ETS Group GLK2130 30-Round Extended 45 ACP Clear Polymer Magazine for Glock 21/30/41

The ETS Group GLK2130 is a 30-round extended magazine for .45 ACP Glock platforms—a practical choice for shooters who want higher capacity without sacrificing reliability. Built from advanced polymer rather than metal, this magazine fits Glock 21, 30, and 41 pistols and brings some real advantages to the range, training, or defensive setup. If you run a Glock .45 and want more rounds downrange between reloads, or simply prefer transparent magazines so you can see your ammo count at a glance, this is worth a serious look.

The clear polymer construction does more than let you visually confirm your round count—it's engineered to handle the abuse that magazines take in the field. ETS polymer resists impact, chemicals, heat extremes, and UV exposure without becoming brittle or warping, which matters if your gear spends time in a truck bed, range bag, or duty belt. The magazine won't develop creep; the feed lips and body stay tight even when fully loaded and stored long-term, so you're not chasing feeding issues months later. And if you need to swap out the base plate or experiment with different Glock mag extensions, the ETS design disassembles easily and is compatible with a range of aftermarket base pads.

An ergonomic floor plate makes it genuinely easier to grab from a mag pouch—a small detail that matters when you're running drills or reloading under any pressure. Whether you're doing duty work, competition, or just prefer 30 rounds of .45 for range sessions, this magazine delivers straightforward function without fuss.
