That'd be Switzerland. They are issued a Sig 500 series rifle (FA/burst/whatever) and a set amount of ammo on their completion of service (1-2 years, IIRC). Using said ammo outside of wartime is verboten. They are allowed to practice at ranges with the rifle, but (again, IIRC) they have to buy the ammo there and not take any home.
Yeah, it proves that having a lot of guns around doesn't increase crime, but drawing comparisons between Switzerland and the US is about as fallacious as drawing conclusions based on statistics between Japan and the UK, both of which have similar draconian anti-gun laws but wildly differing crime rates. The cultures are just completely different in all 4 countries.
And for my deleted-before-posting nitpicking (and the second paragraph above) let's just chalk it up to me playing devil's advocate as I agree completely with what you're saying but know how someone else would pick it apart.
