Frequently Asked Questions
Will these sights work with a suppressor or threaded barrel on my Glock 20?
Yes. This set is specifically designed as suppressor-height sights, meaning the front and rear sights are tall enough to provide a clear sight picture even when a suppressor or compensator is mounted on your Glock 20's threaded barrel. They function equally well on standard, non-suppressed configurations.
How long will the tritium illumination last?
Trijicon tritium lamps have a rated service life of approximately 12 years, after which they will dim but the sights remain fully functional as standard iron sights during daylight. No batteries, charging, or activation is ever required — the tritium glows passively at all times.
Are these sights a direct drop-in fit for the Glock 20, and do I need a gunsmith to install them?
These sights are engineered specifically for the Glock 20 frame and use standard Glock dovetail dimensions for a precise fit. Many experienced owners install them at home using a sight pusher tool, though professional installation by a qualified gunsmith is always recommended to ensure proper seating and zero.
