1. Without prejudice to Article 2(2), Member States shall take all appropriate measures to prohibit the acquisition and possession of the firearms, the essential components and the ammunition classified in category A. They shall ensure that those firearms, essential components and ammunition unlawfully held in contravention of that prohibition are impounded.
2. For the protection of the security of critical infrastructure, commercial shipping, high-value convoys and sensitive premises, as well as for national defence, educational, cultural, research and historical purposes, and without prejudice to paragraph 1, the national competent authorities may grant, in individual cases, exceptionally and in a duly reasoned manner, authorisations for firearms, essential components and ammunition classified in category A where this is not contrary to public security or public order.
3. Member States may choose to grant to collectors, in individual special cases, exceptionally and in a duly reasoned manner, authorisations to acquire and possess firearms, essential components and ammunition classified in category A, subject to strict conditions on security, including the demonstration to the national competent authorities that measures are in place to address any risks to public security or public order and that the firearms, essential components or ammunition concerned are stored with a level of security proportionate to the risks associated with unauthorised access to such items.
Member States shall ensure that collectors authorised under the first subparagraph of this paragraph are identifiable within the data-filing systems referred to in Article 4. Such authorised collectors shall be obliged to maintain a register of all firearms in their possession classified in category A, which shall be accessible to the national competent authorities. Member States shall establish an appropriate monitoring system with respect to such authorised collectors, taking all relevant factors into account.
4. Member States may authorise dealers or brokers, in their respective professional capacities, to acquire, manufacture, deactivate, repair, supply, transfer and possess firearms, essential components and ammunition classified in category A, subject to strict conditions regarding security.
5. Member States may authorise museums to acquire and possess firearms, essential components and ammunition classified in category A, subject to strict conditions regarding security.
6. Member States may authorise target shooters to acquire and possess semi-automatic firearms classified in point 6 or 7 of category A, subject to the following conditions:
(a) a satisfactory assessment of relevant information arising from the application of Article 5(2);
(b) provision of proof that the target shooter concerned is actively practising for or participating in shooting competitions recognised by an officially recognised shooting sports organisation of the Member State concerned or by an internationally established and officially recognised shooting sport federation; and
(c) provision of a certificate from an officially recognised shooting sports organisation confirming that:
the target shooter is a member of a shooting club and has been regularly practising target shooting in it for at least 12 months; and
the firearm in question fulfils the specifications required for a shooting discipline recognised by an internationally established and officially recognised shooting sport federation.
As regards firearms classified in point 6 of category A, Member States applying a military system based on general conscription and having in place over the last 50 years a system of transfer of military firearms to persons leaving the army after fulfilling their military duties may grant to those persons, in their capacity as a target shooter, an authorisation to keep one firearm used during the mandatory military period. The relevant public authority shall transform those firearms into semi-automatic firearms and shall periodically check that the persons using such firearms do not represent a risk to public security. The provisions set out in points (a), (b) and (c) of the first subparagraph shall apply.
7. Authorisations granted under this Article shall be reviewed periodically at intervals not exceeding 5 years.]
