Ruger-57 5.7×28 mm Full-Size Pistol | Optic-Ready Slide, 20+1 Capacity, Black Oxide Finish
The Ruger-57 delivers high-velocity 5.7×28 mm performance in a lightweight, optic-ready platform.

The alloy-steel barrel features a 1:9-inch right-hand twist and a black-nitride finish for corrosion resistance. Forward and rear cocking serrations plus lightening cuts on the black-oxide slide aid manipulation and reduce reciprocating mass.
An optic-ready slide is drilled and tapped for mounting plates, giving you flexibility to add your preferred red-dot sight without gunsmithing. A green fiber-optic front sight and a fully adjustable serrated rear sight provide a clear sight picture out of the box.
The glass-filled nylon frame keeps weight down while offering aggressive molded texturing for a secure grip. A five-slot MIL-STD-1913 Picatinny rail accepts weapon lights or lasers, and the reversible magazine release accommodates left- or right-handed shooters.
Safety is comprehensive: ambidextrous manual safeties, a flat-bladed trigger with integral safety tab, an internal hammer catch, and a loaded-chamber inspection port. Tool-less takedown does not require a trigger pull, streamlining maintenance.
Introduced after Ruger’s safety retrofit range (serial prefix 644), this pistol embodies Ruger’s award-winning 2020 NASGW-POMA Best Overall New Product design while competing directly with the FN Five-seveN in the growing 5.7×28 mm market.
