Sig Sauer Electro-Optics X-RAY3 Day/Night Pistol Sight Set - #8 Front / #8 Rear Round Notch Tritium

The Sig Sauer Electro-Optics X-RAY3 is a day/night pistol sight set built around Sig Sauer's 3-dot tritium illumination system. The tritium capsules glow brightly in low-light conditions and remain a clean, bright white under daylight, eliminating the need to swap sights based on ambient lighting.

This configuration pairs a #8 height front sight with a #8 height rear sight featuring a round (U) notch. The front sight uses a high-contrast green tritium vial with a white outline, while the rear is blacked-out to maximize visual contrast against the front post. This is the standard sight configuration found on the Sig Legion Series pistols and serves as a popular upgrade for many Sig Sauer P-series pistols.

Built for hard use, the X-RAY3 set pairs a steel rear blade with an oversized chemical-resistant polymer front module. Sig torture-tests the system to 20,000 rounds, and the tritium carries a 12-year half-life for long-term reliability. Whether replacing worn factory sights or upgrading a P-series carry gun, the X-RAY3 is a direct-fit, duty-grade solution for round-the-clock shooting.
