Paul M, pistols & revolvers that shoot bullets are illegal, but Air pistols and pistols that use black powder, are not, though 2 of the pistols that I have are now illegal to sell, but I got a Firearms Certificate so that I could keep the 2 that I have.
I have joined the rifle club to have access to safe, Police & M O D monitored target ranges.
Homer, your best bet would be to buy a copy of air gunner, and see if there are any local gunshops near where you live, or google search for gunshops in your area, as the staff would be best able to advise you on what is available, what would suit your needs best, the legal implications, and any local clubs that you could join.

essential reading for anyone thinking of getting an air weapon
and finally, weapons are not the problem it is the idiotic few who misuse them that are the problem, the Police went through extremely indepth checks before I was granted my Certificate.
Thanks.
