I think Finland's gun laws are pretty much the same but I really don't know.
I remember that when I was a kid, my father kept his army pistol at home. Illegally, I suspect (it's too late to ask him now; he passed away a few years ago). And my older brother very nearly managed to shoot and kill my younger sister. The bullet went right past her and, as far as I know, is still in that wall somewhere. I don't know how my brother got hold of the weapon; I know it was locked away, and I didn't know exactly where, either.
