replace lamp in night sights - Glock

[sigfan91]

I have a Glock with night sights. Both front and rear are dim. Where do I send it to get them replaced? Trijicon will replace the lamps in their sights for a reasonable price but I'm not sure who made these Glock sights.

Meprolite produces the tritium vials.
How old is your Glock? I think the sights are warrantied for 15 years.

I bought this gun used from another calgunner. I believe this was from 2003. The night sights still glow, just faint.

Try giving Glock a call regardless.
They may just have you send the slide in you never know.
Can't hurt to ask it's only a phone call.
Post up your results

Oops, I just remembered that the night sights in my Sig P230 is completely dead. Now I have 2 sets to re-lamp and I don't even know who makes the sights for P230.

Well...I emailed Glock about the dim sights on my G36 about 10 days ago. No replies yet.

However, I found out my Sig P230 was never offered by the factory with night sights. The sights were custom made. I contacted Trijicon. Very prompt replies. I sent some pictures of the sights to Trijicon and they said those were theirs, and can be re-lamped for $57.

I also found out ToolTech is Trijicon's custom shop. Custom P230 sights is listed at $280.

Tritium half lives every 12 years (so basically they *should* hold their original glow for 12 years)... sounds like they're older than that, if just barely.

yup, half live decay is 12.32 years...

so warrantied for 15 as suggested above is just silly.

I have factory Glock night sights on my 22 (rebranded Meprolites) as well... factory installed. I don't recall anything about a warranty on them at all honestly.

Manufacturing date should be stamped on the sights. This should give you an idea of how old they are.

Half life of 12 years just means the sights should glow half as bright when they are around 12 years old. In another 12 years or so they'll be 1/4 the brightness of original, half of that when they were 12 years old.

These sights seem to be less than 1/2 the brightness of the original sights.

The sights on my P230 (from 1993 with custom tritium sights added later) are completely dead. Theoretically these should be better than 1/4 brightness of the original sights.

At least that's how I interpret them...

I'll look more closely tonight, with magnifying glass and bright lights. Maybe some macro photos to see if I might have missed anything.

I just realized not everyone stamps their sights. You may never know how old they REALLY are.

At 12 years you will have HALF of the energy that was available when new. Therefore the light would in theory look to be half of what it was when new. The problem here is that the eye's response to lowering light levels is not linear.

you're right, somehow I think I already knew that
