Yeah, that'd cost you prob the price of 2 or more 219's to do? My father collects them. There's a 220 that is basically the same gun...and a stevens model, and variations on the models......may swap barrels? You wanna be careful on bbl swaps on them due to machining tolerances and equipment not necessarily being what modern day stuff is. There is also a diff between shotgun and rifle firing pins. There are guys that have "made" bbls by doing this and that, but its not factory-approved work, i'm sure. A net search will bring all kindsa ideas. The rifles bbls came factory in 30-30, 22 hornet, 25-20 & 32-20 as best i can tell. Shottys in 12, 16, 20 and 410.
