I've painted the front sight of my 442 with the brightest orange nail polish I could find at WalMart. Put directly on the sight it was better than black but not very bright. Removed it with lacquer thinner, then painted the sight with white nail polish, and after that dried put the orange back on top of the white. Much brighter. Liked it so much I did the same to the front sights on my models 10 and 49.
