Whatever you decide to protect your family and home with do not become overzealous in the use of your firearms on your property.
Last week a mid-20's male knocked on my door at 2330 hours. I always go to the door armed at this hour, unless I am expecting someone.
I saw him through the front door, but opted to go around through my garage, and I told my wife to lock me out. I then instructed her that if she heard anything to call the sheriff.
I then hit the garage door opener, and the guy walked around and entered my garage within 20 feet of me. He then reached for his back pocket, and I drew on him. He almost wet and soiled his pants!
He brought out an iPhone, and I asked him why he was here. I withdrew my pistol, and he said that he was wondering if he could park his broken-down truck on my property for the evening.
You can see how this could have turned into a really bad situation! I instructed him to never enter anyone's garage, whom he didn't know, and walk toward them without being asked to enter at ANY time of the day or night. Then I told him never, under any circumstance to reach for his back pocket before being greeted!
I guess the moral of this story is to not draw your weapon until you are absolutely positive that the person is hostile. However, in my situation, how was I to know?
Someone with less training and a hot head might have fired before seeing what he was bringing from around his back.
