I found out recently that night sights have a half-life and certain colors (like orange) age faster than green. I have a 5-year-old green set of Trijicon's on my Glock 22 and I was quite happy with them. This is my "bedside gun" I can see where the gun is in the dark because the sights glow so nicely. But they seemed to have gone dim in the past few months. Really dim. You can still see them in pitch black, but they weren't glowing anymore. Trijicon does have a warranty and paid to ship my slide to them. But they soon sent me an estimate for the repair, about half the cost of replacement for them to refresh the sights with new reactive material. I pressed a little about this dullness being normal after only 5 years. I was told it was normal.
I did something a little clever and called into their sales line. Sales said they hold brightness for a long time, close to 12 years and that maybe if I was in Law Enforcement or military I might consider a rebuild at 9 years. I was told that I shouldn't see a decline after 5 years. I explained that my slide was in for repair and I was being told the opposite by the repair team.
And, after that, they repaired them at no charge. I still don't have the slide back. It's about a two-month process start to finish.
