Description
The TRUGLO Tritium Pro (TG231G1W) is a low-profile steel night-sight set for Glock pistols. Both front and rear use green Swiss tritium capsules that glow without batteries or charging, while the front adds a white Focus-Lock ring so the eye locks on quickly in daylight. The U-notch rear has an angled front edge for one-handed slide manipulation. CNC-machined steel with TRUGLO’s Fortress Finish, assembled in the USA, and the low height fits standard holsters and keeps the factory sight radius. Fits Glock 17, 17L, 19, 22, 23, 24, 26, 27, 33, 34, 35, 38 and 39 including Gen5, but not MOS slides.

Frequently asked questions
Which Glocks does the low set fit?
Glock 17, 17L, 19, 22, 23, 24, 26, 27, 33, 34, 35, 38 and 39, including Gen5. MOS optic-cut slides need a different height.
How long does tritium glow?
Tritium capsules fade gradually over roughly 10 to 12 years and need no batteries or light charging.
Do I need a licence to buy pistol sights?
No. Sights are not licensed items; fitting usually requires a sight pusher or a gunsmith, which 3GT can arrange.
