What's in the Box Ruger-57 5.7x28mm Semi-Auto Pistol with Cerakote Gold Accents (2) 20 Round Steel Magazines Cable Lock Owner's Manual The Ruger-57 is a full-featured handgun wrapped around a standard capacity, 20-round steel magazine, chambered in the high performance and low-recoiling 5.7x28mm caliber. The most touted feature of this pistol is its impressive ergonomics. The slender steel magazine is surrounded by a glass-filled nylon frame featuring an optimized texture, making for a natural and ergonomic grip. Despite the longer cartridges, the trigger reach is no longer than many common 9mm Luger handguns. All of the controls are easily accessible, like the 1911-style ambidextrous manual safety, robust slide release and the reversible magazine latch. This version features Cerakote Gold Accents on Slide, Trigger, Mag Release, and Magazine Baseplate.
