Description
The TruGlo TFO TG131GT1Y is a Tritium/Fiber Optic night sight set built specifically for Glock pistols in the popular “Low” dovetail profile. Designed around TruGlo’s original TFO (Tritium + Fiber-Optic) technology, the sights pair daylight-visible fiber optics with self-illuminating tritium capsules so the sight picture stays bright and intuitive from full sun to total darkness.
The green fiber-optic/tritium front sight draws the eye naturally for fast target acquisition, while the yellow fiber-optic/tritium rear sight delivers the high-contrast outline that has made TFO a long-running favorite among defensive, duty, and competition Glock shooters. Both elements are housed in rugged steel bodies finished in TruGlo’s signature Black Nitride Fortress coating for long-term corrosion and wear resistance.
This set fits Glock Low dovetail pistols across the 9mm Luger, 40 S&W, and 357 SIG family – including the 17, 17L, 19, 22, 23, 24, 26, 27, 33, 34, and 35. Installation is straightforward and only requires a standard sight-pusher tool, with no permanent gunsmithing required.
Whether you carry a duty Glock, run a competition G17 or G19, or just want fast target acquisition at the range and in the home, the TG131GT1Y delivers reliable day/night visibility in a compact, low-profile package trusted by shooters worldwide.
