When you need to make a fast and accurate shot, brightness counts. TruGlo brought fiber-optics to the shooting sports industry years ago for this very reason. They have now paired them with their tritium night sights to create a consistently bright sight picture–day or night! Their 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.
These night sights are for Glock models 17,17L,19,22,23,24,25,26,27,33,34,35,38 and 39.
