I Have a Police Positive Special 32-20 mfg. in 1924. It is in good shape, nice and tight....except for one little problem. The barrel (5 1/2?) is bulged and split right behind the front sight. I'm just wonderin' where I can find a barrel and whether or not it's worth the money to replace (gunsmith and all). Will any 32 barrel fit or does it absolutely have to be a 32WCF? It was a great shooter until the evil brother-in-law got a hold of it...
