Following the Dunblane massacre, the government passed the Firearms (Amendment) Act 1997 and the Firearms (Amendment) (No. 2) Act 1997, defining "short firearms" as Section 5 Prohibited Weapons, which effectively banned private possession of handguns almost completely in Great Britain. Exceptions to the ban include muzzle-loading guns, pistols of historic interest (such as pistols used in notable crimes, rare prototypes, unusual serial numbers, guns forming part of a collection), guns used for starting sporting events, signal pistols, pistols that are of particular aesthetic interest (such as engraved or jewelled guns) and shot pistols for pest control. Even the UK's Olympic shooters fell under this ban; shooters could only train in Northern Ireland (where the ban did not apply), or outside of the UK, be that in the Crown Dependencies (made up of the Channel Islands and Isle of Man), or in foreign nations (in Switzerland, in practice). Prior to the 2012 London Olympics, British Shooting negotiated an agreement with the Home Office to issue Section 5 Permits to a limited number of nominated elite athletes, allowing them to keep pistols and train on the UK Mainland at nominated "Section 5 Ranges". This agreement was renewed following the Olympics and Section 5 Permits remain on issue for eligible members of the GB Squad.
