Here's a gun safety idea that would have stopped the Sandy Hook killer dead in his tracks

74. In defense of my own life, absolutely

A firearm is always to be considered the last line of defense.

First step is always to call 911 if possible!

Second step is to lock yourself in a room inside the house and make sure the 911 dispatcher knows exactly where in the house you are. Not just a room name, but where in the house that room is located.

Once you are in the room, never peek out the window. The arriving officers do not know you from the intruder and things can get bad real quick, and the arriving officers may be plain clothes and you mistake them for another intruder.

I somewhat agree that a shotgun is the best firearm to use, but not for the reason you are thinking. Nothing is more unmistakeable than the sound of a pump shotgun being chambered.

If and only if the intuder breaks into the room you are located do you think about the use of deadly force.

Now, back to why I only somewhat agree to the use of a shotgun. At the close range of an indoor defense setting, the pattern of projectiles out of a shotgun would never have a chance to open. Basically you would be sending out one large mass. A shotgun can be difficult to maneuver if you are trapped in a hallway or other small room. So in some cases a handgun would be a better choice of weapon.
