ETS Group GLK-21-30 30-Round .45 ACP Clear Magazine for Glock 21/41

ETS Group 30-Round Extended Magazine – Glock 21 / 30 / 41 – .45 ACP

The ETS Group GLK-21-30 (UPC: 854094005652) is the ultimate capacity upgrade for .45 ACP Glock® enthusiasts. Designed for the Glock 21, but fully compatible with the G30, G36, and G41, this 30-round extended magazine offers massive firepower for home defense, range sessions, or PCC (Pistol Caliber Carbine) platforms that utilize Glock-pattern mags. Machined from ETS’s legendary advanced transparent polymer, this magazine provides instant visual verification of your round count and ammunition type, ensuring you are never caught off guard in a high-stress situation.

Engineered to survive the harshest environments, the ETS translucent body is chemically resistant to harsh cleaning solvents and UV rays, preventing the magazine from becoming brittle or yellowing over time. Its specialized polymer is also impact-resistant, meaning it won’t crack or shatter when dropped on concrete during rapid reload drills. Featuring a non-tilt follower and a heavy-duty stainless steel spring, the GLK-21-30 ensures reliable feeding even when loaded to full capacity. With its sleek, translucent design and legendary ETS durability, this magazine is a must-have for any .45 ACP shooter looking to push their platform to the limit in 2026.

Note: High-capacity magazine restrictions apply in several states (CA, CT, HI, IL, MD, MA, NJ, NY, OR, RI, WA). Please check your local and state laws before purchasing.
