Wonder what kind of rifles they get to keep home. Can you imagine getting to bring home an M16 when you join the national guard?
After they muster out they may keep what they were issued. If it were select fire (Full & Semi Auto) the full auto is deactivated after leaving the service. The Swiss put very little emphasis on full auto anyway, very much favouring AIMED fire.
I have been to Switzerland several times for work. Our factory there has an annual rifle shoot where everyone shows up with whatever they were issued. You will see everything back to old K-31s on the line.
In order to push through any real gun legislation there will have to be a national referendum. Most Swiss votes go that way. It means that very little gets done legislatively over there since you cannot simply sway some politicians, you must convince 51%+ of the nation. They need to remain vigilant on the issue of gun grabbers but are not nearly as threatened as we are.
Remember, this is the nation that flat out refused to join the EU. They also forbid building on farmland. The logic is that if Europe decides to go mad again they can close their borders, rip up the vinyards and plant potatos to feed the nation like in WWI and WWII. Te mountains are, as my Swiss counterpart told me, "Like Cheese." He meant there are tunnels and caves through out them and they are full of weapons, artillery, ammunition, tanks, you name it. They love trade as much or more than the next guy but still want to be able to tell the rest of the world to pound sand if needed.
As for this old gentleman's rifle, contact the family. They for the most part have a great sense of family history there. If you have their family member's gun it is not because the government took it from him, it is because he turned it in. Perhaps he was issued something newer, perhaps he jsut no longer wanted it, but it was not take from him.
Just on my last trip there in April I was waiting for my ride in the early morning air in Arburg. The town was just waking up and what comes walking across the old coverred bridge right into town and towards the gun shop, an older gentleman, possibly in his 80s, with his old issue K-31, still obviously maintained, slung over his shoulder. Nobody batted an eye.
