The XS Sights R3D 2.0 Night Sights for Sig P320 (brand part number SI-R201P-6N) pair a tritium front sight with an orange outline against a serrated, glare-reducing rear sight. XS Sights widened the rear notch to 0.170 inch on the 2.0 generation, giving more visibility on either side of the front post for faster sight alignment, especially in low light. The rear tritium lamps run brighter than the original R3D version, and a black PVC ring surrounding them creates a more defined edge that keeps the front lamp from being confused with the rear under stress. Like every R3D sight, this set keeps the family’s signature ledge design, which aids one-handed manipulation of the slide.
