Trijicon HD XR Night Sight-Orange FN601-C-600881

The FNS-40, FNX-40, and FNP-40 are capable duty and defensive pistols built around the .40 SW cartridge - and the Trijicon HD XR Night Sights FN601-C-600881 gives FN .40 caliber owners a night sight upgrade that addresses the precision limitation that standard front posts create at distance. The HD XR was developed specifically around the demands of law enforcement - where target identification at extended distances and precise shot placement under pressure are requirements, not preferences.

The FN601-C-600881 is purpose-built for the FN America FNS-40, FNX-40, and FNP-40 - a sight dimensioned correctly for the FN .40 dovetail configuration to install cleanly and align precisely on these specific platforms. Every Trijicon HD XR Night Sights set is engineered for a specific handgun configuration, and the FN601-C-600881 reflects that same precision approach for compatible FN .40 models. Green Tritium Sights lamps are warranted for 12 years from the date of manufacture. Professional installation is recommended.

Standard night sights - even quality ones - have a front post wide enough to obstruct meaningful portions of the target area when engagement distances extend beyond close range. The Trijicon HD XR addresses this directly with a thinner front post that opens the field of view around the aiming point — giving FN .40 owners cleaner target visibility, faster target identification, and better ability to place precise shots and confirm hit location at distances where a wider post starts working against the shooter rather than for them.

The Orange Night Sight FN601-C-600881 warm-orange photoluminescent ring creates high-contrast front-sight visibility that draws the eye immediately and naturally under stress. The sight picture comes together fast in transitional lighting and stays reliable in complete darkness through tritium illumination that requires no batteries.
