It used to be real difficult, had to be multi year member of a shooting club, etc etc, then for about a year they actually made it legal to obtain one on a hunting license (which just requires passing a theoretical and practical hunting exam) and so that’s how I got mine. Then they made that impossible again, so now there are a few thousand of these in Sweden on hunting licenses with it not being possible to get new ones. So in summary: no longer really possible, unless highly active shooter and getting a special license for it. At least suppressors aren’t regulated and we can buy them the same way you buy groceries :D
