The Ruger-57 standard model (16401) pairs a 4.94 in alloy-steel barrel with a through-hardened alloy-steel slide finished in black oxide. The slide includes front and rear serrations, lightening cuts, and a top window for weight reduction, with a measured slide width of 1.20 in. The platform delivers a 20+1 capacity in 5.7x28mm while keeping weight to 24.5 oz.
Sight regulation is straightforward thanks to a green fiber-optic front sight and a fully adjustable rear sight with windage and elevation screws. The rear blade has a serrated face to reduce glare, supporting a clear sight picture.
This semi-automatic, single-action design uses an internal hammer and incorporates multiple safeties: an ambidextrous manual thumb safety, a trigger safety, and internal passive safeties. Field maintenance is simplified by tool-less takedown.
The black, glass-filled nylon (polymer) frame features textured polymer grips with the Ruger phoenix logo and an integral Picatinny-style accessory rail. It uses 8-groove rifling with a 1:9" RH twist and a black nitride barrel finish. Made in the USA, this example includes two 20-round magazines, and the case label confirms model 16401.
