ETS MAG Glock 21 .45 ACP 18-Round Magazine - Carbon Smoke Finish

The ETS MAG Glock 21 .45 ACP 18-round magazine is a high-capacity polymer alternative designed for shooters who want reliable feed without the weight and maintenance demands of steel. Built by Elite Tactical Systems Group, this carbon smoke-finished magazine holds 18 rounds of .45 ACP and fits Glock 21, 30, and 41 frames — making it a versatile choice whether you're running a full-size duty gun, a compact carry rig, or both. The translucent polymer body lets you track your round count and ammunition type at a glance, a practical feature when you're running drills, prepping for a match, or simply managing your gear in the field.

ETS engineered this magazine around real-world durability. The advanced polymer resists impact shock—it won't crack or shatter if dropped on concrete or stone like some of the older polymer designs you might remember. It handles extreme temperatures without becoming brittle, shrugs off harsh chemicals and UV exposure, and won't suffer from creep, meaning the feed lips and body stay true even when fully loaded and stored long-term. The specially designed base plate breaks down easily for cleaning, and the ergonomic floor plate is shaped to grab cleanly from mag pouches during reloads.

Compatible with Glock magazine extensions, the ETS MAG base is a platform, not a limitation. That flexibility, combined with the 18-round capacity in a .45 frame, gives you options for different mission profiles without buying a whole new magazine stack. Whether you're a competitive shooter, a working professional, or someone who just appreciates thoughtful design and American manufacturing, the carbon smoke finish complements both tactical and practical carry setups.
