Maybe its that they are older, or maybe because they are the cheaper ones. But when I shot a night competition with Coach, I found that a temple indexed light (only 85lm) overpowered my tritium and I could no longer see the glow. I could see the paint, but not the glow any longer.
If I had to use my pistol in the dark against an absolutely 110% known bad guy they would work. But if I was lighting up the target (see rule 4) it wouldnt be any better than factory sights.
just food for thought based on what I have found.
That's actually not a problem. Didn't you notice that you got a really, really good sight picture that way?
Tritium sights are most useful when you don't need a light to identify your target with certainty, but it's too dark/dim to see your sights. I know some people thing this situation doesn't exist, but it's actually quite common. Go out on a night with a bright moon. You can see people's faces easily, but it's difficult or impossible for some people to see blacked-out iron sights because the light is so diffuse. Night sights, however, really shine! (pun intended). Parking lots and streets with certain types of lighting will produce the same situation. Plus there are plenty of times when you can identify with the light, then drop it and shoot two-handed using the night sights and get really good hits.
