15-round magazines for Glock G43X and G48 models. The magazines feature a flush-fit, high-capacity design accomplished through the use of a steel-only frame compared to factory Glock magazines with the traditional double-frame design. The Gen 3 magazines are made entirely in the USA and feature spacing ribs on the rear of the magazine for better fit in G43X and G48 pistols along with a thicker steel body and a more durable finish for improved reliability. These magazines are not compatible with G43 models.
