The name's Walther. Carl Walther. He's the man behind the most widely-recognized concealed carry guns due to its countless appearances in film. Walther takes credit with the Walther PPK DA/SA Semi-Auto Pistol as the firearm that created the class of concealed carry-sized pistols. Prior, there were full-sized handguns and micro pocket guns. The PPK created a business class where you get a combination of great concealment and real use capability due to the Walther's medium size. The PPK utilizes an internal slide lock. The slide-mounted safety/decocker can by used to apply the safety and drop the DA/SA trigger from single-action back to double-action. The classic black plastic grips resting on the steel frame pairs very well together. DA/SA Stainless steel construction Standard black plastic grips Internal slide lock Safety/decocker Hammer-fired
