Legal position by country

Every country has its own rules. For each, this shows how its firearms law classifies the item — with the wording, the legal reference and when it was checked. What applies in a given case depends on the country, the permits held and the gun.

prohibited: Possession is prohibited; at most an individual exemption from a central authority remains.
only with a permit or exemption: Allowed with a firearms licence, for certain purposes (such as hunting or sport) or with an official exemption — the wording says which.
depends on the device: For lights and lasers the consequence depends on the device (light or laser, laser class) and partly on the purpose — the wording says which.
not covered by firearms law: The country’s firearms act does not mention the item (for magazines: below the limit). Hunting, state or provincial law may still regulate it.
not surveyed: There is no checked statement for this country. That is not a clearance.
