FAB Defense FX-UMAGG17B Glock 17 9mm 18-Rd Polymer Magazine

The FAB Defense FX-UMAGG17B is a high-capacity 18-round polymer pistol magazine engineered for Glock 17 handguns chambered in 9mm Luger.

Built around a tough, lightweight polymer body finished in black, this extended magazine delivers reliable feeding while keeping carry weight to a minimum. It ships with two enclosed floor plates, a slim concealable base plate installed at the factory and an interchangeable tactical floor plate included in the box, so the user can swap profiles to suit duty, range, or concealed-carry use.

A visible round-count indicator lets the shooter check even-numbered rounds remaining at a glance without removing the magazine from the pistol. As a factory-pattern replacement, it drops into any standard Glock 17 magazine well and offers a straightforward bump in capacity over the standard 17-round factory Glock magazine.
