The Smith & Wesson M&P 5.7 Magazine is a 22-round, stainless steel magazine purpose-built for the M&P 5.7x28 pistol platform. If you've picked up an M&P 5.7 or are considering one for defensive carry, sport shooting, or range work, having reliable factory magazines on hand isn't optional—it's foundational. This mag delivers the capacity and durability you need to keep your shooting sessions productive and your carry gun ready.

Built from stainless steel, the M&P 5.7 magazine is engineered to handle repeated loading cycles and the rigors of regular use without premature wear or feeding issues. The 22-round capacity makes it the standard-size option for the M&P 5.7 platform, striking a practical balance between magazine bulk and firepower. Whether you're stocking up for the range, training for carry, or building a defensive battery, having multiple factory mags ensures you'll always have a loaded option ready.

Smith & Wesson magazines are designed to the same tolerances as the pistols they feed, so fit and function are predictable. That matters when reliability is non-negotiable. Pick up one or several—most shooters find they appreciate the flexibility of multiple mags and the peace of mind that comes with factory-backed components.
