About the Ruger-57
The Ruger-57 brings the 5.7x28mm cartridge into a full-size polymer pistol that weighs under 29 ounces and feeds from a 20-round magazine. The cartridge runs at low recoil with a flat trajectory, which keeps follow-up shots fast during range strings and makes the platform approachable for shooters who find 9mm snappy in lighter guns. Ruger's Secure Action trigger pairs a bladed safety with a short reset, the slide carries both front and rear serrations, and a manual thumb safety suits buyers who want an external lever. Steel magazines and an accessory rail round out the package.
