The Sig Sauer X-Ray3 Day/Night Sight Set (brand part no. SOX10009) is a suppressor-height, green tritium front and rear sight pair built to mount to Sig’s dovetail-cut front and rear sight channels. Sig Sauer Electro-Optics blacks out the rear notch while keeping the front sight high-contrast, so target acquisition stays intuitive and fast in any light. The 3-Dot tritium system glows for genuine low-light illumination and stays bright and white in daylight, so there is no swapping sights between day and night use, and steel surrounds each tritium vial to shield it from recoil, cleaning solvents, and the elements.
