The better you can see your sights, the better you can shoot. We brought fiber-optics to the shooting sports industry decades ago for this very reason. TFO pairs our fiber-optic sights with our tritium night sights to create a consistently bright sight picture day or night! Our patented combination of tritium and fiber-optic technologies unites the best of both worlds providing the same bright sight picture whether you are in glaring daylight or complete darkness.Specifications:Finish/Color: GreenModel: Brite-SiteModel: Tritium/Fiber OpticType: SightFit: S&W M&PStyle: SquareColor: GreenFrame Material: SteelFirearm Fit: S&W M&PFirearm Type: HandgunFrame Color: BlackFront Material: Tritium/Fiber OpticFront Color: GreenRear Material: Tritium/Fiber OpticRear Color: Green
