Only the Pug, Black Widow & MiniMaster have dovetailed sights and it appears that the rear dovetails all are different sizes. Other models have fixed metal sights that are part of or welded to the top rib, so it could be done if the top rib of your particular model is deep enough to file in the dovetail.
It would be beyond my metal working capability. I’d have to do as U.SFC_RET suggested above ... buy another NAA revolver with sights I wanted.
