Shield Arms S15 Gen 3 Magazine for Glock 43X/48, Black Nickel

Introducing the Shield Arms S15 magazine, a masterstroke of engineering designed specifically for the Glock 43X and Glock 48. This innovative piece offers a substantial upgrade in firepower without compromising on size or reliability—hallmarks of the Glock name.

The S15 is crafted from robust steel and ingeniously fits flush with your pistol's frame, maintaining the same length as an OEM Glock 10-round magazine while boasting an impressive capacity of 15 rounds. That’s a remarkable fifty percent increase in ammunition at your disposal, all within the same sleek profile.

This feat is achieved through Shield Arms' patent-pending magazine geometry that allows for staggered rounds, optimizing space efficiency without sacrificing dependability. The result? Uncompromising performance each time you chamber a round.

Proudly manufactured in the USA, this third-generation model introduces several enhancements: now produced by a new US-based manufacturer with modular tooling capabilities to craft both S15 and S10 magazines simultaneously. Raised ribs on its back ensure perfect alignment within your mag well, eliminating tolerance issues caused by variations in Glock frames.

Furthermore, this iteration features advanced materials—a tougher grade of steel treated with cutting-edge heat processes—and finished with black nitrocarburized QPQ coating for superior corrosion resistance. These improvements combine to deliver not only durability but also enduring reliability under demanding conditions.
