I have a couple of questions, I have a friend I hardly trust a word that comes out of his mouth. I would like to see what is true and what is made up. 1. .38 specials are very inaccurate firearms. 2. If you shot an intruder or somebody trying to harm you in the head with a .22, that person could still take 15 steps. ( doubt this is true, because when the .22 round enters the skull it doesn't exit, so it bounces off the back of the skull and does major damage to the brain.) 3. .40's are better than .9 mm because the round travels faster making it more accurate in a self defense situation.
