The Shield Arms S15 Gen 3 Flush-Fit Magazine is a patented, steel 15-round magazine designed for Glock® 43X and Glock® 48 pistols. Maintaining the same overall length as the OEM 10-round Glock magazine, the S15 delivers a 50% capacity increase in a flush-fit profile without sacrificing reliability.

The Gen 3 version brings multiple upgrades including a new US-based manufacturer, modular tooling, thicker steel, and a QPQ nitrocarburized black nitride finish for superior hardness, corrosion resistance, and durability. Raised ribs on the magazine spine ensure perfect OEM fit and alignment in the mag well.

Note: Use with a Shield Arms steel magazine catch is required for proper function and reliability.
