John Brown will sort you out at Browns lock stock and barrel ,Hillsborough,and he wont rip you off ,you will get looked after,
if your only just filling your forms out ,you will have a good few weeks/months wait for them to be approved,sheffields feo is spot on as well.
as far as shotguns are concerned theres loads to choose from ,but like said on earlier post ,get to shop and look at a few.
