The Sig Sauer 1911 proves that close tolerances equal complete reliability and need not be incompatible in an off-the-shelf pistol. Sig Sauer has introduced clean, distinct lines that American shooters have embraced, while retaining the crisp trigger pull, classic ergonomics, and exceptional accuracy they expect. The Traditional Tacops features: the recognizable round-top 1911 slide profile, front cocking serrations, a black Nitron finish, an ambidextrous safety, Magwell Ergo XT grips, and a M1913 accessory rail. Standard on all Traditional 1911 models are a match-grade barrel, flat mainspring housing, and a speed bump grip safety. Front straps have 25 LPI checking and the mainspring housing has 20 LPI for optimum grip and user comfort.
