what type of sights will fit an NP29 then? I've done some googling, but never come up with a concrete answer. do I absolutely have to get the slide milled or is there an aftermarket option?
The rear sight dovetail is a standard Colt 1911 dovetail. Any Colt 1911 sight will fit. I installed the LPA model on several.
The front sight dovetail is non-standard and narrow. It needs to be widened to suit the front sight you buy - like this:
Or, you can paint the existing chromed sight, or file the chrome off it and blue the face.
