The Ruger-57 brings 5.7x28mm performance to a full-size semi-automatic pistol platform with a 20+1 round capacity in a glass-filled nylon frame that keeps weight at just 24.5 oz. The alloy steel slide is drilled and tapped for direct mounting of an optic adapter plate, making it compatible with a wide range of micro red dot footprints without a mill or gunsmith. A fiber optic front sight and fully adjustable rear sight provide precise iron sight alignment out of the box. The 1911-style ambidextrous manual safety, reversible magazine release, and robust slide release make for a well-rounded ergonomic package for range and carry use.
