Hey Boge, I've posted this here before, but I learned this trick from Colt.

Take a pointed center punch similar to this one...there are most certainly better ones...just an example:

Remove the sight. Grab a big, heavy hammer. Set the slide on a sound but rag-buffered surface (something like the flat rear "anvil" part of a large vice). Arrange the punch in the center of the dovetail, and then whack the crap out of it. And test and repeat until you've raised up enough metal from the divot to where you can securely drive the sight back in with a flat punch

Just saying, its always good practice to work on the part of lessor value. Beating on the slide like that instead of peening the sharp edges of the dovetail on the sight would not normally be expected.
