I mean I guess it’s a better system then just being able to walk into a random store and just buy a gun. In my country we have a pretty strict gun control you need have not committed any crimes and be able to get a document from the government saying so, you’ll also need the following;

1. be part of a gun club, which itself has a cool down period of several months and they can refuse you for whatever reason they see fit
2. have a minimum amount of shooting days per year
3. have to participate in the yearly contest for one of the different disciplines possible at the club
4. have to be a continuous member of previously mentioned club at least one year before you can even apply for your first licence
5. your first licence can only be in a single .22 weapon, this weapons will be registered to you as a person and your place of residence
6. your gun and ammo needs to be in separate safe’s, also the gun may not be stored in a loaded state
7. after you have the weapon you will be checked at random and you need to be able to show the weapon at the visiting police officer immediately, or if you cannot show it at the local police station within a few days after the visit. if they visit they will check if your safe('s) are properly mounted to wall/floor
8. have to extend your licence yearly
9. if you fail the checks or violate any laws you will lose your license and you will need to either store your weapon(s) at a registered location or sell them, evidence of both will need to be shared with the police. you can apply for a new licence after one year of probation
10. the maximum amount of weapons you can have registered at any time is 5

Firearms are either considered a part of sport (hence the clubs) of for hunting which has their own subset of rules. You can never have any full automatic firearms, those are considered for military use only.
