Q317: How can a visitor to the UK possess firearms or shotguns?
The holder of a visitor's firearm permit may, without holding a firearm certificate, have in his possession any firearm, and have in his possession, purchase or acquire any ammunition, to which section 1 of the Firearms Act 1968 applies.
The holder of a visitor's shotgun permit may, without holding a shotgun certificate, have shotguns in his possession and purchase or acquire shotguns. See Q318 for how to obtain a visitor's permit.
Please note that all calls to police involving firearms are treated as if it is a genuine firearm so be aware that if you do wave an imitation firearm around you could find yourself surrounded by firearms officers pointing real weapons at you.
