Trijicon HD XR™ Night Sights - FN509 FN604-C-601000

The Trijicon HD XR Night Sights FN604-C-601000 brings next-level precision and target-identification capability to FN 509 owners, refining the proven HD platform with a thinner front sight post that delivers a larger field of view for better target visibility and more precise engagement at distances where standard HD sights are not fully optimized.

The FN604-C-601000 is designed specifically for the FN 509 sight configuration - a purpose-built fit that installs correctly and delivers proper HD XR sight alignment on this specific platform. The FN 509 Night Sight Set (FN604-C-601000) ensures proper dovetail installation and reliable HD XR performance on compatible FN 509 platforms. Green tritium lamps are warranted for 12 years from the date of manufacture. Professional installation is recommended.

The defining improvement of the Trijicon HD XR over standard HD sights is the thinner front sight post - delivering a larger field of view around the front sight that enhances the ability to identify targets, expedite engagements, and see the location of hits on target at longer distances. For FN 509 owners who carry and deploy their pistols in law enforcement and serious defensive applications where precise target identification and shot placement at extended distances matter, the HD XR delivers next-level capability built with the ever-evolving demands of law enforcement specifically in mind.

The Orange Front Night Sights FN604-C-601000 orange photoluminescent ring around the front tritium lamp maintains warm, high-contrast front-sight visibility that draws the eye naturally and immediately under stress, combining HD XR precision with the visual-priority advantage that orange front sights deliver in transitional and low-light conditions. Green tritium illumination provides self-luminous performance in complete darkness without batteries.
