The TFX series of day/night sights features a 3-dot configuration with front and rear tritium illumination. The front sight features a white front focus lock ring which aids in front sight acquisition during normal daylight hours. The rear sight features a square notch style profile. The housing is made of high quality steel with a matte black finish. If you are concerned about your ability to make quality hits on target during a potential night time encounter then pick up yourself a set of the new TFX series sights from TruGlo. RSR -
