The Sig Sauer X-RAY3 Pistol Sight (part no. SOX10005) uses SIG SAUER’s standard #6 front and rear square-notch sizing, so it fits a wide range of SIG pistols without custom fitting. A blacked-out rear and a high-contrast, oversized fluorescent polymer front dot make target acquisition intuitive in any light, and the steel housing protects the tritium vials from recoil, solvents, and the elements over a 12-year half-life.
