Walther PP Super 9x18 Ultra caliber. The Walther PP Super is an all-steel, blowback operated, double action pistol. Unlike its predecessor, the Walther PP, the PP Super featured an external slide stop lever, and a manual decocker on the left side of the slide, which, when pushed down, locked the firing pin and released the hammer, and then automatically returned to the 'fire' position. There was no manual safety, but the PP Super has a firing pin safety, and was intended to be carried with the loaded chamber and hammer down, ready to be fired in double action mode. The magazine catch is located on the side of the grip, next to triggerguard. Layaway available. Credit cards accepted at a 3.5% fee.
