Just FYI that's actually different depending on local laws. I don't live in an open carry state so I very much don't have the right to carry a gun in public. Not unless I went through the rigorous process to get a carry permit.
I can't name even a single example where societies, even if it is only at a state level, generally allow citizens to carry a gun in public (without having to acquire some special permission that only very few people have access to)
If there is some other society that allows this then it's probably an Anglophone country.
The US has a gun-culture where collection of guns is done without any overt reason. In Urban areas, guns are basically never really owned, much less carried openly.
