Who This Is For
These sights are purpose-built for Glock 42, 43, 43X, and 48 owners who run a suppressor, plan to co-witness with a Trijicon RMR, or simply want a bombproof tritium night sight upgrade for concealed carry and home defense. If you need a sight that works at 3 AM as reliably as it does at noon on the range, this is it.

Frequently Asked Questions
Will these sights work with a Trijicon RMR or other red dot optic on my Glock?
Yes. The elevated suppressor height profile allows these sights to co-witness through the window of a Trijicon RMR and many other similarly mounted miniature red dot sights. They function as reliable backup iron sights so you always have an aiming solution, even if your optic fails or runs out of battery.
Do these sights fit the Glock 43X and Glock 48, or only the Glock 42?
These Trijicon suppressor height sights are confirmed compatible with the Glock 42, 43, 43X, and 48. All four pistols share a common sight footprint, so a single set of these sights fits each platform without modification beyond standard installation.
How long will the tritium lamps stay bright, and what does the warranty cover?
Tritium has a natural half-life of approximately 12 years, meaning lamp brightness will gradually decrease over time. Trijicon backs the green lamps in this set with a 12-year warranty from the date of manufacture, covering defects in materials and workmanship. The sapphire jewel and aluminum sleeve construction also protect the lamps from the rigors of daily carry and heavy range use.
