As noted, each set of TRUGLO TG131GT1 TFO night sights is from the company's lauded "Bright-Sight Handgun" Series of sights. Billed as the ultimate handgun sights, these sights benefit from TRUGLO's patented TFO technology – a technology that represents a revolutionary innovation in the handgun night sights industry.

TFO is the name given to TRUGLO's patented combination of fiber optics and tritium technologies. For years, fiber optic inserts have been utilized in iron sights to increase visibility. The idea is that the optical fibers are positioned in such a way that ambient light shining upon the inserts is concentrated at the tip, making the dot of the sight brighter than its immediate surroundings and easier for shooters to see. These fiber optic inserts are used in conjunction with tritium illumination, which emits electrons through beta decay to produce a fluorescent light when mixed with phosphor materials. The result is a highly-visible dot that glows in the dark without the need for batteries or charging in light.

Each set of TRUGLO TG131GT1 TFO night sights is constructed from CNC-machined steel with a snag-resistant design that makes them perfect for use with concealed carry handguns. Also beneficial is the fact that the TFO technology is applied in such a way that the sights are concealed from targets, meaning you can see your target, but your night sights will not give away your position. As noted, they provide unbelievable transition through all lighting conditions, and are all but guaranteed to provide you with a better sight picture than your stock sights.

The TRUGLO TG131GT1 TFO night sights are compatible with each of the following GLOCK models: 17 17L, 19, 22, 23, 24, 26, 27, 33, 34, 35, 38 and 39. It is recommended that a gunsmith install these sights to avoid damaging either the sights themselves or the slide of your pistol, as specialized tools are required for proper fitting.

Must be old stock because it doesn’t work at all in low light. Go with a better quality product. Trijicon makes a great sight that works in total darkness. Very disappointed and will never use truglow products again. Nor will I order from here.

Excellent sights, and TFOs are significantly brighter than the more expensive TFX line.
Easy Install, Bright for my eyes!!

I originally ordered the All Green front/rear Sights but was accidentally sent the yellow rear green front sights. To be honest, I like the sight picture better with the contrast of the green/yellow!! For my eyes this works. Plus, they glow nicely at night!!
Best bang for the buck!!!!!
