Metal parts that rub together or make contact with other metal parts will get visibly marked, scratched, or burnished. Even very hard finishes, like the black nitride and gold TiN finishes we use will wear and that will be visible. Stainless parts will also get scratched, burnished, and show where they rub and touch other parts. This is normal and is not a defect. We have seen that when we replace a barrel in one of our pistols, the new barrel seems to show the same sort of wear pattern as the barrel we removed.
