The ProMag Ruger-57 5.7x28mm 20-round steel magazine is purpose-built for shooters running Ruger's 5.7x28 platform. Built on a foundation of heat-treated high-carbon steel, this magazine combines traditional metalworking with modern polymer injection molding to deliver reliable feeding and long service life. Whether you're running drills at the range, training for defensive readiness, or just putting rounds downrange, having extra capacity on hand means fewer mag swaps and more time focused on your shot placement.
ProMag engineered this magazine with a heat-treated steel body paired with an injection-molded follower and a chrome-silicon wire spring—each component selected for durability under real-world use. The blue finish provides a clean look while the steel construction handles the pressures and wear that come with regular shooting. Made in the USA, this magazine backs your confidence with a lifetime guarantee against manufacturer's defects, so you can trust it to feed cleanly through magazine after magazine.
If you're building a Ruger-57 setup or rounding out your magazine rotation, the ProMag 20-rounder gives you the capacity and reliability that serious shooters expect without the guesswork. Simple, functional, and built to last.
