As of the time I learned this, some years ago when I talked to the guy who owned Trail Guns Armoury and instigated the Kodiaks, the Pedersoli was not regulated in the sense that a British best would be. That's what kept the cost down. The barrels were assembled in a jig so that in the finished reult the barrels would shoot fairly close together but did not have true regulation.

It was indicated to me that there was a bit of trade secret involved as at the time CVA sold a muzzle loading double that was jig assembled and laser aligned but did not do nearly as well as the Pedersoli for the barrels shooting close together.
