Given our safe storage laws where the shotgun must be stored unloaded, trigger locked and ammunition stored separately, or together without a trigger lock in a safe. The choice of best or worst is pretty much immaterial.
Most of the gun media is from the states where it is legal to have a shotgun loaded. Loaded an eight round pump action shotgun would be a good home defense choice. Here complying with our safe storage laws less so.
Ammo can be in the same container as the gun as long as it's all locked up.
