Keeping Traditions Alive Since 1953

The Glock 43X and 48 are outstanding pistols, but the standard 10-round factory magazine leaves a lot of capacity on the table. ETS Group's GLK-43X-19 extended magazine changes that in a big way, pushing capacity up to 19 rounds of 9mm without requiring you to swap to a completely different platform. That's a serious upgrade for range days, competition shooting, or anyone who just wants more ammo ready to go.
The most immediately obvious feature is the fully translucent body. Unlike traditional opaque polymer mags where you're stuck counting witness holes, the clear construction gives you an unobstructed view of exactly how many rounds are loaded and what type of ammo is inside. It's a genuinely useful feature that goes beyond aesthetics.
The polymer itself is purpose-built for durability. It's impact resistant so it won't crack when dropped, and it holds up against chemicals, extreme heat, cold, and UV exposure without going brittle over time. The feed lips are designed to resist creep, meaning you can store this magazine fully loaded for extended periods without worrying about the lips spreading and causing feed issues down the road.
Disassembly is straightforward thanks to ETS's proprietary baseplate design, making cleaning a non-issue. The ergonomically shaped floor plate is sized to give you a secure grip when pulling the mag from a pouch. The baseplate is also compatible with most aftermarket Glock floor plates, so customization is on the table if you want it.
This magazine is best suited for range use, training drills, and competition where higher capacity is an advantage. It comes backed by ETS Group's lifetime warranty, which adds real peace of mind for the price point.
Yes, this magazine is designed to fit both the Glock 43X and the Glock 48. Both pistols share the same magazine well dimensions, so the GLK-43X-19 seats and functions in either platform. It is not compatible with the original Glock 43, which has a different, narrower magazine well.
The magazine uses a single-stack design at the top to fit the 43X and 48 magazine wells, then transitions to a double-stack configuration in the extended lower portion. This is the same staggered approach used in many extended compact pistol magazines and allows the extra capacity without requiring an oversized grip frame. The magazine will extend noticeably below the grip of the pistol.
ETS builds creep resistance directly into the feed lips and body, so the design is specifically intended to hold up to long-term storage while fully loaded. The advanced polymer construction resists the kind of deformation that causes feed lips to spread over time. That said, rotating your magazines periodically is always a good habit regardless of brand.
The floor plate on this magazine is compatible with most aftermarket Glock baseplates, which opens the door for further customization if you prefer a different profile or grip extension. The ETS proprietary baseplate also makes disassembly for cleaning quick and simple without needing specialized tools.
The GLK-43X-19 is a great fit for range training, competition shooting, and high-volume practice sessions where fewer reloads means more time on target. The clear body makes it especially handy during drills since you can track your round count instantly. It is a popular choice as a range backup or training companion alongside standard-capacity factory magazines.
ETS Group backs all of their magazines with a lifetime warranty. If you ever have an issue with the magazine due to a defect in materials or workmanship, ETS covers it. This is one of the stronger warranty commitments in the aftermarket magazine space and adds meaningful value at this price point.
