Whatever you choose, I must quote the great nimrod Elmer Fudd " be vewy,vewy quiet" about it's presence. There is no need to advertise to either burglars ( firearms are a high theft item) or nieghbors who may be hostile to the idea or like to chit chat. Input of our prosecutor and retired CHIP should be interesting. Overpenetration in urban environs is a serious concern. I like a humble .38 converted to double action only. I load the old 200 grain super police. It is fast, accurate and relatively safe around young hands that try to pull that heavier triggerpull.
