Frequently Asked Questions
Can I use these sights as backup iron sights with a Trijicon RMR?
Yes. The suppressor height profile is specifically designed to co-witness with the Trijicon RMR and similar miniature red dot optics. When your optic fails or needs a battery change, these tritium iron sights provide an immediate, reliable aiming solution without needing to remove the optic.
Do these sights fit all Glock 42 models, and are they difficult to install?
These sights are compatible with the Glock 42 as well as the Glock 43, 43X, and 48, which share the same sight footprint. Installation requires a sight pusher tool or professional gunsmith, as the sights press-fit into the slide's dovetail. Attempting installation without the proper tool can damage the sight or slide finish.
How long do the tritium lamps last, and will they stay bright over time?
Trijicon warrants the green tritium lamps for 12 years from the date of manufacture. Tritium is a radioactive gas that naturally decays at roughly 5.5% per year, so brightness gradually diminishes over time — but remains functional well within the warranty period. The sapphire jewel lens and silicone-cushioned aluminum housing protect the lamps from recoil and impact throughout the sight's service life.
