The Sig Sauer X-Ray3 Day/Night Sight Set (brand part no. SOX10001) pairs a green tritium, green-outline front sight with a green tritium rear sight, mounting via standard Sig Sauer front and rear dovetail cuts. Sig Sauer 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, and steel surrounds each tritium vial to shield it from recoil, cleaning solvents, and the elements. The set uses Sig Sauer’s standard #6 front and square-notched #8 rear sight sizing.
