The FNX-45 and FNP-45 are serious defensive and duty pistols that a significant number of serious shooters run suppressed, and standard-height sights that disappear behind the suppressor body are the immediate limitation that creates once the can goes on. The Trijicon Bright and Tough Suppressor Height Sights for FN 45 give FNX-45 and FNP-45 owners the elevated tritium night-sight solution that restores a proper three-dot sight picture over the suppressor body without compromising sight performance or reliability. The FNX 45 suppressor sight challenge is straightforward - the suppressor adds height between the muzzle and the shooter's line of sight, pushing standard sights below the visual plane needed for proper alignment. The Suppressor Height Sights elevated profile on the Trijicon Bright and Tough FN 45 set clears that added height cleanly, giving you a natural, properly aligned three-dot sight picture whether the suppressor is on or off the pistol. The suppressor-height configuration works equally well in both configurations without any compromise to the sight picture. The Tactical Iron Sights suppressor-height configuration is also compatible with use alongside the Trijicon RMR red dot sight - serving as backup iron sights that co-witness through the RMR window for a complete primary and backup aiming solution. For FNX-45 and FNP-45 owners running an RMR alongside their suppressor setup, these sights cover both functions simultaneously. The Trijicon Bright and Tough self-luminous tritium-phosphor lamps provide three-dot illumination in complete darkness without batteries or electronics. The Pistol Sight sapphire jewel caps protect each lamp and evenly distribute light output. Silicone rubber cushioning and aluminum cylinder protection handle heavy recoil through years of hard use. Green lamps are warranted for 12 years from the date of manufacture. Trijicon® Suppressor/Optic Height Sights - FNX-45, FNP-45 FN203-C-600942 in Front White Outline/green Tritum
