The first of the new Revolution series 1911 pistols from SIGARMS features all stainless steel frame and slide machined to exacting tolerances and hand-fitted to insure reliability and performance. Like all SIGARMS products the new Revolution contains only premium internal parts including a match grade barrel, hammer/sear set and trigger. The slide sports NovakŪ night sights. The frame features 20-line per inch checkering on the front strap as well as the mainspring housing and is complimented by a set of checkered custom wood grips. Both the frame and slide on the new GSR Revolution are de-horned making the pistol the perfect full-size carry gun. For safety the GSR features a beavertail grip safety with speed bump, extended thumb safety, firing pin safety and hammer intercept notch.
