It’s been a while since I looked into but I think it’s not a rule at a national level, but the canton police have significant flexibility on whether they approve applications for semi-automatic rifles and handguns. So one place might have requirements that another might not.

But for all manually operated firearms it’s pretty cruise-y.

Edit: the more I look into there’s lot of different permits with overlap, shall issue or must issue etc. Swiss bureaucracy. Etc. But I guess my point is like if a persons want a pump action shotgun or a bolt action rifle they’d get it very quickly, and be able to keep it at home with ammo, for more complicated guns it might be harder.
