The Police Pistol Slim (PPS) packs Walther innovation into an unbelievable 1.04"-wide profile. Available in 9mm or .40S&W, the PPS has several notable features aimed at better fit and safe performance in its narrow dimensions. From your choice of perfect-fitting backstrap (small or large) to the patented QuickSafe™ innovation, the PPS sets the bar high for competing designs. Ambidextrous magazine release is easily located by right-and left-handed shooters. Loaded chamber and cocking indicators show when a round is chambered and the pistol is ready to fire. Three safety systems ensure peace of mind. A trigger safety and internal striker safety prevent accidental discharge. Simply remove the QuickSafe™ backstrap when storing the pistol to prevent the PPS from firing. The 9mm caliber comes with a seven-round magazine. A six-round magazine is included with the .40S&W model.
