Pete,

Removal of offal in the bore is perfectly legitimate. It did not come from the factory. Removal of .001 of metal is quite different. That would be changing the condition of the pistol.
Honing of the bore is the same as reboring or reaming. It removes metal.
The bore should be cleaned but not restored.
Some like cleaned grips and others like the patina of age (oil & dirt). That is another question.
