 pistol. The PPS has a glassfiber-reinforced polymer frame and steel slide assembly. It can be broken down into its main parts or field stripped with a take down catch without the help of tools.

Features

The internal pre-loaded internal striker is a variant of the partially cocked striker system of the Walther P99 Quick Action model. When the trigger is pulled, the already partially cocked striker is fully cocked and released, firing the pistol. An indicator on the back of the slide shows if the striker is partially cocked. The 'QuickSafe' trigger variant main difference with the Walther P99 Quick Action trigger is that removing the PPS pistol's backstrap will disable the gun for safe storage by decocking and blocking the striker until the backstrap is reinstalled.
The PPS has a trigger travel of approximately 6 mm (0.236220472440945 in) and a trigger pull of approximately 27 N (6.1 lbf). Unlike many other trigger systems preset internal strikers have a let-off point and trigger pull that remains unchanged from the first shot to the last and requires no decocker.

Ergonomics were a key focus in the design of the firearm, and as a result, three interchangeable grip backstraps are included (small, medium and large) to accommodate various hand shapes and sizes; this feature permits most shooters a comfortable and efficient grip on the firearm

 grip frame contains 4 steel guide rails for the slide: two at the rear of the frame, and the remaining pair above the front of the trigger guard. The polymer grip has a non-slip surface on the sides and both the front and rear straps and a slightly funneled magazine well to aid magazine insertion. Under the dust cover the grip frame has an integrated mounting MIL-STD-1913 (Picatinny) rail for attaching accessories, such as a tactical light

PPS pistols are delivered in a polymer pistol case containing; the pistol, 3 backstraps of different sizes, 2 magazine (small and medium), magazine loader, instruction manual, warranty papers, factory test target showing 5 shots fired at 15 m (16.4 yd) distance and an envelope with the case of the proof round fired during the proof test

 in the form of a witness opening at the top of the slide/ejection port. By looking into this opening the user can see if a cartridge is present in the chamber.

Feeding

The PPS feeds from single stack magazines of varying capacity. The various magazine capacities are achieved by small, medium (+1) or large (+2) magazine floorplates. The small magazine is flush with grip bottom. The extended +1 and +2 floorplates integrate with the gripframe adding finger rest space for better grip.
The magazines are made of steel for Walther by the Italian subcontractor MEC-GAR and have an anti friction coating for easy loading and anti-corrosion and witness holes to view how many rounds are in the magazine. A steel spring drives a plastic follower. The standard PPS magazines weigh 43 g (1.5 oz) (6/5 rounds of 9x19mm Parabellum/.40 S&W), 59 g (2.1 oz) }} (7/6 rounds of 9x19mm Parabellum/.40 S&W) and 67 g (2.4 oz) }} (8/7 rounds of 9x19mm Parabellum/.40 S&W).
After the last cartridge has been fired, the magazine follower exerts upward pressure on the slide stop causing it to engage the slide stop notch thereby holding it in the "open" position.

The slide stop release lever is located on the left side of the frame directly beneath the slide and can be manipulated by the thumb of the shooting hand for right handed shooters. When a cartridge is present in the chamber the pistol can be fired without the need of having a magazine inserted in the weapon. Walther does however offer a magazine disconnect as an optional safety on some PPS pistols that will prevent discharging the pistol without a magazine present in the pistol.

Empty magazines are released by depressing ambidextrous magazine release levers incorporated into the trigger guard

Overpressure ammunition

According to Walther “Plus-P” (+P) overpressure ammunition

 may affect the wear characteristics of the PPQ pistol or exceed the margin of safety. Use of “Plus-P” ammunition may according to Walther result in the need for more frequent service.
Walther recommends against the use of “Plus-P-Plus” (+P+) overpressure ammunition in Walther firearms. This marking on the ammunition designates that it exceeds established industry standards, but the designation does not represent defined pressure limits and therefore such ammunition may vary significantly as to the pressures generated.

Slide stop modification

Walther modified the slide stop lever and an accompanying spring on the PPS pistols to improve reliability. Early PPS pistols can be modified but need an enlargement of a hole in the pistol gripframe before the new style slide stop and spring can be installed. For this the pistol has to be sent in to the Walther customer service.
