The Trijicon HD Night Sight Set for S & W M & P C. O.R. E. is a high-visibility, heavy-duty iron sight platform built for tactical operators and everyday carry configurations utilizing Smith & Wesson M & P C. O.R. E. and M & P M2.0 Optics Ready slides. Forged from robust steel, this battery-free three-dot target acquisition system uses self-luminous green tritium lamps cushioned in shock-absorbing silicone rubber to guarantee constant sight alignment in total darkness. The front sight post features an aggressive photoluminescent orange paint ring that isolates focus onto the front blade during rapid daylight transitions. To ensure a clean, distraction-free target frame, the rear sight relies on a wide "U" notch with a blacked-out face that cuts down on glare. Additionally, the rear housing is built with a steeply hooked forward shelf to accommodate single-handed emergency slide racking against rigid surfaces.
