I wouldnt shoot them simply because if something were to break in them and had to be replaced, I think the value would decrease. I could be way off, but I would want to keep them as absolutely original as possible.
I have a mild interest in guns. Actually, I think the clinical term is "obsession," but that makes me sound like some kind of gun-nut. Which is fair, since I am.
