Im finding Im a bit hesitant to wear the finish off stuff thats 50 or 60 years old or more and in excellent condition (younger me would be shocked), but a nice shiny new gun? Go use it. Besides, its stainless, it buffs out easily.
I think id find even more satisfaction putting a higher priced gun to good use and advantage than an ordinary one. There will be plenty of pristine ones around for the collectors.
