Sadly, I can’t advise you on that except to recommend you install a perimeter fence and a lock so no one can come ring your doorbell ever again.
For the last 10 years I haven’t lived where anyone could approach the front door. We also have large dogs (XTRA LARGE GREAT DANES) and a yappy little hound mutt to bark like nuts if someone even tries the gate.
Any area that is open to public to walk up to, is too easy a target. 1911 aside, that is a later layer of defense of the home in this day and age.
I like that idea. A lot.
