good and take care.
