I didn't know I had such pitting until I removed the grips on my Luger.
I would like to be able to fix the pistol up but I am not sure how to deal with deep pitting or how to tell how much is too much.
I took some photos, but they are not real clear. You can see the rust for sure.

Any ideas on how best to stop the rest and then re-blue or ?
Thanks,
