Ooooo...magazine fed, gas operated, semi-automatic, hand-held, .45 caliber, CANON! Not the fastest round, not known for accuracy beyond 50 mtrs, but that tumbling round will stop just about anyone with one round. It's hard to "wound" someone. You graze their arm or leg, it'll take it off. Dang! Good choice! Watch the recoil. You got to hang on. Don't squeeze it, but keep a good grip. You might get a scar in the top of your hand between the thumb & 1st finger from the action, but hey.
