# Best Aftermarket Glock Magazines: Max Reliability -- ppt/shared-text-box-widget -- Quick, name a brand that the firearms accessory industry supports more than Glock. I’ll wait. You can buy aftermarket parts until your pistol is barely recognizable as a Glock. You can even build an entire "Glock" from non-Glock parts! But what about the magazines that keep your Glock up and running? Those are equally as important as your other upgrades and accessories. So, we're here to talk about the best aftermarket Glock magazines we've found as well as affordable, budget-friendly options. Keep reading! -- ppt/summary-list -- How to Choose the Best Glock Magazines -------------------------------------- Glock itself manufactures high quality and dependable magazines. They can, on occasion, dry up in terms of supply and, like many OEM magazines, tend to be a little pricier than aftermarket. However, they are rock-solid magazines. You can't go wrong with the original. With that said, you can save some money and still get a great magazine by shopping aftermarket. If you want to stock up as many magazines as possible without increasing your budget, aftermarket mags are the way to go. The same goes for more unique products that Glock doesn't offer. How We Test Magazines --------------------- We’ve shot thousands of rounds and spent hundreds of hours with Glocks between our hands-on reviews, shooting events, and guns from our own personal collections. (Yep, some of us carry Glock as our own personal EDC pistol). All hands-on reviews at Pew Pew Tactical adhere to a strict testing protocol which includes 500 rounds through every gun. We also test with both FMJ and JHP ammunition to evaluate reliability with different types of ammunition. We perform standard reloads and tactical reloads to assess each magazine's ability to easily seat into the pistol's magwell. All magazines are evaluated on **reliability, durability, and overall value.** Best Glock Magazines -------------------- ### 1. Magpul - Best Overall **Best Overall: Magpul PMAG Glock Magazines** **Pros** - Super durable and reliable - Meet competition specs - Affordable **Cons** - Lack of witness holes **Specs** - Caliber: 9mm - Capacity: 10, 12, 15, 17, 21, 27, 50 These days, everyone knows the **[Magpul PMAG](https://www.pewpewtactical.com/best-magazines-ar-15/)** is an amazing magazine that revolutionized the AR-15 magazine world. The **Magpul PMAG GL** aims to do the same for Glock owners. At this time, Magpul has plenty of options for 9mm Glocks, including a 140mm, 21-round GL9 magazine that's legal for the USPSA limited class and a 170mm, 27-round magazine for IPSC competition. The magazines are almost entirely made out of reinforced polymer, which makes them tough and stiff. The floor plate is interchangeable with most Glock aftermarket plates, like **[these from Taran Tactical](https://www.pewpewtactical.com/go/rainier/tti-glock-base-pads/ "these from Taran Tactical")**. Magpul magazines drop free without issue, even when empty. They are also pretty dang affordable. Pro shooters and trainers, as well as yours truly, have given them rave reviews. They are just too affordable and high-quality to say no to. There is one downside, though. The majority do not have adequate witness holes. If you're lucky, you'll get a few along the side. Others only have a single hole at the bottom, indicating the magazine is full. Magpul's extended magazines do feature witness holes, which make more sense because these stick outside the magazine well just a bit longer. Overall, however, these are excellent magazines that are effective, affordable, and dead-nuts reliable. In fact, we've reviewed nearly all of them.

Elite Tactical Systems - Best Translucent **Best Translucent: ETS 31-Round Glock Magazine** **Pros** - Easily check ammo count and type - Nice increased-capacity options - Large cartridge selection **Cons** - Questions about clear polymer's durability **Specs** - Caliber: .390 ACP, 9mm, .40 S&W, .45 ACP, 10mm - Capacity: 7, 9, 10, 12, 13, 15, 16, 17, 18, 19, 20, 22, 24, 27, 30, 32, 40 **Elite Tactical Systems (ETS) mags** are some very eye-catching and recognizable magazines for the Glock and AR platforms. They stand out from other magazines because ETS produces them from a translucent polymer, which gives them a unique appearance. In addition to looking cool, the clear nature of these mags provides you with a means to instantly check how much ammo you have left in the gun and even see why type it is. Don't remember which mags have range ammo and which have defensive ammo? Take a peek. ETS magazines are also known for their durability and reliability. They can be dropped over and over, kicked, thrown, and tossed -- they just keep working as smoothly as ever. The same advanced polymer that provides such an unusual appearance is, according to ETS, also resistant to feed lip creep, harsh chemicals, and both high and low-temperature extremes. One of the best things about the ETS is they make magazines for so many different cartridges. You don't need to own a 9mm Glock to enjoy these. You also get options for the Glock G43 single stack 9mm and the Glock 42 single stack .380 ACP in their standard-capacity configurations. Then the extenders come into play. The increased capacity single-stack magazines are my favorite. These mags allow you to carry 7, 9, or 12 rounds of 9mm or .380 ACP, depending on which Glock you own. When we move on to the double-stack magazines, we see a pretty big increase as well. Everyone knows about the **[Glock 18](https://www.pewpewtactical.com/glock-18-review/)** 33-round magazines, and they’re lots of fun at the range. Well, ETS produces extended magazines in capacities of 31, 27, and 22 rounds for 9mm and 30, 24, and 19 rounds for .40 S&W. The 31- and 30-round magazines are designed for fun. The 27- and 22-round 9mm mags and the 24- and 19-round .40 S&W mags are designed to satisfy specific competition regulations. ETS' 22-round 9mm and 19-round .40 S&W magazines are 140 millimeters long and are legal for [**USPSA limited division**](https://www.pewpewtactical.com/choosing-uspsa-division/). The 27- and 24-round magazines are for IPSC and are 170 millimeters long. Speaking of competitions, one final bonus for these magazines is that most Glock base plates will fit on them. This opens you up to base plates from companies like **[Taran Tactical](https://www.pewpewtactical.com/go/rainier/tti-basepads/ "Taran Tactical")**. If you want to see this in action with a full-auto Glock (and you obviously do), check out our **[Glock G18 review](https://www.pewpewtactical.com/glock-18-review/)**! ### 3. Shield Arms - Best Glock 43X/48 Mag -- acf/ppm-deals-widget -- **Pros** - Added capacity - Great for EDC **Cons** - Not as aesthetic as other mags **Specs** - Caliber: 9mm - Capacity: 15 rounds - Compatible with: Glock 43X and 48 Shield Arms is another brand we really like around here. In fact, a **[few of us carry them](https://admin.pewpewtactical.com/pew-pew-writers-carry/)** as part of our EDC. In particular, we really dig the Glock 43X/G48 version that adds a little extra oomph to your compact Glocks. By that, we mean a little added capacity...15 rounds of 9mm, to be precise. The Shield Arms mags are reliable and durable, with a black finish that pairs well with your Glock. We tested them thoroughly in our **[Glock 43X review](https://www.pewpewtactical.com/glock-43x-review/)** and found that they performed great! While they aren't as eye-catching as ETS nor as ubiquitous as Magpul, they offer a solid solution for those looking for a quality aftermarket magazine for a Glock 43X or Glock 48. ### 4. KCI USA - Most Fun **Most Fun: KCI Glock 9mm 50-Round Drum Magazine** **Pros** - More ammo = more fun - Super affordable **Cons** - Not the most durable **Specs** - Caliber: 9mm, .40 S&W, .45 ACP - Capacity: 13, 15, 17, 26, 31, 33, 50 KCI USA is a Korean manufacturer that produces affordable all-polymer magazines. Are they reliable? Most of the time they will cycle and feed just fine. Will they stay together after they’ve been dropped dozens of times? Maybe not. Choose from your standard 15- and 17-round mags for 9mm, as well as a 33-rounder. KCI USA makes a 40-round .40 S&W magazine for Glocks, too. One of their cooler and more interesting options is the [**50 round drum**](https://www.pewpewtactical.com/go/brownells/kci-magazines/). It’s completely impractical and a little expensive, but having 50 rounds of 9mm on tap is a blast. Sometimes ridiculousness is its own reward. What to Avoid When Buying Glock Magazines ----------------------------------------- Not every magazine has to be used for life-and-death scenarios. Sometimes you just want extra magazines for the range. When I go to the range, I want to dedicate my time to shooting, not loading mags, especially if the range charges by the hour. I don’t need magazines designed to go to war to do that, so I’m willing to skimp a little to get more affordable options. If you want some range mags that are both reliable and affordable there are options. Some of these magazines are intended to be used for genuine training, while others are just goofy fun. Not all magazines are great, though, and not all have a price that reflects their quality. These magazines are even unreliable on a static range. So unless you want to get really good at malfunction drills, you should avoid ProMag. ProMag produces magazines for almost every gun out there, even more obscure ones. Unfortunately, ProMag has gained an unflattering reputation. The real shame is with a little quality control they could produce some awesome mags for weird guns. My experience with ProMag has been with their 1911, AK, Glock magazines. They were all frustratingly unreliable. Many retailers will no longer carry them because of customer complaints, so be wary.

Part of that success is due to massive aftermarket support, and the magazine aftermarket has only recently begun to grow. I love that someone besides Glock is making high-quality magazines for the platform, especially since more and more guns are using Glock mags. Go ahead and pick one of these up. It won't be your last. **Am I missing any aftermarket magazine makers you’d suggest? Let us know what you like in the comments. Once you've gotten your mags, it's time to personalize your Glock.
