When the standard factory Glock 43 capacity is simply not enough for your wants or needs, upgrade with XTech’s MTX +3 Glock 43 mag extension. This patented extension kit adds three rounds to create a 9-round capacity of popular 9MM ammunition for various uses. Attach it easily to the factory Glock 6-round mag with no special tools or processes. In one quick step, you are better equipped for defense, target shooting, or a day at the range. While Glocks are hugely popular, and the model 43 is a top-selling handgun, many users cite the small 6-round standard capacity as a downer. The XTech MTX +3 extension adds three critical rounds while maintaining a sleek and slim profile ideal for concealed carry in numerous configurations. Enhance your weapon’s overall ergonomics and control with a Glock 43 mag extension (plus 3) exclusively from XTech. This product combo is legal for shipping everywhere. We also offer a steel-reinforced 9-round Glock 43 extended magazine which can be found here.
