The Sig Sauer 1911 X-Series combines classic single-action 1911 operation with modern performance features. Its full-size stainless-steel frame and five-inch barrel provide a stable shooting platform, while the black DLC finish adds durable surface protection. The optics-ready slide accepts a compact direct-mount red dot footprint, and P-Series XRAY3 Day/Night sights provide a highly visible aiming reference in changing light. LOK Grips G10 panels, a checkered front strap, an undercut trigger guard, and a detachable metal magwell support confident handling. An adjustable flat-blade trigger and extended ambidextrous manual safety complete the competition-oriented configuration.
