While I would HIGHLY reccomend checking it out first hand with the ATF, I am inclined to believe that it might be alright to do. The reason I say this is to cite the Lemat revolvers as an example with it's 20 guage center pin/shotgun barrel. But liek I said, DO NOT take my word for it! Check it out with the ATF. Better to be safe than doing 10 years in club fed.
