Self-illuminating vials in tested configurations

Night Fision's GLK002007YGW pairs a green tritium front sight with yellow outline against a green tritium rear with white outline. This combination provides contrast in near-total darkness while remaining visible in daylight. The Perfect Dot geometry—square front post and U-notch rear—delivers a repeatable sight picture without batteries.

Frequently asked questions

Can I install these sights myself, or do I need a gunsmith?

Night Fision sights require professional installation using proper sight pusher tools. Attempting removal or installation by hand risks damage to the slide. Most gunsmiths complete the job in 1–2 business days. TacticCAL can recommend local options in Sunnyvale.

How long do tritium vials stay bright?

Tritium sights maintain usable brightness for 10–12 years under normal storage. Brightness gradually declines over time; you'll notice a slow fade rather than sudden failure. Vials cannot be replaced individually—the entire sight must be swapped.
