Day and Night. If it's a relative then I just reholster. If it's someone that I don't know then the chain lock is kept in place and I open the door with left hand, gun in right.
At night I get kind of rude (if it's someone I don't know). I shout through the door, "What do you want?" (I have an outside light that comes on when someone comes up so I can watch their actions).
"uh, dude, is XXXXXX here".
"Wrong house, go away".
Hey, it's my house and I don't have to be nice if I don't want to
