The Ruger 57 Pro utilizes Ruger's safe, reliable, and proven Secure Action fire-control system that combines a protected internal hammer with a bladed-safety trigger. The trigger has a short, smooth pull, clean break, and positive reset. Impressive ergonomics include an easy trigger reach, high-performance glass-filled nylon grip, robust slide release, and reversible magazine release latch. The alloy steel barrel features a black nitride treatment for wear resistance.
