ProMag SMIA24 9mm Luger 20-Rd Blued Steel Pistol Magazine for S&W CSX

The ProMag SMIA24 is a 20-round extended 9mm Luger detachable pistol magazine engineered specifically for the Smith & Wesson CSX pistol. Built to deliver extra capacity beyond the factory offerings, the SMIA24 keeps your CSX fed and ready for range sessions and training drills.

The magazine body is constructed from 4140 heat-treated steel for strength and long service life, finished in a corrosion-resistant black oxide (blued) coating that protects the surface and gives the magazine a clean, classic look. Inside, an injection-molded polymer follower and chrome silicon wire spring work together to provide smooth, reliable feeding round after round.

Designed as a direct-fit replacement magazine for the S&W CSX, this ProMag unit drops in just like a factory magazine and ships ready to use. Backed by ProMag's reputation for dependable aftermarket pistol magazines, the SMIA24 is a smart upgrade for any CSX owner looking for additional round capacity.
