#NotCursed: I've seen shit like this in #Germany with double shotguns and double rifles with two two-round mags - one per barrel...
Sometimes even combined like a break-open combination gun...
After all, it's one budle of barrels thus only one gun on one's permit card.
And you better choose those wisely due to transfer limits and a maximum of two pistols [aka. anything with <60m overall and/or <30cm barrel lenght] and two long guns.
