Ruger 57 Pro | 5.7x28mm | 4.94″ Barrel | 2x20rd | 16403

The Ruger 57 Pro is a full-size semi-automatic pistol chambered in 5.7x28mm designed for fast, ergonomic handling and optics compatibility through a drilled-and-tapped slide. Its alloy steel, black-nitride barrel and serrated steel slide pair with a high-performance glass-filled nylon frame that includes a Picatinny-style rail. For an optic that pairs well without exceeding $1,000, consider a compact red-dot such as the Holosun 507C for fast target acquisition and proven durability.

This handgun suits precision-oriented target shooting and action-style competition where a lightweight, low-recoil cartridge and rapid sight acquisition are priorities.
