What I meant to say is in America when we want to add second set of barrels to make gun more versatile we simply buy another shotgun. If one picks the right gun to begin with it isn't so bad. For example, while choke tube system can be a pain in the ass a piece of thin threaded pice is a lot less expensive than entire new barrel or set of barrels.
