ETS Magazine Glock 21, 30, 41 45 ACP Polymer
The ETS Magazine for Glock 21, 30, and 41 in .45 ACP is a polymer alternative built for shooters who want reliable capacity and durability without the weight of steel. Available in 9, 13, 18, or 30-round configurations, this magazine lets you choose the capacity that fits your carry method, competition setup, or range day. Whether you're running a compact carry gun or a full-size duty pistol, ETS has a capacity for your mission.
Built from advanced polymer that won't crack or shatter when dropped, the ETS mag is engineered to handle the rough-and-tumble reality of the range, the field, or duty carry. The translucent body lets you see your round count and ammo type at a glance—a small detail that matters when you're managing your loadout. The feed lips and body are designed to resist creep, so your magazine stays true even when fully loaded and stored long term, keeping your rounds reliable when you need them.
ETS designed the base plate with actual use in mind: it's easy to disassemble for cleaning and maintenance, and the ergonomic floor plate is curved to grab quickly from mag pouches without fumbling. The polymer construction handles extreme temperatures, harsh chemicals, and UV exposure without becoming brittle or degrading—meaning this magazine will perform whether you're shooting in Arizona heat or a Dakota winter.
If you run Glock extensions for magazine extensions or base pads, the ETS mag base is built to be compatible with them, giving you flexibility in how you set up your kit.
