Choosing Glock Mags: Common Questions and Answers

Need some new Glock mags for your pistol? Planning on buying an aftermarket brand? Make sure you know the answers to these questions first!

Are All Glock Mags Interchangeable?

Some Glock mags are interchangeable and others are not. For instance, a G19 may accept a standard G17 mag but a G17 will not accept a G19 mag. A G43X mag may fit a G48, but a Glock 43 and G43X will not accept the same mag, regardless of being in the same caliber, because the magwells are not the same.

Remember, even if two Glock pistols are chambered alike, the width of the magwell, the length of the magazine, the generation, and whether or not it is a single or double-stack model will all affect compatibility – so don’t take chances, if you have questions consult Glock or the seller of the magazine.

Does Generation Matter?

Yes, generation can influence the compatibility of Glock mags. It’s best to buy a mag compatible with the generation of your Glock to avoid equipment/feeding malfunctions.

Can You Buy Glock Mags Online?

Yes, check out a venue like Bucking Horse Outpost. They sell a wide range of firearm mags as well as ammo and other shooting accessories.

Do Glocks Have Magazines or Clips?

Despite the fact that some shooters wantonly refer to magazines as clips, Glocks accept magazines, not clips. A magazine both stores ammo and feeds it into the action, whereas a clip is a device used for storing ammo and sometimes for charging mags.

Are Extended Mags Worth It?

That depends, but they can be. For instance, if you have large hands and own a G42, a larger mag (or a mag extension) can add not only capacity to your handgun but also afford you a better, surer grip on the gun.

On the flipside, if you get one of those larger drum mags, it can make handling and holstering the firearm substantially more difficult. Extended mags on a Glock 17 or G19 might not badly affect handling but can affect carry and holstering. Take it on a case-by-case basis.

Are High Capacity Mags Illegal?

That depends on where you live. Some states and cities have magazine capacity restrictions so be aware of these before buying and consult a lawyer in your state if you are unsure.

Are Polymer Mags Better?

Maybe not better, but polymer mags have a lot of advantages over steel and aluminum mags. While they’re not as strong, they are pretty tough, don’t get dented, and most importantly, aren’t prone to corrosion.

How Do I Break In a Glock Mag?

The easiest way is by using it. You can also use a speed loader to load and unload the mag 10 to 20 times which will help speed up the process.

How Often Do I Need to Clean a Glock Mag?

That depends on how much you use it, but a good rule of thumb is after 100 rounds or so. If you go through more than this during a session at the range, it’s a good idea to break it down and clean it after you get home.
