Q329: Can I have an imitation firearm?
Yes, however it is an offence to possess an imitation firearm in a public place (unless the person can prove he / she has a reasonable excuse) or to manufacture, import or sell a realistic imitation firearm. There are some exceptions for weapons used in historical re-enactments, theatrical productions and film making.
An imitation firearm has been defined as 'anything, which has the appearance of a firearm' so could include toy guns. Many imitation weapons are very realistic and until the weapon has been seized it is difficult to ascertain whether it is genuine or not.
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.
