The Ruger 5.7 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, 1911-style ambidextrous manual safety, robust slide release and reversible magazine release latch. The alloy steel barrel features a black nitride treatment for wear resistance.
