The ETS Group 27rd extended 9mm magazine for Glock brings competition-grade capacity and reliability to your duty, range, or match setup. Built from advanced polymer, this magazine feeds reliably through a wide range of Glock platforms—from the compact 26 to the full-size 17, plus the 19, 19X, 34, 45, and 18—and works across all generations (Gen 1 through Gen 5). Whether you're running a three-gun match, training at volume, or maximizing firepower on the line, the extra 27 rounds mean fewer mag changes and more time on target.
ETS engineered this magazine to withstand real-world use without compromise. The translucent polymer body lets you count rounds and verify ammo type at a glance—no guessing what's loaded. The feed lips and body resist creep and deformation even under long-term storage at full capacity, so your magazine stays reliable between range days. The material resists impact, harsh chemicals, UV exposure, and temperature extremes, staying functional in harsh environments and cold weather without becoming brittle. Drop it on concrete and it won't crack; that's the kind of durability competitive shooters and serious trainees demand.
The ergonomic floorplate is designed for fast reloads from mag pouches, and the baseplate disassembles easily for cleaning and maintenance. Most aftermarket Glock floor plates fit, so you can customize the setup to match your platform or preferences. This is a magazine built to run, not just sit in your safe.
