Product Description
The Shield Arms S15 Gen 3 is a flush-fitting 15-round steel magazine designed for Glock 43X and Glock 48 pistols. Built to match the overall length of an OEM 10-round magazine, it delivers a 50% capacity increase without changing the footprint. Its patent-pending geometry allows rounds to stagger for higher capacity, while Gen 3 updates include improved manufacturing and materials, raised rear ribs to better match OEM magazine positioning, and updated steel and finishes for durability and corrosion resistance. Made in the USA.
