This was originally an America Blank Gun so it used to top vent (Plugged Barrel) as per US regulations. I acquired a new frame with a front firing barrel making it a bit more realistic when shooting. It uses 8mm P.A.K. Blank Ammunition and holds 7 rounds. Even though it uses 8mm rather than 9mm blanks it's still very loud and field strips just like a real Walther PPK automatic hand gun.
