No, one coat of white from a fine tip paint pen (testors would also work) and then a coat of orange. The Dan Wesson has the tritium inset so it was easy to paint but the 229 has the clear coating flush with the sight blade so it looked ’blobby’. But it worked well. I eventually replaced it with fiber optic.
Man that was harder than expected to photograph!! This picture is about three years after I originally painted it; no reason to recoat.
