The Swiss model: Every able-bodied male citizen from late adolescence to the age of retirement is by law a member of the Swiss army, and MUST keep a firearm in working order and ample ammunition in the home.
A similar statute exists in Israel, a country that has been besieged since its founding, where the citizenry is essentially the militia, and every citizen receives training in the care and feeding of firearms. Again, possession of firearms in the home is strongly encouraged, with the police and members on active duty with the IDF authorized to carry at all times.
This is what made a noble different from a commoner ~ a nobleman had a "right to keep and bear arms". A town, in fact, might be granted part of the right ~ so many swords, so many cannon, warhorses, etc.
This right also carries with it the news that someone so honored can go to the public courts and bring suit against someone else and ask that the armed might of the government be brought into a dispute!
This was a real problem for commoners and Jews throughout Europe for centuries ~ unless they could settle a dispute privately, they had no access to the courts.
On the other hand, the courts had access to them!
I think one of the Justices limited his construction of the 'bear arms' part of the expression to just carrying around a weapon. Actually, he really missed the boat on that one ~ and with him a judge, and before that a lawyer, it tells me of the sad state of teaching history in our nation's universities!
