So ive been reading alot lately about spanish best sidelocks and live pigeon guns are mentioned often. They are often described as having a wider thicker action. Im curious as to how the barrels are joined and fitted? Is there just more space as in more metal between the barrels or are the barrels just thicker? If so are they regulated in the same manner as double rifles which have a far greater spread between the barrels at the muzzle? Ive never held one to inspect one myself but have lately been very interested in them. Or are they simply a more ornate magnum wildfowling gun ?
