Yes sir, that looks correct. Suggest removal of sufficient material to make it even, or slightly longer (past) than the end of the extractor rod. The .010" was a suggestion about the limit to it's being out past the end of the rod.

I would just take material off the end of the pin by stoning or filing until your opening and closing feels "normal". The end does not need to be polished. Check the end of the extractor rod and front locking bolt for evidence of burrs too, while you're at it. Check them with a magnifier.
