Editing Firearm (section)

===United Kingdom===
In the UK, a firearm does not have to use a combustible propellant, as explained by [https://www.cps.gov.uk/legal-guidance/firearms Crown Prosecution Service Guidance Firearms] The Firearms Act 1968 Section 57(1B), uses the definition of a firearm as a "lethal barrelled weapon" as a "barrelled weapon of any description from which a shot, bullet or other missile, with kinetic energy of more than one joule as measured at the muzzle of the weapon, can be discharged". As such, low-energy air rifles and pistols also fall under UK firearm legislation, although the licensing requirements of low-energy weapons are more relaxed.
