The new Truglo Brite-Site TFO for GLOCK 41 and GLOCK 42 Model Handguns (Click Here to read a review and see the video on the GLOCK 41 and 42 Models) are low profile sight housings constructed from CNC-machined steel. The technical design protects the fiber while concealing its view from the target. The TFO sights fit in standard holsters and are designed to be snag-resistant and dependable. Each set is available in a green front sight /green rear sight combination or green front sight / yellow rear sight combination.

The new sights offer revolutionary innovation with TRUGLO’s patented combination of TFO (Tritium and Fiber-Optic) technology delivering an enhanced sight picture 24/7. Rapid target acquisition is achieved with TFO technology by utilizing existing ambient light to illuminate the sight picture during bright lighting conditions and then utilizing the tritium component to illuminate the fiber-optic during low light or no light conditions. The TFO technology offers an uninterrupted, consistent sight picture for the shooter when other sight systems fall short.
