Shield Arms Magazine, S15 Gen 3, 9MM, 15 Rounds, Nitride Finish, Black, For Glock 43X/48 SA-S15-BN-GEN3

You read that right; this is a 15-round magazine for the Glock 43X and Glock 48. Not only does it provide you with 50% more capacity, it does so in the same overall footprint! This patented 15-round steel magazine fits flush like the factory Glock magazine, thanks to Shield Arms’ patent-pending staggered magazine geometry. The steel receives a QPQ Nitrocarburizing surface treatment that increases hardness, wear, and corrosion resistance.
