The better you can see your sights, the better you can shoot. Truglo brought fiber-optics to the shooting sports industry decades ago for this very reason. TFO pairs Truglo's fiber-optic sights with Truglo's tritium night sights to create a consistently bright sight picture - day or night! Truglo's 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:Unmatched visibility in all shooting conditions 24/7Glows in the darkUtilizes quality Swiss tritium for maximum brightnessNo batteries requiredCNC-machined steelConcealed fiber can not be seen by targetSnag resistant designFits standard holstersFortress finish provides a permanent protective coating for maximum protection
