Just finished watching a show that promoted a 9mm carbine for home defense. The show has also talked about tactics for "clearing" your home for burglars. Having a gun that comes through a door 2' before you to me is almost as ridiculous as trying to search your house by yourself. Someone breaks in your home you put yourself between your family and whatever threat is there and call 911. One, any Police Officer on this thread will tell you one person can't do this safely. Two, you don't leave your family so satisfy your ego you are a real man and can do this. You are there to stop anyone getting to people who are depending on you to protect them. Sorry about the rant. Just get tired of shows that promote things that can get people hurt.
