The current configuration features a two-tone finish with a silver/gray slide and a black frame/controls. The slide is marked "SIG SAUER P320" and includes rear slide serrations for a consistent grasping surface.
Up top, it wears fixed 3-dot iron sights with a single light-colored dot on the front sight and two light-colored dots on the rear sight. This is a straightforward, durable sighting setup with no adjustments required.
