When you need to make a fast and accurate shot brightness counts. We brought fiber-optics to the shooting sports industry years ago for this very reason. We have now 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 you are in glaring daylight or complete darkness you can count on TFO to provide a bright and reliable sight picture. – 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
