Anybody wishing to acquire firearms and exercise actual control over them requires a permit in accordance with Section 10 (1) of the Weapons Act.

This is issued in the form of a weapons possession card:

Green weapons possession card
This is the most common form of gun ownership card and must usually be applied for before purchasing a gun. In principle, any type of firearm can be registered on it. The target group is: Hunting license holders, heirs of firearms, sport shooters, firearms license holders.

Yellow gun ownership card
Under certain conditions, it allows sports shooters to purchase single-shot long guns, repeating long guns with rifled barrels, single-shot single-shot short guns and multi-shot short guns with primer ignition (percussion weapons).

Red gun possession card
It enables gun and ammunition collectors who are scientifically or technically active or who want to build up a culturally and historically significant collection to acquire firearms, whereby the permit is usually limited to a specific area of firearms.
What all cards have in common is that they permit the possession but not the carrying of weapons.
The term "carrying" refers to the ready-to-hand carrying of the weapon outside the home, business premises or a pacified property. Anyone wishing to carry a weapon generally requires a firearms license.
The so-called "small firearms license" is generally required to carry (type-approved) alarm, irritant and signal weapons.
