I wonder if anyone here could clear up some confusion for me please, I've tried the search function but cannot really find the answer I'm looking for.
I have 3 shot capacity Benelli M2 on my shotgun certificate. I possess a FAC. I have capacity on my FAC to acquire a section 1 shotgun. I would like, if possible, to obtain a longer magazine tube and use it, within the conditions of my FAC, but have the option to use the shorter 2 shot mag for clays, game and wildfowl. Is this feasible, or does the law not allow for one weapon to be categorised in different ways? It would save me buying an identical gun just because it has a longer magazine tube, and cut down the number of weapons I own.
