I have had the pleasure of shooting several different full autos. My favorite was one called a scorpion, if I remember right. It was like a mini mp5, that was chambered in 32 acp. That little sucker sure shot fast, and didn't hardly recoil at all. Just put the sight on the target, squeeze the trigger, and bzzzzzt, 30 holes in the target. The guy who owned it told me a lot of foreign body guards carry them because they are small, and very effective.
