I never answer the door without my 1911 in my hidden hand pointed at the door.

Never point a gun a anything you don’t intendo to shoot.
Same here, but it's a 38 Special.
There's a great scene in the movie "Leon, The Professional" when a bad guy, looking for the little girl, comes up to Leon's apartment and presses his ear to the door.
Leon is tracking him through the peephole and had his Beretta aimed at the guy. The cool part is when the bad guy moves his head around, listening, Leon tracks him, moving his pistol so that it is always pointed at his head.
