Product evolution

The Walther PPQ is not a true de novo pistol design. It shares its engineering principles and main features with the Walther P99QA variant of the P99 pistol that was introduced in 1996. Many modifications compared to the Walther P99QA like the re-designed grip, trigger guard, slide with forward (big) serrations and extended magazine release levers made their combined appearance in 2008 in the Walther P99 RAD, a P99 variant made in Poland and marketed as a military sidearm proposition.

Due to product evolution the PPQ maintains compatibility with both P99 sights and P99 second-generation magazines and other accessories.

The main innovation of the PPQ over the P99QA and P99 RAD is its 'Quick Defense' trigger.

 pistol. The PPQ 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 preset striker 'Quick Defense' trigger of the PPQ is a departure of previous Walther pistols and has been developed for the PPQ. When the trigger is pulled the trigger bar engages a disconnect lever, which props up a sear hook, which releases the fully pre-loaded striker assembly, firing the pistol. Pulling the trigger does not partially load the striker spring as with the Glock

 and many other striker fired pistol designs. The PPQ trigger pull is entirely due to the trigger and disconnector springs. The PPQ has a trigger travel of approximately 9 mm (0.354330708661417 in) with a relatively short trigger reset of 2.5 mm (0.0984251968503937 in) and a trigger pull of approximately 25 N (5.6 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. It should however be noted that the striker of the PPQ variant does not protrude from the back of the slide, as the firearm is in a constant cocked state.

Due to its trigger characteristics the PPQ pistol is marketed by Walther in Germany as a special forces pistol and not as a police duty pistol. For obtaining a German Police

Ergonomics and fully ambidextrous controls 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 trigger guard itself is squared off at the front and textured. 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. The hollow cross pin that secures the lower end of the backstrap was designed to function as a loophole for attachment of a lanyard. Under the dust cover the grip frame has an integrated mounting MIL-STD-1913 (Picatinny) rail for attaching accessories, such as a tactical light

The Tenifer finish is between 0.4 mm (0.015748031496063 in) and 0.5 mm (0.0196850393700787 in) in thickness, and is characterized by extreme resistance to wear and corrosion; it penetrates the metal, and treated parts have similar properties even below the surface to a certain depth.

 in the form of a the extractor on the right side of the slide that gets recessed in the slide when a cartridge is present in the chamber. When the extractor is recessed a red coloured indicator at the end of the extractor also becomes visible.

Feeding

The PPQ feeds from staggered-column or double stack magazines of varying capacity. Walther also offers staggered-column magazines with a +2 baseplate that add 2 rounds to the magazine capacity at the expense of extending the grip and the pistol height by approximately 18 mm (0.708661417322835 in). For jurisdictions which restrict magazine capacity to 10 rounds, Walther offers single stack 10-round magazines. 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 an orange coloured plastic follower.
The standard staggered-column PPQ magazines weigh 80 g (2.8 oz)
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 levers are located on the left sand right sides of the frame directly beneath the slide and can be manipulated by the thumb of the shooting hand. When a cartridge is present in the chamber the pistol can be fired without the need of having a magazine inserted in the weapon.

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

 by exchanging the front sight. For this Walther offers front sight elements in four differing heights. The standard sights have 3 high-contrast dots which serve as contrast enhancements and have been painted with afterglow paint to aid target acquisition under unfavourable lighting conditions.
The sight radius is for 156 mm (6.1 in) for the PPQ 9×19mm Parabellum models and 158 mm (6.2 in) for the PPQ .40 S&W models.

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.

For the recording of weapon specific data, a passive RFID transponder may be integrated into the backstrap of the pistol. The stored data can be read via an external unit.

Variants

The PPQ TACTICAL NAVY is a variant which has a firing mechanism that has been modified for operations in and near water. A non-standard hole in the striker channel ensures sufficient water displacement if the weapon becomes completely flooded with water. Hydraulic resistance is offset by means of a stronger striker spring. In addition, special guides reduce the hydraulic resistance when the striker moves forward.
These pistols are delivered with a standard staggered-column magazine and a second magazine with a +2 baseplate that add 2 rounds to the magazine capacity

The PPQ TACTICAL NAVY SD is the same pistol as the PPQ TACTICAL NAVY with the addition of a 118 mm (4.6 in) long special barrel with a threaded muzzle for mounting a suppressor.
