The Ruger-57’s operating system is a semi-automatic, delayed-blowback design distinct from typical tilting-barrel systems. Its 1:9 RH twist alloy steel barrel carries a durable black nitride finish, paired with a black oxide slide that incorporates lightening cuts, an open-top window, and front and rear serrations for confident manipulation.
The full-size frame is molded from glass-filled nylon for strength and low weight, finished in black, and fitted with textured polymer grips bearing the Ruger phoenix logo. Controls include a reversible push-button magazine release, an ambidextrous manual safety, and a trigger safety for additional assurance. An accessory rail on the frame provides space for compatible add-ons.
Sighting equipment consists of a high-visibility green fiber-optic front and a black, serrated, fully adjustable rear. The slide is drilled and tapped for an optic plate, giving the user mounting flexibility if desired.
Field service is streamlined by a tool-less takedown that requires no trigger pull. This pistol is marked Prescott, Arizona, USA, with country of origin listed as USA, and corresponds to Ruger’s manufacturer part number 16401. The serial range falls within Ruger’s published safety bulletin concerning the right safety lever.
