Novak sights on a Model 19-3 or 28-2

[Lunker]

I recently shot the Wiley Clapp GP100 and have to say I was impressed with the quick target acquisition and potential for fast action shooting. It had Novak rear sights and a fiber optic front. I am interested though in getting a setup like that one one of my S&W revolvers. I have a Model 19-3 and a 28-2 that are both candidates, as neither is pristine.
Any thoughts on how I might go about it? Is there even enough meat in the S&W topstrap to put in a sight cut like the GP100 has? If it's too much of a hassle, I may have to suck it up and buy the Ruger.

Check the NOVAK site?

Ha, yes I did.
I should've mentioned that.

Someone said "its ok to own another brand" I'm quite fond of my gp100 though it's not the above model mentioned. There's room in the safe among the smiths for a nice ruger

Cylinder and Slide has a fixed sight replacement for adjustable sight S&W revolvers. Around $100
