Guns are fairly common in Sweden, but strictly regulated. You need to pass a test to be allowed to own guns, sort of like you need a driver's license to drive a car, and you need to store them in an approved safe when not in use. Also, your gun license can be revoked for medical reasons.
https://en.wikipedia.org/wiki/Overview_ ... ion#SwedenGun ownership in Sweden is regulated by Vapenlagen 1996:67 (literally, The Weapon Law), modified by weapon decree Vapenförordningen 1996:70 and FAP 551-3 / RPSFS 2009:13. The police issue licenses to persons in good standing who have passed a hunting examination or belonged to an approved shooting club for six months. License-holders are usually 18 years or older, and may lend a weapon to a person at least 15 years of age for supervised use.
A license-holder may own up to six hunting rifles, ten handguns, or a mix of eight rifles and handguns. Firearms must be stored in an approved safe. A firearm registered for sport shooting may not be used for hunting. A concealed carry permit can be obtained under very special circumstances, such as a proven threat to life.
Firearm collectors must have a clearly stated demarcation of their interest in collecting (e.g.: pre-World War II British handguns). The police may demand security measures on keeping the collection. Collectors may request a time-limited permit to discharge their weapons. Firearms manufactured before 1890 and not using sealed cartridges are exempt from the weapon law
The problem in the USA is that the NRA opposes even rather benign common sense laws, such as digital registers regarding ownership of guns, mental health checks, waiting periods, what have you.
In both Britain and in Australia, it took just one school shooting to make authorities step up and impose stricter gun control, and neither country has suffered another school shooting. And imho those are perfectly fine countries, hardly gruesome dictatorships.
