From pictures, it looks like the Wiley Clapp has the same Novak drift out/in front sight as the Match Champion. Is that true?
I installed a tritium white-outline Novak on my MC and it's good. I also bought a brass bead version just because. Now they are offering tritium with orange and yellow outlines -- tempting but probably getting a little OCD to replace.

I've seen from some folks on PF that Dawson Precision Novak-cut fronts work, too.
