The Strike Industries EMPG9&40 Enhanced Polymer Magazine Plate is a no-nonsense capacity booster for Glock 9mm and .40 S&W shooters who want more rounds on tap without swapping platforms. Snap one onto any OEM Glock magazine—it adds 6 rounds to G17 9mm mags and 5 rounds to G22 .40 cal mags—giving you the breathing room that counts in competition, defensive training, or high-round-count range days. Unlike flimsy knockoffs, Strike Industries engineered this extension plate with a reinforced steel locking mechanism that grips your magazine with a hook design, so it stays put under full loads and heavy use.

The polymer construction keeps weight down, and the textured grip surface means faster, more controlled reloads when seconds matter. The slow-drag, snag-free profile won't hang up on gear or holsters, and it plays nice with standard Glock mag geometries—no fitting or modification required. Whether you're running a G17 or G22, this plate gives you genuine extra capacity without the bulk of carrying spare mags.

Built for shooters who trust their gear and demand durability, the EMPG9&40 is the kind of straightforward upgrade that solves a real problem: more ammo, better grip, reliable construction. Black finish blends with any tactical setup.
