Maybe it's a bit better than I thought if that goes for urban areas as well. Can you buy a pump shotgun? Can you keep the shotgun loaded? (In Canada they will charge you with improper storage - at least it used be that way). Do you know if you can you buy 00 shotshells and shotgun slugs and also can you buy ammo without a permit?
There is nothing to stop you buying a gun in an urban area. You must have a gun safe though and they may refuse you a permit if they think that there is high chance it might be stolen, so ironically, its more difficult to own a gun if you live in a high crime area. If you want to own a gun, especially a rifle, you’d better first secure your house before applying for a license, especially if you live in a rough area.
Pump shotguns require a firearms certificate, which has a higher standard than a shotgun certificate, and unlike a shotgun certificate, you have to justify why you should have it rather than the police justifying why you should not have it. certain types of shogun ammo, including slugs, also require a firearms certificate.
You need a relevant license to purchase ammo and you are not allowed to store the gun loaded.
Basically, you are not allowed to keep the gun loaded and ready beside your bed, so if a burglar robbed your house, you would have to grab some shells, make your way to the gun cabinet, unlock it, remove the shotgun, load it, and then hunt down the intruder. Thanks to a recent judges ruling, it is clear you can shoot burglars without fear of prosecution. It wasn’t very clear before.
