TRUGLO TG131GT1 TFO Night Sights
The TruGlo TG131GT1 TFO Night Sight Set delivers a bright, three-dot sight picture for Glock pistols around the clock. The patented Tritium Fiber-Optic system combines Swiss tritium for low-light glow with green fiber-optic rods that gather ambient light during the day — no batteries required. CNC-machined steel bodies wear a durable Fortress protective finish, and the low-profile, snag-free design fits standard holsters. Compatible with Glock 17, 19, 22, 23, 26, 27, 34, 35, 45 and other non-M.O.S. models, this set is built for duty carry, concealed carry, and serious range work.

Best of both worldsI've run tritium sights and I've run fiber optic sights but this is the first time I've had both in one package and its a game changer. During the day the fiber optics are screaming bright like neon green bright and at night the tritium takes over and gives you a solid glowing dot without needing batteries or charging. The transition between lighting conditions is seamless, I tested them going from a bright outdoor bay into a dark indoor range and the sight picture never disappeared. Installed them on my G19 Gen 5 carry gun and the CNC machined steel housing is snag free on the draw from concealment. Had my gunsmith press them in since you need a sight pusher tool and he said the fitment was dead on. About 600 rounds in and they haven't shifted at all. If your still running stock Glock sights on a carry gun your doing yourself a disservice
Fiber optics are significantly brighter in daylight than tritium-only sights
Tritium element lasts for years without batteries or chargingThe green front and green rear can be hard to differentiate quickly, wish the rear was a different color

overpriced fiber optic sightsI 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.

Gives good sight pictureWhen 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 RemMax
