40 S&W, 9×19mm Parabellum
The Walther PPS gun was officially unveiled on November 5, 2007 at the international weapons exhibition IWA. Like the P99 in its time, the PPS has become a sensation, as this newest German pistol is one of the thinnest in the world using a 9mm Parabellum cartridge. Today, the official distributor of Carl Walther Sportwaffen GmbH in the US is Smith & Wesson. But at the same time PPS is still a German pistol, as it is produced in Germany. Collaboration with the American Smith and Wesson and the use of the latest innovations in the design of small arms made Walter one of the leaders in the creation and production of ultra-compact 9mm self-loading pistols. The abbreviation PPS stands for Police Pistol Slim (or in German Polizei Pistole Schlank, which means "thin police pistol"). This is a typical designation for Carl Walther Sportwaffen GmbH, echoing the famous Walther PPK and as it continues its history and heritage.
Of course, PPS is not intended solely for the police. The main directions of using this weapon are self-defense with concealed carrying and carrying as a reserve weapon, both by ordinary citizens, and by police and special services officers. When designing the PPS, the designers were faced with the task of creating as much thin gun for the 9mm Parabellum cartridge as possible, and also that this model would not exceed the PPK 9mm caliber. Weapons for everyday wearing can not be too light, too thin or too powerful. In this case it was necessary to achieve the optimal ratio of dimensions, efficiency and convenience. To achieve this goal, designers had to seriously work on the layout of the nodes and mechanisms in the frame.
