I watched an interview with the Dali Lama once. This American documentarian and devout Buddhist asked the holy man if he thought killing someone is acceptable. The Lama answered, "Life is the most precious thing. Your life is no less precious than another. So if someone is trying to take your life or cause you serious bodily harm, you not only have the right to protect your life by taking his, but you have an obligation to do so." The interviewer was so shocked at the answer that he paused, eyes wide, and in a stuttering voice asked the question again. The Lama, being a very wise man restated the same point of view.
Let's put statistics aside for a moment. Because numbers are often B.S. from both sides of the issue manipulated and at times outright fabricated to prove a point. The reality is that if I were in a situation where someone was intending to do immediate bodily harm to me or a member of my family, I hope I will have something that will stop the person from performing that act. I realize that introducing a gun could actually increase my chances of being seriously injured or killed, or the same happening to whoever is nearby. But remember, I am already defending against an immediate threat. There is no time to decide, only react. In this situation, doing nothing means I will die. Doing something may also mean I die, but may help me live. I don't believe in pulling out a gun to scare someone off. If it happens to scare someone off and they stop the attack good, but that is not the reason for pulling a gun out. I pull a gun out to stop that person from continuing his or her action. The only way I will know that person will stop from advancing is to completely incapacitate him or her. There is no shooting in the leg. There are no warning shots. I have a couple of seconds to stop that person. That's it. It is two or three shots to the chest area. If I am lucky they will stop. If not, I shoot more. This is not the movies. People don't just stop when they are shot. Someone who is in a rage or so violent that they want to kill me, my wife, or my son, don't give a damn about a bullet hole. All I can hope for it that their blood pressure drops fast enough to force them to stop. I don't intend to kill them. I am not a killer by any stretch of the word. I am not even a violent person. But if they die because of my attempt to stop them, I can live with that. But I am sure it will haunt me for the rest of my life. (I am sure any decent cop who faced the same would feel the same way.)

I use them for recreational purposes only. If someone really wants to get serious about home defense, an effective perimeter and security system is way more effective. Can't go to the store and buy that for $600 though. I'm also not delusional enough to think if there were ever an "popular uprising" against a "tyrannical police/military force" that my handguns would be effective for more than 2-3 seconds against the kind of stuff they employ.
