It was more than just cosmetic. The wear of the finish was indicative of the fact that the frame wasn't machined right, so it was re-machined, and the frame/slide were re-fit.
They "repaired" it, and sent it back like the pictures above (page 3). I know SA is a sacred cow, but I wouldn't call that top not customer service when they return it like they did. Then again, I had a good example with SIG, whom many have complain about.
