The Ministry of Defence keeps an updated register on transfers of weapons for military use, as well as on weapons possessed and stocked by armed and security forces.
The Ministry of the Interior is responsible for the register of small arms for civil use, which contains information on arms produced, imported, exported and transferred. Each register includes information on the following elements: manufacturer, number, model, calibre and elements of the transaction (date, entities involved, licence).
Other facts, such as the theft, loss and apprehension of arms, are subject to register.
