Unfortunatl;ey flare pistols are section five. For those outside UK, Class 1 firearms, ie rifled barrel target rifles etc, ned a Police firarm certificate, isuued by local force. Section 5, prohibited weapons require a licnce granted by the Secratary of State. The classification covers all sorts of things including pepper spray. My vet has a blow gun used to dart anthitiose animals. This counts as section 5 because the drugs used are 'Noxious Substances'.
