The SIG Sauer 1911R-45-BSS-CA is a full-size 1911 pistol chambered in .45 ACP and configured for California compliance. Its stainless-steel frame and slide receive a Blue/Black Nitron finish, while the hand-fitted construction, match-grade barrel, and premium hammer, sear, and trigger components support consistent performance. Novak low-profile night sights provide a clear aiming reference in reduced light, and the integrated accessory rail supports compatible weapon lights and lasers. Custom checkered wood grips, front-strap checkering, and mainspring-housing checkering improve handling. A beavertail grip safety with speed bump, extended thumb safety, firing pin safety, and hammer intercept notch provide layered mechanical safety features.
