Built around the high-velocity 5.7x28mm cartridge, this full-size Ruger-57 pairs a 20+1 capacity with an internal-hammer, single-action fire control for a consistent trigger pull. The standard manual-safety configuration provides ambidextrous thumb safeties, supported by a trigger safety and internal passive safeties.
The 4.94 in alloy-steel barrel wears a black-nitride finish, and the through-hardened steel slide adds front and rear serrations for positive manipulation. A top lightening window in the slide reduces reciprocating mass while maintaining the pistol’s clean, black finish.
Ruger’s glass-filled nylon grip frame keeps weight down and durability high, while the anodized aluminum receiver/fire-control housing anchors the operating parts. An integral Picatinny-style accessory rail with multiple slots offers straightforward mounting for compatible lights or other rail-mounted accessories.
Sight regulation is simple and precise thanks to a green fiber-optic front and a fully adjustable rear with windage and elevation screws. The rear sight’s serrated square-notch face helps reduce glare for a crisp sight picture.
