I have Tritium night sights of various brands on several of my handguns. These sights include Meprolight Night Sights on my CZ, and Trujicons on several of my .45 1911s.
If I am not mistaken, the element Tritium, which is the active substance providing radioactive illumination to these night sights, has a half-life of about 8 years. Thus in 8 years or so I am imagining that the sights would dim by about 50%
One might think that this means that around every 10 years or so the sights would need to have the Tritium replenished. (?)
If this is so, my question is -- what is the process for doing this? Do the sights have to be physically removed and replaced, i.e. by a gunsmith, or is there a way to replenish the Tritium with the sights in place.
I would appreciate knowing the answer to this question.
