If you install them on a really tight dovetail, a small amount might need to be taken off the bottom of the sight with a file. Then, if you want to put them on a different gun with a loose dovetail, you will appreciate having a way to tighten them.

I'd suggest you remove the screw and measure its length. Assuming the hole goes all the way through and isn't designed to just spread a split dovetail, you can measure the thickness of the sight (depth of the hole) before grinding anything off of the set screw. Also, you want to make sure there isn't something in the hole that is blocking the screw.
