Patches on the right side look like Bubba tried to beat out the slide stop without aligning it with the takedown notch. Would take bead blasting or flat sanding the whole side of the gun to clean up, and I don't know if that would get the divots out of the bottom corner of the slide.
I can't see anything wrong with the left side, but if you are going to work on the right side, you would probably have to do the left; those textures are not real easy to match.
