Weapons or their essential parts are rendered permanently unusable if their firing capability or function cannot be restored with commonly used tools.

However, if

• the chamber has not been permanently altered in such a way that neither ammunition nor propelling charges can be loaded,
• the breech has not been rendered permanently inoperable,
• the trigger mechanism in grips or other essential weapon parts for handguns has not been rendered permanently inoperable,
• in the case of handguns, the barrel does not have a full length, starting at the chamber,
  • a continuous longitudinal slot at least 4 mm wide up to the muzzle or
  • at intervals of 3 cm, but at least 3 caliber-sized holes or
  • other equivalent barrel modifications
    has,
• in the case of long guns, the barrel does not have at least 6 caliber-sized holes or other equivalent barrel modifications in the third facing the chamber and is permanently closed in front of these in the direction of the muzzle with a caliber-sized hardened steel pin,

then the same regulations continue to apply to these weapons as to functional weapons requiring a license.

You must have the weapons deactivated by a gunsmith/gun manufacturer. They will then issue you with a deactivation certificate as proof. You must keep the deactivation certificate together with the deactivated weapons or take it with you when transporting such weapons. If you lose the deactivation certificate, you must report this immediately to the relevant firearms authority.

If you have reported the deactivation and presented the deactivation certificate, the competent weapons authority will remove this weapon from your permit to possess and acquire weapons (WBK) and, if applicable, from your European firearms pass.

You can use the NWR identification numbers (NWR-ID) to complete the notification more quickly:

• Your Personal NWR ID (P or F NWR ID) for your personal details
• the permit NWR ID for the firearms permit (E-NWR ID)
• the weapon or weapon part NWR ID (W or T NWR ID).

You can obtain the NWR IDs on request from the relevant weapons authority.
