Walther PDP Full Size 9mm Semi-automatic Pistol The all-new PDP combines a century of Walther know-how with modern design principles to create a Pistol built around maximizing the effectiveness of a red dot optic. All the hallmarks of Walther's unparalleled excellence are here-first-class ergonomics, amazing trigger, exceptional usability-but they've all been tweaked to make integrating and utilizing a red dot faster and easier than ever. The PDP features an incredibly deep optics cut-out that allows your red dot optic to ride lower in the slide while simultaneously allowing you to use the factory iron sights as a back-up option. The PDP doesn't come with a mounting plate out of the box, but as soon as you know which red dot you want, you simply contact Walther to get the corresponding optic mounting plate absolutely FREE of charge. (That means you aren't getting charged for optics plates you'll never use.) The ergonomics of the Walther PDP are designed around making the switch to the popular red-dot sight system easier for the new RDS shooter and faster for the RDS veterans. The bottom of the grip has been swept forward so that when you grasp the grip frame, your pinky pulls the muzzle upwards-allowing you to get onto the red dot sight picture faster. The PDP grip angle is designed for a natural aiming position which, complimented and coupled with the innovative RDS Ergonomics, allows for lightning-fast acquisition of the red-dot. The grip itself features the new PDT (Performance Duty Texture), providing an aggressive surface to maintain proper grip performance without aggravating your hand or rubbing on clothing. Whether it's torrential rainfall, extreme heat, humidity, or ice, the Performance Duty Texture keeps the pistol firmly planted in your hand. The slide also features innovative new SuperTerrain serrations. These serrations are actually raised above the surface of the slide, offering a more positive fee
