The Glock 43X and 48 are great carry guns — slim, reliable, and easy to shoot. The factory 10-round magazine makes sense for a lot of situations, but when you want more capacity for the range or competition, ETS steps in with this 19-round extended option that fits both platforms without any modifications to the pistol itself.
The body is built from ETS's advanced impact-resistant polymer, and the Carbon Smoke translucent finish does something standard Glock mags can't — you can actually see your remaining rounds and the type of ammo loaded at a glance. No more counting witness holes or guessing. The polymer is also engineered to resist heat, cold, UV exposure, and harsh chemicals, so it won't get brittle sitting in a range bag through summer heat or winter cold.
One of the more practical design details here is the creep resistance. The feed lips and mag body are built to hold their dimensions even when left fully loaded for extended periods — which is something that matters if you keep mags staged or prepped long term. The specially designed base plate makes disassembly tool-free for cleaning, and the ergonomic floor plate profile helps you pull the mag cleanly from a pouch on a fast reload. It's also compatible with standard Glock magazine extensions if you want to customize further.
This mag is a popular pick for 43X and 48 owners who shoot a lot at the range and want to spend less time reloading. It's made in the USA and backed by ETS's lifetime guarantee.
Yes, this magazine is designed to fit both the Glock 43X and the Glock 48. The two pistols share the same grip frame and magazine well, so the same mag runs in both. No modifications to the pistol are needed.
The standard factory magazine for the Glock 43X and 48 holds 10 rounds, so this ETS mag nearly doubles that capacity. It does extend below the grip, so it will add some length to the overall package — something to keep in mind if you're planning to use it for carry versus range or competition use.
ETS builds this magazine with creep resistance in mind, meaning the feed lips and body are engineered to hold their shape even when stored fully loaded over extended periods. This is a common concern with extended polymer mags, and ETS specifically addresses it in the design of this model.
Yes, the base plate is designed for tool-free removal, making it easy to field strip and clean the magazine internals. ETS designed the floor plate to pop off without any special tools, which keeps maintenance quick and straightforward after a range session.
The advanced polymer ETS uses is built to resist impact, UV exposure, extreme temperatures, and harsh chemicals. Real-world testing has shown the magazine body holds up well to repeated loading, dropping during drills, and general range abuse with minimal signs of wear.
Yes, this magazine is compatible with standard Glock magazine extensions, giving you some flexibility if you want to add grip length or further customize the setup. The ETS base plate also works within the ETS line of 9mm double-stack baseplates if you're already running other ETS accessories.
