A looong time ago, my first cap&ball was a 1849 baby dragoon by Navy Arms.
I believe the inside parts were made of zinc, they were that soft.
I have no idea who made that piece of junk, but the revolver was new ( 1970 vintage )as years went by, I found out, the only repro revolvers to buy were the Uberti brand. Their fit and finish, also the working parts were properly hardened.
Through years of use the Uberti revolvers are still good and tight.
I have never seen a brass framed cap & ball that was worth any more than $ 10, even that was too much.
I suppose a brass framed gun would be good enough for a one time use.....whatever that would be. Probably to shoot myself in the foot, for being so stupid, for buying it in the first place.
