Beretta Night Sight Kit Features The Beretta Night Sight Kit is built around tritium gas filled lamps a self illuminating technology that requires no external light source or battery to glow in darkness. A sapphire front lens sits over the tritium vial focusing the emitted light for a brighter more visible sight picture at night compared to standard sight lenses. Sapphire is also chosen because it resists damage from the solvents commonly used in firearm cleaning and maintenance so the sight keeps its clarity over years of use. Beretta describes this sapphire enhanced tritium vial as one of the brightest in the industry giving low light shooters a meaningful visibility advantage. In daylight the lamps present as bright white outlined dots allowing the sights to function as a normal three dot sighting system when ambient light is plentiful. This dual function design means shooters are not sacrificing daytime usability to gain nighttime performance. The kit is specifically built for the 92FS and 96FS Vertec pistol variants ensuring a correct fit without modification to the slide. Because proper fitment and staking are required Beretta recommends installation by a professional gunsmith and the Beretta Night Sight Kit is available for sale at GrabAGun for Vertec owners upgrading their sight system.
