TruGlo TFO TG131GT2 Night Sight Set for Glock 20/21 High - Green Tritium/Fiber Optic - Black Nitride

The TruGlo TFO TG131GT2 is a front and rear night sight set built specifically for full-size and mid-size Glock pistols. TruGlo's signature Tritium + Fiber Optic (TFO) technology pairs self-illuminating tritium capsules with light-gathering fiber optics, giving the shooter a clear, glowing sight picture day or night without batteries or activation switches.

Both the front and rear sights carry green tritium and green fiber optic elements for matched brightness in low light, and the set ships in the high sight profile for a taller sight picture on carry and duty Glocks. The bodies are CNC-machined from steel and finished in a rugged Black Nitride Fortress coating for serious corrosion resistance under daily carry, duty, or home-defense use.

Configured as a direct-fit set for the Glock 20, 21, 29, 30, 31, 32, and 37, the TG131GT2 installs with a front post and rear dovetail mount, fits standard holsters, and uses a 0.060" fiber-optic diameter on a 1.0" front sight body. No custom slide work is required on compatible Glock pistols - drop it in and go.
