Reforms, ban, call it what you like, criminals or anyone intent to do harm will get a gun regardless, if not a gun then something else knife,hammer,acid car/truck, whatever, they will still do harm. The way to tackle it is a real deterrent , such as a meaningful sentence , not just community orders, if caught with a knife, gun, acid etc without having a legitimate cause to carry it, and real life sentences for murder/attempted murder/ acid attacks. Unfortunately ,to many of today's younger generation, these sentences will be seen as a goal, not gaol.
