I just inherited a shotgun from my father, which was a surprise since I didn't know he owned it until after his death. It's a Mossberg 500C and the guy who transferred it from Texas to Washington state for me said it hadn't been used in a long time. I assume it's pre-1968 (no serial number), and looks to be in very good condition. Would it be worth taking it to a gunsmith for inspection (I don't know anything about shotguns) before I try firing it? Any advice would be welcome.
