Ahh...this topic once again. I speak for myself when saying this....a hand gun round is ineffective, period. Regardless of caliber, size, capacity. Think of it this way. In most cases, you're trying to punch a hole into a boney mass with a small piece of lead. Sure, we see death and other unfortunate incidents caused by hand guns all the time. But to trust your life, your family's life, to a tiny projectile is foolish. There is no fool-proof way to protect ourselves. We protect ourselves with hand guns HOPING that if the need arises, it will save us from the BG. This is exactly where endless amounts of training and familiarizing ourselves with our weapons comes into play. Do I feel safe when carrying, yes. Is my confidence and personal safety a gaurantee that 3 BG's won't come into my house, kill me and my wife, and take me for what I'm worth? Nope. Is my military background, my job title, and my weapons training a gaurantee for my very existence? Nope. But constant training does help....regardless of what I carry.
To comment on 'the only one stop shot is one to the forehead':
Not only is the skull the most armored part of your body, it's round...thus making the chance for deflection much greater. Plus, it's the hardest part of the body to hit!
