The Mec-Gar MGSW5917B is a 17-round 9mm Luger magazine built for Smith & Wesson's classic duty and service pistols. Whether you're stocking backup mags for your 5900-series gun, 910, 915, or vintage 659, this Mec-Gar magazine delivers the capacity and reliability that have made the brand a standard-issue choice for law enforcement and military arsenals since 1965. Made in Italy using heat-treated, precision-stamped steel, these magazines are engineered to feed reliably through thousands of rounds without the premature wear or failures common in cheaper imports.
Mec-Gar's reputation rests on decades of manufacturing magazines for the world's largest firearm makers and militaries—not on marketing hype. Each magazine features strengthened feed lips that maintain their shape and grip, so rounds feed smoothly even after hard use or storage. The blued finish matches the steel frame pistols of that era and resists light corrosion in field conditions. At 17 rounds, you get genuine capacity without gimmicks or unreliable stacking.
This is the magazine choice when your gun's reliability matters. Whether you're running drills at the range, training for personal defense, or maintaining a trusted service pistol from decades past, Mec-Gar magazines are the aftermarket standard that gunsmiths, law enforcement, and serious shooters reach for first.
