Smith & Wesson 14457 Csx 15+1 9Mm Black

The Smith & Wesson CSX 15+1 9mm magazine is built for shooters who demand reliable capacity and control in a compact, metal-framed platform. Whether you're at the range, in competition, or carrying daily, this magazine delivers the round count and durability you need in a 9mm that doesn't sacrifice ergonomics for compactness. The CSX magazine line represents S&W's focus on shootable, controllable firearms—and the magazine engineering backs that promise.

What sets this magazine apart is its oversized wrap-around front strap, which increases textured grip surface by 200% compared to the original CSX design. That extra real estate means your hand has more to work with when you're managing recoil, executing rapid fire, or simply drawing from concealment. The steel construction and anti-tilt polymer follower ensure smooth feeding and consistent performance through thousands of rounds, while side-facing witness holes let you verify your load count at a glance—no guessing whether you're at 10, 12, or 15.

If you run a CSX or are considering one, having a spare magazine (or several) isn't optional—it's part of the platform. Reload faster, train harder, and build redundancy into your carry or duty rotation. This is the magazine S&W engineered specifically for the CSX platform; trust it to feed when it matters.
