I did this to a Springfield that had bad melonite job and became rusty so I had to remove everything from sights to internals . Once I had taken out the original sights they did not stay in tight , I put a drop of red locktite on the slide and slid in the sight , stays perfectly and is very very tight now . . Didnt have to do anything to the dovetail other than add the locktite. You might try that , you wont be out anything and it wont damage anything. I have read that this is what some of the manufacturers do anyway .
