Trijicon HD XR Night Sight Set for FN 509, Yellow Front Outline
This Trijicon HD XR set gives the FN 509 a yellow front outline and a narrow, 0.122-inch front post. Model FN604-C-600999 includes both the front sight and a matching U-notch rear, with green tritium illumination at all three dots.
The yellow ring provides a distinct daytime reference without changing the green color of the tritium lamps. The rear face is serrated and its lamp outlines remain black, keeping the colored front visually separate from the two rear dots. Sapphire lamp caps, protective aluminum sleeves, and silicone cushioning help protect the illumination system.
The FN 509 application is separate from the FNX-45/FNP-45 sets in the same family. This standard-height set is distinct from suppressor-height sights. Confirm the particular 509 slide configuration and any optic-clearance requirements before ordering, especially on Tactical or optics-ready variants.
