lol wow I know I'm gonna get shit for this, but here's the stance on the subject. A .22 is gonna stop someone. IF your in a situation where you have time to fire, you have time to place it properly. Unless your attacker is all jacked up on PCP a small caliber .22 is gonna cause enough pain that they'll stop, a round in the right shoulder (or left if their holding with their left) will cause them to drop their arm and weapon and it's about over. IF someone is out specifically to end your life, their not gonna ask you if you'd like to draw your weapon first, they have the element of surprise, and you'll be dead before you know there even was a situation. If the situation allows you to draw a weapon, most of the time that itself is enough to defuse the situation. If they have a gun pointed at you, and they firmly intend on killing you if you do not comply, you'll be dead before you can get your weapon out, theirs is drawn and aimed, yours is still in your waist band, holster, up your ass, where ever you keep it. Accuracy. If you can't hit a man sized object at 20 feet, you shouldn't have a gun. being able to hit a target at 500 yards is pointless in a SD situation. the extremely vast majority of SD conflicts are point blank, to 20 feet, after that it gets kinda hard to prove self defence. I've read on several CCW forums that the FBI did a study, and before you get a concled firearm out, a man with a knife can issue fatal cuts from as far away as 21 feet and a man with a drawn gun at any distance Okay I think I caused enough shit, I'm out.
