TFO gun sights use the same proven technology as Truglo's TFO archery pins. These sights are the most revolutionary innovation since TRUGLO, Inc. introduced fiber optics. TFO refers to their patented combination of Tritium and Fiber Optic technologies. The Tritium maintains the brightness level of the sight in low-light (or NO light) conditions. That means you can see your sight even in complete darkness—with perfect transition through all lighting conditions. Tritium does not need batteries and does not need to be charged with light—it simply glows! Tritium / Fiber Optic Technology — The Best of Both Worlds! TFO HANDGUN SERIES TRITIUM / FIBER OPTIC The ultimate handgun sight. Uses our patented TFO technology. Unbelievable transition through all light conditions. Glows in the dark. CNC-machined steel construction. Concealed fiber cannot be seen by target. Fits standard holsters. Snag-resistant design. Have daylight fiber optic performance and nightsights for low light conditions in one package! thank you, Michael J.
