What’s not to love about higher-capacity magazines—more is better, right? Especially when you’re out there on the range having a blasting good time. You can shoot longer between reloads, and heck, they look cool too. If you’re looking for a Glock 30 round magazine or better, we’ve got several high capacity Glock magazines at GunMag Warehouse that are looking for their forever home. Daniel made some videos to show them to you from 33-round OEM mags to 40-round ETS after-market extendos.
Check out the videos below to see which models will work for you.
These first two videos are about the Original Equipment Manufacturer (OEM) Glock Gen 4/5 33-round factory 9mm magazines. OEM means that they were made by another company for Glock to meet Glock’s quality and standards. Of all the 33-rounders out there, Daniel says this is the most reliable for your handguns or pistol caliber carbines. Combining impact-resistant polymer with tough steel inserts and steel springs, it’s an all-around great magazine with the sturdy construction that you expect from Glock.
This mag fits Glock 9mm pistols from Gen 3 to Gen 5. You can even use it to feed a Glock 26, but it’s going to stick out just a little bit (you think?) But hey, this probably isn’t something you’re going to conceal.
It has witness ports on the back to tell you how many rounds you still have in the magazine, but be aware that even though it says 31 at the bottom, the +2 extension brings the capacity to 33 rounds.
This Glock extended magazine fits all double-stack 9mm models including 17, 18, 19, 26, 34, 19x, and 45 pistols.
These magazines are available in three color options. Take a look at the black one:
If you prefer Olive Drab Green (OD) or Flat Dark Earth (FDE) GunMag’s got you covered. Daniel prefers OD, saying, “OD is life to me!” Also, OD and FDE come with a high visibility orange follower to help you gauge how many rounds are left in the mag with a quick glance.
Again, these are 31-round capacity Glock OEM factory magazines with a +2 extension, which takes them to 33 rounds. Check them out in the video below:
They run great and feed the gun the way it’s supposed to be fed. All around great construction, great quality you expect from Glock.
Glock 9mm magazines are duty-tested and combat-ready—trusted by law enforcement and military professionals from all around the globe. Glock magazines are designed to drop free and provide ultra-reliable performance in any situation …
Glock magazines come with a very strong spring rate from the factory to ensure reliability in the toughest of conditions. Sometimes, magazines are found to be a little bit difficult to load at first. We recommend using a magazine loader to ease the loading process. However, after a few times loading and unloading, the springs break in nicely and it becomes much easier to load.
After Market Options
GunMag Warehouse also offers several aftermarket high capacity Glock magazines. Generally speaking, aftermarket magazines have a polymer construction, which makes them more affordable than OEM magazines. But that doesn’t mean they aren’t worthy of consideration. Today’s polymers are pretty darn tough, and on the off chance that something does happen to your after-market magazine, these mags come with some incredible warranties.

And, beyond the extra capacity that these mags offer, they’re made in the USA, with an amazing warranty. If this magazine gets destroyed somehow, the folks at ETS don’t care how it happened. Just send the pieces back to them, and they’ll send you a new magazine. You just can’t beat it out there in the magazine game.

Now, they’re going to ask questions. When Daniel asked them about the warranty, they said, “Yeah these magazines don’t break often so we’re going to figure out what happened. But we’re going to take care of it no matter what.”
This Glock 18 magazine from Elite Tactical Systems, you may notice, is not your normal Glock 18 magazine. It’s a 31-round magazine for feeding hungry double-stack 9mm Glocks, and it’s blue.
Although this blue magazine may not be for everybody, Daniel personally digs this color, “But it may not be the color for some of the baby bluemers out there.” See what he did there?
Plenty of other people will probably dig this color in their gun. It’ll look great for Instagram and all that good stuff.
Daniel says he’s “…tried a lot of magazines out there, some of them were good some of them were not so great. Some of them just straight up blew, but the ETS does not. They are blue but it does not blow. I’ve been shooting ETS magazines for quite a while. The Glock 18 kinda blue me away.”
They’re great magazines with the same great ETS warranty mentioned above. You can feed your double-stack 9mm Glock until you are blue in the face.
All puns aside, if you break this magazine for whatever reason ETS is going to take care of it for you and you’re going to have a great time shooting this thing.

The KCI Glock 17, 19, 26, 34 9mm 33-round polymer magazine is designed for use with the Glock Gen 3 or later, and won’t work with your single stacks, obviously.
