I had 2 Shield 2.0 9 mm to install sights on. I got the rear sight off of one and the front sight off the other with a Wheeler sight tool. The remaining sights would not move. I took then to the Gunsmith who used a large bench vise and a brass punch to remove the offending sights and install the new sights. The cost was $35 each.
The lesson learned is that sometimes you just have to give up and let the professional do it.
