57 5.7x28mm Fn 4.90in 20 + 1 Black Semi Auto Pistol - Optic Ready & Manual Safety

The Ruger 57 is a full-size semi-automatic pistol chambered in 5.7x28mm FN and finished in Cobalt Cerakote. Its ergonomic, textured glass-filled nylon frame provides a secure grip, while the Secure Action fire-control system combines an internal hammer with a bladed trigger safety. A 1911-style ambidextrous manual safety, reversible magazine release, and inspection port provide practical handling and status confirmation. The 4.9-inch barrel uses a black nitride treatment for wear resistance, and the slide is drilled and tapped for an optic adapter plate. Windage- and elevation-adjustable rear sights pair with a fiber optic front sight for rapid target acquisition. The pistol includes a Picatinny-style accessory rail and two 20-round magazines.
