I do archery as a hobby and am thinking of taking up clay pigeon and practical shotgun shooting as a hobby. My ground floor flat which is in a bad area has been burgled/robbed three times before in two years, the thought of having a shotgun at home for home defence as an improvised weapon appeals. The last time we were robbed, three guys broke into our house at around 4am through a single glazed window round the back which the landlord was too stingy to upgrade to a double glazed uPVC window. My wife and I were promptly ushered at knifepoint into a disused airing cupboard which used to hold the hot water tank (since replaced with a combi boiler). The men proceeded to utterly ransack the house. The police arrived about 20 minutes after we freed ourselves and called them, which by then the robbers were long gone. They were not helpful and initially said they will call us in for a photo fit as the men were not wearing masks, and we saw them face to face. They never did call us in for a photo fit and after we tried calling them a few times to remind them and ask how their investigation was proceeding, we gave up. I am not very familiar with the laws with regard to using shotguns at home as a defensive weapon, what types are best and what shells are best. I don't want to ask the following questions at my range which I just joined so I will ask them anonymously here: The gun cabinet will fit in the walk-in closet in the master bedroom. Will the police be happy with it being situated here? Is it possible to legally own a semi automatic shotgun with several shells as a civilian? If I get a 3+1 round shotgun initially, how easily can it be upgraded (if legal) to a larger magazine? What shotguns do you guys recommend primarily for clay pigeon and practical shooting, but a secondary role as a home defence weapon? What are the best shells for home defence? I am looking for something that won't raise eyebrows if bought for sports/hunting but are equally effective against humans with heavy clothing. Is it possible to buy shotgun slugs rather than buckshot? Is keeping a loaded shotgun by the bed always inexcusable? Under what circumstances is it acceptable or not to use a shotgun for home defence? E.g. back shots.
