The Mec-Gar MGSW5915N is a 15-round 9mm magazine finished in black nickel, built with a heat-treated carbon steel tube. It combines a high-impact polymer follower with high-tensile music wire spring to ensure consistent feeding and reliable performance. The dimpled design accepts standard Mec-Gar floorplates, springs, and followers, while the high-impact polymer floorplate provides a flush fit with your pistol.
This magazine works with Smith & Wesson 5900 Series, 915, 910, and 659 pistols. Mec-Gar’s standing in the industry speaks for itself—major manufacturers including Browning, Remington, Sig Sauer, and Walther trust Mec-Gar to produce OEM magazines under their own brand names. As a steel magazine, it delivers the durability and precision fit shooters expect from a premium aftermarket magazine at an exceptional value.
