Wosport GB-37 Magazine Grip for Glock — TAN

The Wosport GB-37 is an extended grip with a spare magazine compartment that attaches directly to the frame rail of Glock G17, G18 and G19 pistols. It transforms the lower portion of the pistol into an enlarged grip area and keeps a spare magazine within reach without relying on external pouches.

The frame rail attachment requires no tools and is fully reversible: it mounts and removes quickly, making the GB-37 suited to both training and operational use when you want to increase your ammunition supply without adding bulk to the belt. The spare magazine sits inside the grip area, protected and readily accessible, but without a dedicated retention latch: retrieval is fast, while retention relies on friction and the geometry of the housing. Anyone looking for active retention with a mechanical lock should factor this in before choosing it for contexts with a high risk of impact or drops.

The two integrated side rails on the GB-37 body allow compact torches, laser sights or other rail-compatible accessories to be mounted without occupying the pistol's main frame rail. The contoured front grip area improves control during rapid fire, providing a tactile reference for the support hand.
