Description: Guns Listing ID: 683152 Pre-Owned Ruger-57 5.7x28mm Pistol with Original Case and Two 16-Round Magazines This pre-owned Ruger-57 is a semi-automatic pistol chambered in 5.7x28mm. It is part of Ruger’s modern centerfire handgun lineup and is designed around a lightweight, polymer-framed platform paired with a steel slide. This listing includes the original factory case and two 16-round magazines. The firearm is manufactured by Sturm, Ruger & Co., a U.S.-based firearms manufacturer known for producing a wide range of rifles, revolvers, and semi-automatic pistols. The Ruger-57 represents the company’s entry into the 5.7x28mm pistol category, a cartridge designed for high-velocity performance and flat trajectory characteristics relative to many traditional handgun calibers. The pistol is chambered in 5.7x28mm, a bottlenecked centerfire cartridge originally developed for use in compact firearm platforms. The cartridge is commonly noted for its high velocity and low recoil impulse compared to larger handgun calibers. Ammunition selection should always be based on manufacturer specifications and intended use, and users should verify compatibility with all ammunition types prior to use. The Ruger-57 operates using a delayed blowback action system. In this operating mechanism, the bolt and slide remain closed briefly upon firing to manage chamber pressure before cycling rearward to extract and eject the spent cartridge. This system is used in certain firearm designs to accommodate higher-pressure cartridges while maintaining controllable recoil characteristics. The pistol features a full-size polymer frame designed to reduce overall weight while maintaining structural rigidity. The grip is shaped to provide a full-hand purchase, supporting consistent control during handling and firing. The texturing on the grip surfaces is designed to assist with retention under a variety of conditions. The slide is constructed from alloy steel and includes front and rear serrations. These serrations provide additional contact surfaces for manual operation, including chambering, clearing, and administrative handling. The slide finish is intended to provide resistance to wear under normal use conditions. The Ruger-57 is equipped with adjustable rear sights and a high-visibility front sight system. Sight configurations may vary slightly depending on production year or configuration. The sighting system is designed to provide a standard alignment reference for target acquisition under varying lighting conditions. Many Ruger-57 models are configured with an optics-ready slide that allows for the mounting of compatible micro red-dot sights using an adapter plate system. Buyers should review listing photos and included specifications to confirm whether an optic plate or mounting hardware is present with this specific firearm. The pistol feeds from detachable box magazines. This listing includes two 16-round magazines, which are standard capacity for the Ruger-57 platform in many configurations. Magazine capacity may be subject to local, state, or federal regulations, and buyers are responsible for ensuring compliance with applicable laws in their jurisdiction. The Ruger-57 includes a manual safety system located on the frame. This safety mechanism is designed to allow the user to mechanically disable trigger operation when engaged. The presence and operation of the safety should be verified during inspection and handling. The frame incorporates an accessory rail located beneath the barrel, allowing for compatibility with select weapon-mounted lights or accessories. Compatibility varies depending on accessory manufacturer specifications. As a pre-owned firearm, this Ruger-57 may show signs of previous use. Cosmetic wear may include handling marks, finish wear, or minor surface imperfections consistent with normal operation and storage. Condition will vary depending on prior ownership history, and buyers should carefully review all provided photographs and condition descriptions. Routine maintenance for the Ruger-57 includes standard cleaning procedures such as barrel cleaning, slide lubrication, and inspection of the recoil system and magazine components. The firearm is designed for straightforward field stripping without specialized tools, allowing for routine maintenance and inspection. Proper maintenance practices, including regular cleaning and lubrication, help ensure continued reliability and service life. Users should consult the manufacturer’s manual for detailed instructions on disassembly, reassembly, and maintenance procedures. The Ruger-57 platform is designed to provide compatibility with the 5.7x28mm cartridge in a lightweight, full-size handgun configuration. Its design emphasizes controllability, modularity, and compatibility with modern accessories and optics systems.
