anyone have their trijicon nite sites go dead?

[2002gti]

just wondering about how much life you got from them?

 

[Hard Ball]

No, but they do have a finite life. If they start looking dim replace them.

 

[Kevin Quinlan]

I think it about 15 years. The ones I put on my Glock are 19 years and going strong.

Tritium has a half-life of 12.3 years, meaning at the end of that time, it will have expended half of its radioactivity, and 12.3 yrs. after that, half of that half, and so on.

I had a set on my SA V10 Ultra that didn't last five years.

I've heard of some on higher recoiling guns going out sooner. The trit vials may shake loose or something. Or it just may be a defective set. Even after the "half-life" they aren't just supposed to turn off, just get progressively dimmer.

Had 2 pairs of meprolights go dim, but not my Trijicons....which are 3x as old.

NITE SITES dead

I read, somewhere that someoone contacted the night sight manufacturer and they replaced them free. It's worth a try.

I had Trijicon inserts installed on my Browning HP Mark II in 1986....they had noticibly dimmed about 7 years later and died entirely about 4 years after that....so make that approximately 11 years from when they were installed.
