The Smith & Wesson CSX 9mm Luger magazine is the factory-standard OEM magazine for the CSX compact pistol, engineered to feed reliably through thousands of rounds. Lightweight and durable, this stainless steel magazine with black nitride finish delivers the capacity and dependability you need for self-defense, duty, or range work. Whether you're building a backup mag setup for your CSX or simply want spares in your range bag, this magazine pairs proven S&W engineering with practical everyday carry reliability.
The 12-round capacity balances magazine length with usable firepower, and the removable floorplate makes cleaning and maintenance straightforward. Round count indicators on the spine let you glance down and confirm your load at a glance—useful during training or when you're swapping mags in the field. The injection-molded follower and high-tensile spring are built to cycle through hot ammunition and thousands of dry-fire cycles without losing tension or predictability.
The included magazine sleeve improves grip and control, especially helpful for shooters who find flush-fitting mags uncomfortable during extended practice. If you run a CSX as an EDC piece or keep one at the bedside, running multiple magazines means you're never caught short and always have a fresh, reliable loader staged and ready.
