From the gun’s excellent dodecahedron-style texturing to the SuperTerrain slide serrations, to the its 18-round capacity magazines, the Walther Performance Duty Pistol (PDP) is dressed to impress. Over the last decade, we’ve been witness to Walther’s modern focus on ergonomics, and this latest market entry is nothing short of exemplary.

The Walther Arms Full-Size PDP 4.5” is a user-friendly, ergonomic pistol made for the modern era, chambered for 9 mm Luger and enhanced by engineering to accommodate pistol optics. Even though the striker-fired PDP can be traced back to the company’s PPQ and Q Series guns, it is most certainly a different gun that is designed to help the shooter optimize his/her performance on the range.

With the PDP Full-Size 4.5” model, you get a duty-size pistol that measures 5.7" tall with an overall length of 8". Empty weight of this model PDP tips the scale at 22.3 ozs., add in an empty 18-round magazine and the weight jumps up nearly three ozs.

All of our tests with the Performance Duty Pistol concluded that this recoil-operated semi-automatic is a feature-rich design and provides a lot of features for the money. The addition of optic plates to customize the pistol to your style of red-dot optic is a worthwhile feature in a market that is increasingly more saturated with optic-ready options.
