Imitation firearms would also have to include many airguns, blank firers etc, so some sought of license possibly, that would involve millions of guns, a ban, possibly, but they would have to pay compensation, that would be billions. Who would run the license system, the police ? They are struggling in many forces to do renewals and grants for FAC’s and SGC’s, some people waiting a year for renewals.
The government did a ban/ or put it on licence with air cartridge guns, that backfired badly 60,000- 80,000 went underground according to government figures.
If Labour becomes the government next year than I expect more aggro for legal gun ownership, but when it comes to airsoft, airgun replicas your looking at huge volumes of guns & people.
