ETS Group 30-Round Extended 10mm Auto Pistol Magazine for Glock 20/29/40 - Clear Polymer

Running a Glock 20, 29, or 40 in 10mm? An ETS Group 30-round extended 10mm auto pistol magazine gives you serious capacity without sacrificing reliability. Built from advanced polymer, this clear-body mag holds three times the rounds of a standard flush-fit magazine—a real advantage on the range, in the field, or at the competition line. The translucent construction lets you glance down and see exactly how many rounds you've got left and what type of ammo is loaded, eliminating the guessing game between stages or during a long practice session.

ETS polymer magazines are engineered to handle the abuse real shooters dish out. The material resists impact damage, harsh chemicals, and temperature swings—whether you're shooting in desert heat, mountain cold, or storing them long-term in a garage. The feed lips and body are designed to resist creep, so your magazine stays reliable even when fully loaded and sitting in a pouch for months. The ergonomic floor plate is shaped to grab easily from a mag pouch, and the base plate is purpose-built for hassle-free disassembly and cleaning.

Because ETS engineered their mag base to play nicely with common Glock magazine extensions, you've got flexibility in how you configure your setup. Swap extensions, experiment with capacity and grip feel, and keep your magazines running the way you want them to run.
