I'm thinking about replacing the Trilux H3 night sights on my SW9C. They are looking dim now a days. Found these on Midway USA Meprolight Tru-Dot Sight Set S&W Sigma Steel Blue Tritium Green - MidwayUSA
they look good and the price is not bad either. Does anyone here have these? Are they any good?

I have a set of Tru Dots on my HK P7M8 and they are great sights and have stayed luminous for a long time. I like them so much I just bought a spare set to keep in stock, figuring some day they have to burn out.

Nice. Now I have to make sure those will work on my Sigma. I have the older Sigma, but it looks like it will work. On the front sight it looks like it will not be a problem. On the rear i'm not so sure.
