Mec-Gar MGG172003A Glock 17 20rd Extended 9mm Luger, Black Carbon Steel w/Black Floorplate

When your Glock 17 is your main carry or range gun, the Mec-Gar MGG172003A extended 20-round magazine gives you the capacity and reliability you need without compromise. Mec-Gar has been making magazines for military and law enforcement since 1965, and this 9mm Luger magazine carries that industrial pedigree into your holster. Built from heat-treated carbon steel with a black finish and polymer extension, it's designed to handle thousands of rounds without failure—the kind of durability that matters when you need to trust your gear.

The 20-round capacity means fewer mag changes on the range and extra reserve rounds when it counts. The anti-friction coating lets rounds feed smoothly, and the high-visibility green follower makes it easy to see your round count at a glance. The black floorplate and steel construction give it a clean, professional appearance that matches your pistol, while the polymer extension absorbs impact without damaging the magazine body or your firearm.

Whether you're running drills, training for duty, or just want a trusted spare mag in your range bag, this Mec-Gar holds the same engineering standards as the magazines supplied to professional armorers worldwide. It's not fancy—it's just built to work.
