^^ this. Get a nice decent reliable inexpensive Shotty with 00 Buckshot and sleep well.
I look at this way, if I fire from the upstairs/cat-walk in our house, it's going down - no care.
If I fire from ground level and miss, the houses around me don't likely that I know of have bedrooms on the first floor. Now if I accidentally kill my neighbor in his living room rubbing one out on his couch with his laptop on his coffee table at 3am as I'm being robbed, I will deal with that later.
