Walther PDP

The Walther PDP (Performance Duty Pistol) is a 9×19mm Parabellum semi-automatic pistol designed in 2021 by Walther Arms as a replacement for the Walther PPQ. The PDP has been designed to be more modular than previous Walther handguns, and has been described by Walther as their flagship handgun.

History
The first pre-production PDPs were distributed in 2020, and the pistol was released in February 2021. As the PDP was released, the PPQ ceased production.

Design
The PDP is a striker-fired, recoil-operated semi-automatic pistol chambered in 9×19mm Parabellum, with a longer grip and larger magazine capacity than the previous Walther design, the PPQ. The PDP is produced in full-size and compact grip frame variants. The grip uses a custom texture, which makes acquisition of the red dot easier, and improves handling of the pistol in adverse weather conditions.

The slide on the PDP is milled, allowing it to accept red dot sights without prior modification, and the slide contains serrations above the surface, making it easier to operate. The three-dot iron sight line features the same mounting method that is used on Glock pistols, meaning the PDP can accept aftermarket Glock iron sight lines.

The trigger is cross-compatible with the PPQ, but is lighter due to a shortened takeup. It has a trigger pull of approximately 25 N.

Reception
American Rifleman called the PDP an "excellent addition to the market that will allow Walther to compete strongly against the established leaders", praising its "best-in-class trigger, excellent controls and exceptional accuracy." The author said that it outperformed other striker-fired pistols he had used in the past, and went on to call the PDP his "current choice" for striker-fired pistols. Guns & Ammo described it as "the most modular and versatile pistol designed by Walther", also noting its accuracy and high quality trigger.

Guns.com called the PDP's ergonomics "revolutionary", and named it as one of the best guns of the year.

Variants
In 2022, Walther released a new competition-oriented variant of the PDP at that year's SHOT Show, the PDP SD Pro, which includes a threaded barrel, reinforced optic cut, flared magwell extension, and an improved trigger.

In late 2022, Walther released the PDP F-Series which features “reduced trigger reach, reduced grip circumference, and reduced force necessary to operate the slide and you truly have the perfect tool for those with smaller hands.”

In December 2023, Walther released the PDP Match and PDP Match Steel Frame.
