The awarding-winning Walther "PDP" ("Performance Duty Pistol") is one of the newest additions to the handgun market by the storied German concern of Walther Arms. At its core, the gun is a conventional semi-automatic (striker-fired, recoil-operated) solution chambered in the ubiquitous 9x19mm Parabellum pistol cartridge. The PDP series overtook the PPQ (detailed elsewhere on MilitaryFactory.com) of 2011 once formally introduced in February of 2021.

Like other modern semi-automatic pistols, the PDP is offered in full-length and compact forms to better suit a demanding market - particularly the law enforcement and civilian firearms market found in the United States.

The handgun has a familiar design form with an angular, ergonomic pistol grip handled, curved trigger unit in a squared-off loop/ring, and a moving slide set over the frame of the gun. The milled slide has fore and aft serrations for improved gripping of the assembly and the ejection port is set to its right. A short section of Picatinny rail is featured under the muzzle for the mounting of aimers and tactical flashlights if desired. The take-down handle is above the trigger while the magazine release is within reach of the operating thumb. Take-down results in the pistol being broken up into five major parts for cleaning and maintenance. Construction is mainly of steel and polymer.

Weight is 1.68lb with an empty magazine inserted. Sighting is through a three dot iron sight arrangement with one component set at the rear of the frame and the other over the muzzle. After-market Glock-type sights are also supported.

Internally, the gun utilizes the short-recoil principle through a locked breech approach. Feeding is by way of a 15- or 18-round detachable box magazine inserted into the grip handle in the usual way. The compact version supports 15 rounds while the full-sized brethren is the full 18-round count.

Variants of the family line include both compact and full-length forms and, within these categories, sub-groups signifying varying barrel lengths (4", 4.5", and 5") and therefore varying ammo counts (the aforementioned 15- or 18-round magazines). The specialized PDP PRO SD is offered in 4" and 4.5" lengths and includes a threaded barrel for a suppressor as well as improvements to the trigger action. Both are 18-round models.©MilitaryFactory.com
