As far as just being able to posess guns, I believe Sweeden (one of those S-countries) allows one full auto rifle per household (after they do their time in the military, of course).
Could be either Switzerland or Sweden. Its quite easy to get an AK4 here, as long as you have done military service. No need to keep it locked up, though I believe you must store it, or a vital part of it, in a safe manner...oh, and you don't get any ammo for it anymore (And its sooooo hard to get hold of .308 Winchester
)
Scandanavia is relatively friendly, and Europe is generally friendlier than the states when it cocmes to suppressors.
Generally speaking, Norway and Finland are better of than Sweden and Denmark, although us swedes are a bit better of than the danes, I believe they have a couple of restrictions on handgun calibers etc.)
Suppressors are OTC in Finland, AFAIK
.
New BP-guns requires a license here (and soon one won't be able to store the blackpowder at home
). One authority has decided its to much of a fire hazard...IOW, soon you won't be able to store more than two kilograms (appr. 4.5 lbs) of smokeless powder, so ya gotta keep track of how much gun powder your ammo contains - yes, its not "all the ammo you can fit into your locker, and two extra kilograms of gunpowder", its two kilograms in total
