As far as I know, the gun-possession laws are fairly strict in Norway, but considerably less strict than in Old Europe and the European Union (neither to which Norway belongs).
In Finland, a member of the European Union, for example, about a year ago, Brussels ruled that Finns are not allowed to use firearms to protect themselves against wolves. Now one sees one of the reasons Norway is not a member of Old Europe.
There are several authentic Norwegians actually in Norway on the Norway ping list; perhaps one of them can answer this question, but remember the time difference.
I believe some knives are illegal to carry too. Its a difference between the knives used for outdoor and the stabbing knives. As for guns and rifle possession Norway ranks high.
The police are unarmed and most have a permit to carry guns in troublesome situations.
Not long ago a son shot down a car thief when he was driving their car heading against his father. Most of my friend were happy. Finally justice. WHATS MINE IS MINE!!!! If you wanted to take a chance on robbing me you may pay the ultimate penalty.
I am happy to inform you that we have quite relaxed laws in Norway concerning gun ownership. Some people says we may rival you in USA in guns per person, and that is just fine with me.
It dates back to the bad, old days, when the law stated that all adult men should have their own weapons. Those who did not have any, for some reason or another, was punished.
If you are 18 or older, you may own as many shotguns and hunting rifles as you like. (But not AK-47, M-16 and other automatic rifles, nor sub machine guns.)
If you are 21 or older and active member of a pistol club, you may purchase handguns, usually only one in each caliber. I own two and are thinking of buying more.
You are allowed to keep your guns in your home.
Please excuse my bad English.
