Shield Arms S15 Handgun Magazine Gen3 for Glock 43X & Glock 48 9mm Luger 15/rd

Designed with a patent-pending staggered round geometry, the S15 achieves higher capacity in the same footprint. The Gen3 model introduces improvements including a new US-based manufacturing process, modular tooling for simultaneous production of S15 and S10 magazines, and raised ribs to ensure precise fitment in the magazine well, reducing tolerance stacking from frame variations.

Constructed from thicker steel with a black nitrocarburized QPQ finish, the magazine offers enhanced corrosion resistance and durability. The QPQ Nitrocarburizing process forms a hard nitride layer on the metal surface, improving wear resistance and lifespan. Users should replace the OEM plastic magazine catch with Shield Arms steel mag catches to ensure reliable operation.
