The patented Shield Arms S15 Gen 3 is a flush-fitting 15-round steel magazine for Glock 43X/48, providing 50% more capacity than OEM 10-round magazines. The magazine features raised ribs on the back that fully match the OEM magazine position in the mag well, eliminating tolerance stacking from Glock frame variations, and comes with a new standard black nitrocarburized QPQ finish for high corrosion resistance. This increased capacity is achieved through patented magazine geometry that allows rounds to stagger, fitting more rounds in the same amount of space.
The magazine is equipped with a performance-enhanced steel spring and anti-tilt polymer follower for smooth, jam-free operation with most 9mm loads. Reinforced feed lips provide a super-secure fit and finish, ensuring reliable service. Made in USA with lifetime warranty and Spring for Life guarantee. The S15 Gen 3 represents a significant capacity upgrade for Glock 43X/48 owners seeking enhanced firepower while maintaining concealable flush-fit profile.
