The Glock 43X and 48 are two of the most sought-after Glock pistols in 2024. They have an exceptional reputation for being among the most reliable pistols on the market, and they are also highly customizable and easy to make your own. 

And with all that comes a vast world of factory and aftermarket magazines. 

We will go over all of our favorite magazines and what we recommend you use them for. Most of these can be used universally in multiple roles, but there are reasons why they thrive in certain areas. So, you may see one listed more than once. 

Best of all, these magazines will fit in either pistol. So if you have magazines for one, you have magazines for both!

Are you trying to save weight and carry only what you need? A ten-rounder should do the trick. This is the same magazine that comes from the factory with your Glock 43X or 48, so it’s a great addition to the gun belt for your daily pursuits. 

And since it’s a factory magazine, you don’t have to worry about reliability as much as you would with an aftermarket magazine. It’s a simple plug-and-play.

If 10 rounds aren’t enough for you, another popular option that I’ve seen in many Glock 43X/48 builds is the Shield Arms 15-round magazine. 

Now, using this magazine will take some tinkering since it runs most reliably with the Shield Arms Mag Catch, so if you don’t mind spending a little extra time with your firearm, you’ll be good to go.

One of the best features of this magazine is that it fits in the same footprint as the 10-round magazine. The factory 10-round magazine is a single stack, but Shield Arms simply made this one a double stack, holding five more rounds without being any larger or longer. 

It’s a great choice for concealed carry if you live in a free state.

Range

Glock 48

I’ve had a ton of success with the Glock 48 from an accuracy perspective.

Concealed Carry Drills

You should always practice your concealed carry drills. Having a few 15-round magazines ready for a skills-based range day is a great way to ensure you’re always prepared.

It’s far better than having only ten rounds of 9mm, that’s for sure.  

Less Reloading

By almost tripling your standard capacity, you’ll spend significantly less time reloading at the range. Less time wasted means more time training! These 28-round ProMag extended magazines offer a nice middle ground between the 15-round Shield Arms magazines and the next option.

Not only are drum mags like these great for just sending ammo down range, but it’s also a great way to break in your Glock 43X or Glock 48. You may spend most of your time reloading, but you can stay honed in for a longer period and find your rhythm when the loading is done. 

Thankfully, this magazine does not require any modifications to be made to your Glock 43X or 48 to use. 

You’ll want to pick up a magazine loader while you’re at it.

While 10 rounds would never be my go-to for home defense, you can always pick up a few more and practice some reloads at the range. 

But again, you get that unmatched reliability you expect from a genuine Glock mag, and you don’t have to tinker with the magazine catch for this magazine to work correctly.

More Capacity, Same Footprint

Having more rounds available in a home defense situation is always preferred, especially when it doesn’t increase the size of your firearm. Think of the extra five rounds as an insurance policy that could save your life later. 

While it may not seem like a big difference, five rounds can be the difference between life and death.

If you’re able to own a 20-round magazine in your state, then it would be silly not to have one of these sitting in your bedside gun. You know how the saying goes, “The more the merrier?” Well, 20 rounds of 9mm is a party trick in these small pistols. 

You have to change your magazine catch, but that takes very little time and effort. Glocks are simple that way. 

Difference between the Glock 43X and Glock 48

The only difference between the Glock 43X and 48 is the length of the barrel and slide. Technically, the weight differs because of the extra material used, but outside of those things, everything is the same. Both slimline pistols share the same frame, so the magazines fit into both frames.

Conclusion

Although Glocks come in many different configurations, many parts are interchangeable from model to model, with magazines being a great example. Each of these magazines is meant to get you where you want to be in terms of capacity and performance while being reliable and versatile. 

So, whether you choose the 43x or 48, all of these magazines will do the trick. 

Be good and take care.
