Novak sights: tritium vial life expectancy?

lrrifleman · Jan 19, 2025

I am contemplating putting a Novak sight on my Glock 30 Gen 4 because of the ability to adjust the sight . My question is, how long can you expect the tritium vials to work?

As always, thanks in advance for your help!

The half life of Tritium is 12.3 years. Most manufacturers of tritium sights guarantee them for 10 or 12 years.

Tritium sights are generally usable for 10-12 years.

They are "useable" forever; they lose most of their glow, however, in 10-12 years...

Once you have them, you will realize that is really not a big deal. Night sights make it very easy to spot your gun lying on a nightstand in the dark, but don't really do a heckuva lot to help you actually aim, except to keep the gun pointed in the correct general direction.
