To answer the original question:
1) You do not shoot it if it is not in proper, safe working order.
2) You do not shoot it if it is (as a collector friend has) something like a mint Adams double-action only (no hammer spur) revolver in the silk-lined original case with all the accessories and a finish that is perfect. Looks just about unfired - it's been sitting in that case for 150 years! A revolver that even I, with my practical it's-there-to-be-used attitude only handled with cotton gloves. That sort of revolver is indeed too good to be used. So if it were given to me in some fantasy world, I would sell it to get a couple or three competition guns and still have enough money left over to feed them for the rest of my life!
