A friend and I are looking into the legality of manufacturing our own 597 barrels and they would finish out to about 12" to 13". Who would be interested in buying one and what would you pay? We both have 597's so the barrels would be well tested to ensure both that they worked and retained accuracy. They would be made from a heavy barrel blank and cut, crowned, and fitted to a 597. There would also be an option to have the end of the barrel threaded 1/2x28 for add on accessories such as a flash suppressor or compensator. Lets hear your input please.
