House broken into yesterday.. home defense help needed

As far as self defense guns to have in your home there as many opinions as guns but here is a little something to consider. What are the interior and exterior walls of your home made of? If they are like most sheet rock interior and sheet rock/sheeting and siding exterior a 9mm full metal jacket bullet will penetrate up to 11 walls, you don't know where that bullet is going to stop. OO buck is only a little better but again those little balls are going to go through a number of walls and the people between them. For the safety of those in other rooms and outside your home one of the safest options is an AR-15 with hollow point bullets. These will be absolutely lethal to anyone in the direct path but these super soft bullets will self destruct on contact with a solid object like a sheet rock wall, tested by the FBI. A short barreled model with a collapsible stock is quick handling and gives a great sense of security. As a bonus they are great fun to take out and shoot for pleasure as well which you make you a lot more proficient and confidant.
