@BOLDYSPICY! You know what you need to do.
To be fair I don't see a good reason for a Civilian to own one, they are banned in the UK and in most of the EU because they found favor with people like Drug Dealers, Football Hooligans, and other criminal elements, and sadly there where a few deaths caused by people owning them and using them improperly.
Hell the Police are told under no circumstances are they to be allowed to be used above the neck if they do and the person survives they can get slapped with a attempted murder charge (I think there are one or two exceptions for this but they are very few an far between).
