I have Trijicon H3 sights on my pistol, and they were installed in '97. I understand that these sights lose their glow in about 12 years, and need replacing. How does one go about getting the glowy things replaced?
If you have a Glock, it's pretty easy to replace the sights. The sights don't go dark after twelve years; the half-life of tritium is something just over 12 years.
