Does anyone make replacement tritium tubes, or is it possible to get a whole new leaf and post?  Mine still glow, but it's not very strong.  I would like to bring the whole thing as close to it was at manufacture as possible (excluding its marks of character).  Thanks!

Short answer...no.

No one makes replacement sights for the Yugos, at least not direct replacements.  Abou the best solution is to install Merprolight or XS tritium sights, but then you loose the look of the originals.

I had fancied the thought of seeing if we could get a short run of vials from one of the manufacturers, but I honeestly don't think they would want to deal with it, or would charge us obscene prices to do it.

I was planning on using some glow in the dark paint to redo my night sites after I build and refinish my kit.  This is the type of paint I was thinking of using...
