Shadow Systems XR920 Combat Features The Shadow Systems XR920 Combat is chambered in 9mm and built on a semi-automatic action with a 15-round capacity giving shooters a substantial round count for duty or home defense scenarios. Its 4 spiral-fluted bronze barrel is both threaded and distinctively finished combining the ability to mount a suppressor or muzzle device with a visually striking contrast against the rest of the pistol. The optics-ready slide lets shooters mount a red dot sight of their choice speeding up target acquisition compared to iron sights alone. The slide s cut accommodates a range of common optic footprints giving shooters flexibility in choosing their preferred sighting system. Shadow Systems built the XR920 Combat as a full-size pistol intended for duty and serious defensive applications and the included green tritium sights provide a reliable point of reference in low-light conditions even without an optic mounted or powered on. The pistol s centerfire action and robust construction are designed to hold up to the demands of regular training and carry. A threaded barrel paired with the spiral bronze finish gives this XR920 a distinct look while retaining full functionality for suppressor use. For shooters who want a duty-capable optics-ready 9mm pistol with tritium-equipped iron sights as a backup the Shadow Systems XR920 Combat is available for sale at GrabAGun.
