    Default Trijicon GL01 Cold Weather Tolerance

    I have a question, kind of a simple one. What are the temperature tolerances of the GL01 sights if there are any? I'm not totally familiar tritium sights and am curious if prolonged exposure to cold weather will affect them. Any help would be greatly appreciated.

    Ive had these on multiple Glocks and in temps below freezing/and above 100 degrees without any issues or problems...

    I blieve the half life if tritium is around 12 years if that matters to you

    Same here, no issues in inclement weather. Two Glocks had Trijicon, one had Meprolight. Never had a failure with any of them. And I don't baby them in the least.

    Just replaced two sets...dated 1991 and 1999. The 1991 set was so dim they were almost dark.

    So, you should budget regular sight replacement every 10-12 years or so.

    Bought the tool to service Glock sights, did a lengthy writeup elsewhere. Will repost here if anyone wants to see it. No surprises or rocket science.


    Glock 19 rear sight replacement in progress.


    New vs. old Tritium sights on a Glock 19. Old sights are about 1991-92 vintage. New sights less than 6 months old.
