The 1911 pistols from Sig Sauer feature all stainless steel frames and slides machined to exacting tolerances and hand-fitted to insure reliability and performance. Like all Sig Sauer products the 1911 contains only premium internal parts including a match grade barrel, hammer/sear set and trigger. The slide sports Novak night sights. The frame features 25-line per inch checkering on the front strap and 20-line per inch on the mainspring housing and is complimented by a set of checkered custom wood grips. Both the frame and slide on the 1911 are de-horned making it ideal for perfect full-size concealed carry. For safety the Sig Sauer 1911 features a beavertail grip safety with speed bump, extended thumb safety, firing pin safety and hammer intercept notch. Models are also available with an optional integrated accessory rail.
