The Trijicon 600999 HD XR night sight set brings reliable low-light shooting to your FN 509, combining proven tritium technology with high-visibility aiming points. This green tritium front sight features a distinctive yellow outline that catches ambient light and stands out in dim conditions—exactly what you need for home defense, duty carry, or range work when daylight fades. Pair that with the matching green tritium rear sight, and you get a sight picture that remains visible in near-total darkness without batteries or electronics to fail.
Trijicon's HD XR sights are built tough for everyday carry and combat use. The black frame ensures durability and blends seamlessly with most modern pistols. Unlike basic fiber-optic or standard night sights, tritium glows continuously, making these sights reliable for the 2 a.m. scenario or low-light range sessions. The green-and-green sight picture is fast to acquire and easy to track under stress.
If you shoot an FN 509 and want sights that actually work when it's dark, the Trijicon HD XR set removes the guess from low-light aiming. These sights are designed to fit your platform without modification and to hold zero through years of draw practice and live fire.
