I've unholstered 3 times but place my hand upon my firearm (without drawing) every time I go to answer the door. 2 of the unholsterings (is that even a word?
) were at my home.
Unholstered:
1) My mom (lives with us and has the downstairs bedroom) heard a noise outside her bedroom about 1am. She woke me & I went out with gun drawn. Turned out to be my BIL (he lived with us at the time) bringing up the wheelie bins as he just returned from working late. Scared him to death (almost).
2) Sitting around watching TV one evening, the front door handle started rattling and it was obvious someone was eying to get in. I was out of my chair, gun drawn & leveled at the front door, when it opened and my BIL (no longer lived with us but still had a key) walked in. He freaked, I reholstered, all was good.
Needless to say, my BIL now calls to let us know he's coming over and texts when he's at the door, just so I don't draw on him again.
3) Medical City Dallas parking garage. I was parked out of the way, no other vehicles around me, nothing in the area I was parked. 3 young looking guys were approaching where I was, staring at me the whole time. I hollered, asking what they needed, no answer. Placed my hand on my gun and asked what they needed again. No answer. Drew but kept it low by my side. One saw it, said something to the others, and they changed direction. I went back in and reported it to security, who called the police, who looked around, didn't find anything, and left.
As for just placing my hand on my gun, every time I go to answer my door I do so. That way, should it be something bad, I'm faster at the draw. If everything is kosher, I just drop my hand and the person at the door is none the wiser.
Interesting side-story to that though. One day, about 10am or so, there was a knock at my door. I went to answer, asked who it was, and it was the local police. I still had my hand on my gun when I opened it, saw it really was the cops, and dropped my hand. The officer wanted to let me know that someone had egged my van out front. So we went, looked at it, filed a report, and talked for a few. Before she left, she asked me if I carried. I told her yes, and she said that was smart how I answered the door. She's the only one who has ever noticed that I keep my hand on my gun when answering the door.
