I then did some searching and located several different paints made just for sights, including phosphorescent, but I have no experience with amy of these.
Can anyone give me some advice about choosing a paint that will be highly visible (in White or possibly Green or even Red)?
How effective is the "Glow in the Dark" paint I've found?
It's a cheap gun but I want to help him see the front sight better. He's an old ex-Russian and loves the old (or replica) Russian guns.

Thanks,
BD
