> Just a side note, because you’re from Norway, that may be surprising to some. The US is #1 with 1.01 guns per capita, and Norway is #9 with .31 guns per capita.
Being from #10 on that list, the type, quality and "outings" of guns matters a lot. In France, "owned guns" are either sport or hunting weapons, seeing one outside of hunting season basically does not happen and they're regulated:
* single-shot (per barrel) smooth bore long guns must be registered (for hunting or sports), buying requires showing an ID and either a hunting or a sports license (from an accredited gun club)
* air guns beyond 20j and various types of long runs replace the registering by a declaration (a more complex procedure)
* various more powerful and smaller weapons (including handguns) have to be authorised before they can be bought, for sports or defence (mostly professional). Amongst other concerns the would-be owner must have a clean criminal record, show a clean bill of health (physical & psych) under 1 month old and demonstrate ownership of a safe
* automatic, high-capacity (30 for long guns and 20 for handguns) and very-high caliber (>= 20mm) is forbidden
Guns must be disabled or under lock when not heading to, coming back from, or performing the activity they're used for.
I expect Norway, Finland, Canada or Germany are very similar: though specifics probably vary, weapons ownership is most likely regulated and generally restricted to hunting and sports (the licensed, olympics-able "Shooting Sports" kind, not the "I went at the range to play with a minigun" kind).
