Many years ago my late husband bought me a pistol after our home was broken into while he was away, and taught me how to use it. At that point I knew I could shoot someone. Did not know if I could prior to that and thought having it in the house would be more dangerous if I was ambivalent about using it. He died a few years ago and I was afraid about what to do about having it registered in my name since it was registered in his name and we were all receiving notices to reregister our weapons. This in a Democrat state. Turned out it was not a big deal. Had to do an on-line pistol use study and test, pay a small fee, and I was registered.
We had friends from church who had their back door kicked in one morning. The wife was sitting in the bed room with her husband who was dying in bed and she did not have her hearing aids in and did not hear him kick in the door. She turned around and he was standing there. Surprised both of them. He said how are you all doing and she said fine. He said, well I just wanted to check on ya'll and left. She sat there wondering who that guy was and could not remember who he was. She called our church secretary across the street and asked her if she had seen anyone. The secretary had not, but called the sheriff and they sent out a car to check it all out. They believe it was a guy who might have broken in other houses around our little community here. But, they never caught him. So, my wife is always armed. When I am in the living room, my pistol is right handy on the side table. I am never without it. Even when I am cutting grass around the back side of our lot here, my wife has her pistol handy and keeps all the doors secured so that no one could walk up in the front thru the garage doors when I leave open while out working. She just locks that door out of the garage into the house and keeps her shooting iron handy!!! Stay safe.
It is a shame that you had to register. In free states there is no gun registration. It's none of the government's business knowing who has or does not have a weapon.
