Wosport GB-48 Magazine Holder for Glock 17/18/19 — Black

The Wosport GB-48 is a quick-access unit that attaches to the frame rail of Glock 17, 18 and 19 pistols, turning the grip area into a multi-function system: it houses a spare magazine inside the grip body and adds two side rails for accessory mounting, without any permanent modification to the weapon's internal structure.

The two side rails allow compact accessories — lights, lasers, grip tape — to be mounted directly to the sides of the frame, in positions that are normally inaccessible on a standard pistol. The shaped front area provides a positive purchase for the support hand, useful during reloads or when operating under stress. The main advantage is having a spare magazine immediately at hand, integrated into the body of the weapon itself: the trade-off is a noticeable increase in overall bulk and weight, which may be a drawback for those who prioritise a light or low-profile carry setup.

Compatibility is stated for Glock 17, 18 and 19 pistols: before purchasing, verify that your frame rail matches the standard specifications of the G series, as some aftermarket versions or replicas may have different tolerances.
