"My Swiss friend in town told me as far as he knew Switzerland still people keep fully functional assault rifles at home but those who have them need to show up for three weeks of training each year and show up at a shooting range twice a year. (He left a few years ago so anyone actually living there now should feel free to correct this.)"

That's new law due to Schengen. If you had a gun before, you don't need to do this. Three weeks is probably the compulsory military service.
