Okay, I have a SIG P226 that shoots high with a #8 front sight, so I ordered a #7 and a #5 from CDNN for $2.95 each rather than the $24.95 from the SIG website. (Lucky me!)
Now the question comes, what is the best tool to tap out the old sight and put in the new one? I have the usual brass punch set and hammer, but the dovetail on the sight is rather thin, and it's going to take a pretty small diameter punch to match up to that thin width. It looks to me like the flat base of a gun screwdriver would be a far better match to the base of the sight to drive it out.
So what is the best way to do this??
