PDP Features video "Red Dot Ergonomics" built-in providing the shooter an easier experience in locating your dot. The RDS Ergonomics on 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 RDS Ergonomics have been engineered to allow shooters to locate the red-dot instantly when presenting, achieved by engineered pinky pressure and offhand support. The PDP grip angle is designed for a natural aiming position which complimented and coupled with the innovative RDS Ergonomics, allow lightning-fast acquisition of the red-dot. When you are READY to make the switch to using an RDS the PDP is engineered to get you there faster and easier. The bump-out at the bottom of the grip forces the shooter to point the nose of the gun down making the red dot easier to find. Link to PDP: https://waltherarms.com/pdp/
