Please could you supply a list of all registered civilian weapons in the territory of the United Kingdom between January 2015 and October 2018.
We said
Thank you for your request.
Unfortunately we do not hold information regarding registered civilian weapons.
The Home Office publish data on Firearm certificates in England and Wales.
They would be in a better position to answer your query, and can be contacted by email at CrimeandPoliceStats@homeoffice.gsi.gov.uk
