This Ruger-57 is a 2020-production, USA-made, full-size 5.7x28mm pistol configured with a 4.94 inch black-nitride treated alloy steel barrel, a black-oxide slide, and fiber-optic/adjustable sights. It comes with six factory 20-round magazines and a tan soft pistol case, offering a complete setup in excellent condition.
The pistol uses a delayed blowback system with an internal hammer for smooth operation. Safety features include an ambidextrous manual safety and a trigger safety blade. The left-side magazine release and textured polymer grip with Ruger logo provide straightforward, positive handling. A frame marking indicates the pistol will fire with the magazine removed (no magazine disconnect).
The slide includes front and rear cocking serrations and a top lightening window, balancing manipulation and weight.

A Picatinny-style accessory rail on the dust cover supports common weapon-mounted lights or accessories.
The 4.94 inch barrel features a 1:9 twist to stabilize 5.7x28mm projectiles, and the pistol carries a standard 20+1 capacity. Overall length is approximately 8.65 inches with an unloaded weight of about 24.5 oz, keeping this full-size platform light and easy to carry on the range. Manufacturer part number is 16401.
