The XFULL series is Sig Sauer's premier 1911 that blends classic style with the best of modern features. The pistol features a railed frame for mounting lights and lasers along with an optic cut slide for direct-mounting of red dots that allow for direct co-witness with standard-height sights. The pistol also features an adjustable flatblade-style trigger and ambidextrous safety. Each pistol comes with G10 grip panels designed by LOK Grips along with a removable magwell extension. This package includes Sig Sauer's new Romeo X Compact series red dot that features motion activated illumination technology and a 20,000-hour battery life with a side load battery compartment. The sight is paired with Sig Sauer's P-Series XRay3 Day/Night iron sights. This model is chambered in .45 ACP and includes two 8-round magazines. The slide is compatible with red dot sights matching the RMSc optic footprint.
