My old eyes aren't as good as the used to be. I think having brighter colors on my sights may help. I have considered Truglo, etc and am not sure I want to spend that kind of money on several guns. Has anyone used this product from Bright Sights [/url]http://www.brightsights.com/index.shtml[/url]. Has it helped the sight picture? Is it durable, removable? Any other considerations I should look at? Any other paints you have used that maybe better?
