The Walther PPS (Polizei-Pistole Schmal / Police Pistol Slim) is a semi-automatic pistol developed by the German company Carl Walther GmbH Sportwaffen of Ulm for concealed carry for civilians and plainclothes law enforcement personnel. It is available in either 9×19mm Parabellum or .40 S&W chamberings. It was first shown in 2007 at the IWA & OutdoorClassics and is a slim polymer framed weapon of similar size to the Walther PPK pistol. The PPS is however technically much more based on the Walther P99 pistol.
PPS pistols manufactured by Walther in Ulm, Germany are imported to the United States through an exclusive agreement with Smith and Wesson. The PPS pistols are also made under license in Poland by Fabryka Broni Radom.
