The Walther PDP Compact 4" Set delivers the full performance of the PDP CO₂ platform while adding the advantage of the integrated Umarex RDS 8 Red Dot Sight. Designed for precision, realism, and fast target acquisition, this model combines the familiar duty-pistol ergonomics of the PDP series with a reliable blowback system and strong structural build quality.

The metal Optics Ready (OR) slide ensures compatibility with major red dot footprints such as Vortex, Leupold, C-More, and Trijicon when using optional adapter plates. The included RDS 8 sight mounts directly, providing enhanced visibility and rapid alignment for training or recreational shooting.

Powered by a 12 g CO₂ capsule, the pistol reaches velocities of 120 m/s (394 fps) while staying under the <3.0 J energy limit. The 18-round steel BB magazine feeds smoothly, and a shot capacity of approximately 72 rounds per CO₂ cartridge allows extended shooting sessions without interruption. The crisp and powerful blowback effect simulates realistic cycling with every shot.

Additional features include an Automatic Trigger Safety, Sliding Manual Safety, and a trigger blade lock to reduce the risk of accidental discharge. The Picatinny rail under the dust cover supports tactical attachments such as flashlights or lasers, expanding the pistol’s functionality. The piercing tool for the CO₂ capsule is conveniently integrated into the back of the grip for quick cartridge changes.

At 183 mm in length and 684 g, the PDP Compact Set maintains the weight and handling characteristics expected from a modern duty-style air pistol. With its optic-ready slide, metal construction, blowback action and included RDS 8 red dot, the PDP Compact 4" Set is a versatile and highly effective CO₂ BB pistol for realistic practice and everyday recreational use.
