The US is the arms dealer of the world. It is American weapons going into Mexico and other Latin American countries that are causing problems there.
The lawful/licensed gun owners in Canada have to put up with potential bans because of the too ready availability of guns in the US that are smuggled over the border and make headlines.
I assume GP was talking about serious crew served weapons like artillery, MANPADS, and the like. You are correct that the US is already set in terms of small arms, with its civilian population owning more guns than all the militaries of the world combined[0].
That being said I think GP's prediction of a civil war triggered by inflation is hysteria.
