Mec-Gar S&W 659/5900/910/915 9mm Luger 20rd Blued Carbon Steel Magazine

The Mec-Gar MGSW5920B is a 20-round 9mm Luger detachable pistol magazine built for Smith & Wesson double-stack 9mm handguns. Made in Italy to Mec-Gar's tight tolerances, this magazine is a factory-grade replacement or spare for S&W 5900-series shooters.

This magazine fits the S&W 659, the 5900 Series, the 910, and the 915, covering a broad family of S&W double-stack 9mm pistols. The body is constructed from blued carbon steel, delivering durable feed geometry and a classic blued finish that matches factory pistol lines.

Inside, a high-impact polymer follower feeds reliably round after round, and the carbon-steel body is heat treated for long service life under repeated range use. The MGSW5920B delivers the precision manufacturing and capacity that S&W 659/5900/910/915 owners expect from Mec-Gar.
