ETS Glock 21/30/41 18-Round .45 ACP Clear Polymer Magazine

ETS Group builds this pistol magazine (part no. GLK-21-18) for the Glock 21, 30, and 41 (excluding Short Frame models), chambered in .45 ACP and extended to an 18-round capacity in a translucent, extreme-impact-resistant advanced polymer body. The polymer resists heat, cold, and UV exposure and is creep resistant, meaning the feed lips and body won’t spread even when the magazine is stored fully loaded for long periods. For Elite Tactical Systems Group owners of a Glock 21, 30, or 41 (non-SF), this handgun magazine is a durable, see-through, high-capacity spare.
