Yeah you'll need the slide milled for a novak and that will cost as much as half your pistol costs plus a trip to a smith. I'd get a Harrison retro sight (brownells) which will fit your rear dovetail and get any number of front night sites staked on. You'll keep the GI look but upgrade your sites for cheap. Forget the rear night site, practice a bunch and you might be glad you dont have that rear night site, many prefer that configuration now. Also 10-8 makes a good rear site as well for this setup.
