The Walther PPK CO2 BB gun is a replica of the classic Walther PPK made famous by movie spy 007. This compact pistol features all metal construction (except the hand grip panels), blow back, and fires in single action. The single action uses some of the CO2 from the blow back to cock the gun for the next round to be fired. When all BBs are fired, the slide locks back to let you know your out.
The Walther PPK is available in the following versions. PPK Black, PPK with Silver Slide, PPK Black with laser sight, PPK Black with pink grips (why?), and the now discontinued PPK Classic with ivory grips with silencer and extra black grips. I’ve seen the classic still being sold online.
The Walther CP99 Compact by Umarex is a faithful reproduction of the Walther P99 Compact. This sturdy little pistol sports a metal blow back slide and fires in single action. The single action uses some of the CO2 from the blow back to cock the gun for the next round to be fired.
The Walther CP99 Compact is constructed of a high quality polymer plastic, and features combat style grips. The blow back on this pistol is quite powerful and can be quite surprising to the uninitiated.
