No there isn't. America has 120 guns per 100 people.
The closest runner-up country, the Falkand Islands, is almost exactly half of that - at 62 guns per 100 people [1]. There's a sharp decline from there.
That said, I've long shared the belief that despite the absurd number of guns in the USA, and how they literally outweigh the population; the average person ought to re-calibrate have more faith in humanity and respect for their access to firearms, because the stats for gun violence are not nearly as high as you'd think if they're that accessible.
Guns per capita isn't a good measure because some people own a lot of guns. Gun owning households is a better way to test how many kids potentially have access to a gun - https://en.wikipedia.org/wiki/Percent_of_households_with_gun... - America is still top at 42%, but the next country is at 37% and there are several above 20%.
