Trijicon HD XR™ Night Sights - Smith & Wesson M&P / SD9 / SD40

The Trijicon HD XR Night Sights SA637-C-600851 takes the proven HD night-sight platform and refines it specifically for shooters who need more precise target engagement at increased distances - built with the ever-evolving challenges of law enforcement in mind and delivering the next level of advanced target-identification capability beyond what standard HD sights provide.

The SA637-C-600851 fits Smith and Wesson M&P, M&;P M2.0, SD9 VE, and SD40 VE models - please note this sight set excludes M&;P Shield and C.O.R.E. models. The S&W M&P Shield Night Sights SA637-C-600851 purpose-built fit ensures correct dovetail installation and proper HD XR sight alignment on compatible platforms. Green tritium lamps are warranted for 12 years from the date of manufacture. Professional installation is recommended.

The defining feature of the Trijicon HD XR platform over standard HD sights is the thinner front sight post - a refinement that gives shooters a larger field of view around the front sight for better target visibility, faster target identification, and more precise shot placement at distances where a wider front post would obscure the aiming point. For law enforcement officers and defensive shooters who need to identify targets and place precise shots beyond typical close-range distances, the HD XR thinner post delivers a meaningful advantage without sacrificing the front sight prominence that makes the HD configuration faster than standard three-dot designs.

The Orange Night Sights SA637-C-600851 orange photoluminescent ring around the front tritium lamp maintains high-contrast front-sight visibility that draws the eye naturally under stress. Tritium Sights green illumination provides self-luminous performance in complete darkness without batteries.
