Description
The Shield Arms S15 Gen 3 is a flush-fitting steel magazine designed for the Glock® 43X and Glock® 48. It provides a 15-round capacity while maintaining the same overall length as the OEM Glock 10-round magazine by using Shield Arms’ patent-pending staggered geometry. Gen 3 updates include new US-based manufacturing, improved steel and coating, raised rear ribs to better align with OEM magazine position, and a black nitrocarburized / black nickel finish for enhanced corrosion resistance.
