The Ruger-57 is a semi-automatic pistol chambered in 5.7x28mm FN and built around Ruger's Secure Action fire-control system. Its 4.94-inch alloy steel barrel uses a black nitride treatment for wear resistance, while the through-hardened billet steel slide features lightening cuts and is drilled and tapped for mounting a compatible optic. The textured glass-filled nylon frame provides a secure grip, and the Picatinny-style accessory rail supports lights and lasers. A 1911-style ambidextrous manual safety, bladed trigger safety, lightweight firing pin, neutrally balanced sear, and hammer catch provide multiple layers of passive and active safety. The pistol offers a 20+1 capacity and includes a reversible magazine release for adaptable handling.
