Bad Bob is correct,,But!! it is an easy fix,,Put the colt grips on and just file the frame down flush with the grip panels,,Then reblue the bare steel . A few tips before doing this,,Deepen the slot in the screw head before filing the bottom of grip strap because you will also be filing down the head of the screw at the same time,,Also you will need to drill a hole for the grip pin ,,just put one grip on and mark the trigger guard strap in proper place,, If after putting pin in and if you notice any play in the grip you can fix that with a drop of bedding compound in the grip pin hole,,I have replaced the one piece grips on several of my Uberti revolvers with the colt black eagle grips this way.
