PRODUCT DESCRIPTION

Machine translated

Walther PDP Compact 4" Blowback is a modern air pistol that faithfully follows the live service pistol Walther PDP. It offers a realistic shooting feel thanks to the blowback system, high-quality workmanship, and comfortable ergonomics for sport shooting as well as manipulation training. The pistol fires steel BBs in 4.5 mm caliber and is ideal for dynamic recreational shooting at short distances.

Durable construction and realistic blowback slide

The construction combines a metal slide with a robust polymer frame, providing a good balance between durability and weight. The 96 mm barrel ensures compact dimensions and pleasant balance during shooting. Thanks to the blowback system, the slide moves realistically to the rear when firing, simulating recoil and giving the shooting an authentic feel similar to a live firearm. This makes it an excellent tool for training grip, aiming, and trigger control.

CO2 power – easy handling and stable performance

The pistol is powered by a standard 12 g CO2 cartridge, which is inserted into the grip. This system allows for quick cartridge replacement without complex tools and ensures stable pressure for most of the shots. CO2 power offers comfortable shooting without the need to cock a spring – just load the magazine, insert the cartridge, and you can start shooting.

Magazine for steel BBs

Walther PDP Compact 4 uses a magazine for 4.5 mm steel BBs. The magazine integrates space for both the ammunition and the CO2 cartridge, so replacement is quick and intuitive. Simple loading and handling of the magazine enables fast dynamic shooting, reloading, and training of tactical habits. The magazine capacity is 18 BBs.

Sights and mounting systems

Fixed iron sights provide a clear sight picture and are designed for quick target acquisition. There is also a module on the slide for adapters for mounting a red dot sight if needed. The frame features an integrated accessory rail (Picatinny/Weaver type), onto which you can mount a tactical flashlight or laser sight. Thanks to this rail, you can easily adapt the pistol configuration to your shooting style, improving both comfort and aiming efficiency.

Trigger mechanism and safety

The modern trigger mechanism is designed for smooth operation and good controllability. The trigger has a comfortable shape for a secure finger contact and allows precise control of the shot, which is essential for both training and recreational shooting. Safe handling is supported by an integrated safety system that allows you to secure the pistol against unintentional discharge.

The trigger is a bit sluggish, otherwise a good fun device.
