Trijicon HD Tritium Night Sight Set Features The Trijicon HD Tritium Night Sight Set uses a self-luminous three-dot night sight design built around a highly visible photoluminescent paint outline that performs equally well in bright daylight and low light. The 2x brighter domed sapphire and tritium front sight accelerates sight acquisition during a defensive draw giving shooters a clear fast reference point under stress. The rear sight s angled serrated U notch reduces glare from overhead or side lighting and helps keep the shooter s visual focus locked on the front sight rather than the rear. This combination of front and rear sight design reflects years of input from law enforcement and competitive shooters who depend on consistent performance in any light. Built specifically to fit the Smith and Wesson M&P C.O.R.E. and M&P M2.0 Optics Ready models the sight set installs into the factory dovetails without requiring any modification to the slide. The green tritium with yellow outline front paired with the green tritium and black outline rear gives shooters a distinct high-contrast sight picture that is easy to index quickly. Machined from steel with a black finish the sights are built to resist the wear and impact of daily carry and holster use. For M&P C.O.R.E. and M2.0 Optics Ready owners who want a dependable high-visibility sight upgrade for personal protection or duty use the Trijicon HD set delivers proven performance.
