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.

I am truly sorry that I blew money on these sights. They are essentially the same thing that comes on most pellet guns these days. The body is made better, but it holds old and not so durable or even useful technology. For the same price, you can get top of the line tritium sights that are nearly indestructible and glow in 100% darkness for over a decade.
When I bought my Glock17 I didn't really care for the sights that it came with so the simple solution was to have them replaced.
I had them replaced by a Glock Smith at a local Gun Show and had him put these sight TruGlo on
While I admittedly don't go shooting after dark I have been known to push the range hours a time or two and fire a bit well past dusk and with these TruGlo Sights on my gun I can still see my sights in low light since they absorb any light around them and direct it into the dots you see from behind them giving you clear view of your sights plus they provide a clean crisp sight picture in day time
Overall I've been quite pleased with these sights since I had them installed a few years ago and they still glow today like they did back then
Probably one of the best aftermarket accessories you can add to your Glock are these sights right here
