Mec-Gar USA
The Mec-Gar 15-Round 9mm Nickel Magazine for S&W 5900 Series Pistols is a reliable, high-capacity aftermarket mag built to feed your Smith & Wesson 5900-series duty or range gun. Mec-Gar has been making OEM magazines for decades—the kind that come factory in many firearms—so this is the real deal: professional-grade construction at a fraction of what you'd expect. If you carry or shoot a 915, 910, 659, or other 5900-series platform, this 15-rounder gives you serious capacity without the bulk of full-size pistol mags.
Built from heat-treated carbon steel, the tube is dimpled to lock onto standard Mec-Gar floorplates, springs, and followers—meaning you can swap components if you need to service it down the road. The spring is high-tensile music wire, the kind that holds tension reliably through thousands of rounds. Followers and floorplate are molded from high-impact polymer that won't crack or fail under hard use, and the floorplate sits flush with the frame so there's no snag when reholstering or drawing.
The nickel coating resists corrosion better than plain blued steel, which matters if you're in humid climates or running these mags hard. Whether you're setting up a spare mag pouch, building a rotation for the range, or keeping backups in your nightstand, Mec-Gar mags are the choice of shooters who don't compromise on reliability.
