We brought fiber optics to the shooting sports industry years ago for this very reason. We have paired them 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. Whether in glaring daylight or complete darkness, you can count on TFO(R) to provide a bright and reliable sight picture. Springfield XD Front - Green / Rear - Yellow Uses our patented technology The ultimate handgun sight Unbelievable transition through all light conditions Glows in the dark No batteries required CNC-machined steel construction Concealed fiber cannot be seen by target Fits standard holsters Snag-resistant design Please note: Yellow fiber-optics are intended to appear less bright than green to increase contrast between front and rear sights.
