The SIG Sauer P320 AXG Legion combines the modular P320 platform with an aluminum AXG grip module, Hogue Custom G10 grip panels, and a factory-installed magwell. Chambered in 9mm, it features a 3.9-inch barrel and a two-port slide-integrated expansion chamber designed to reduce felt recoil. The optic-ready slide includes enhanced serrations, while XRay3 Day/Night Sights provide a high-visibility aiming reference in changing light. Its XSeries Flat Skeletonized Trigger delivers a consistent, low-profile trigger interface, and the Legion Gray Cerakote finish adds durable surface protection.
