Markus A380 provides a detailed guide for disassembling and reassembling the fire control group of a VFC Walther PDP airsoft pistol. The process begins with the removal of the slide from the frame by pulling down on two side buttons. To extract the hammer assembly, a small screw is loosened, and the unit is lifted out while the presenter identifies specific internal springs and plastic components that must be handled carefully to avoid loss.

The teardown of the mechanism involves pushing out two pins to release the hammer, cocking lever, and various tension springs. He explains the orientation of each part, noting how the hammer spring and small latches fit into the casing. This stage highlights the internal differences between this model and similar airsoft platforms, emphasizing the need for tools like tweezers to manage the smaller components.

Reassembly requires placing the internal levers and springs back into their designated spots before driving the pins through the housing. Once the fire control group is rebuilt, it is lowered back into the pistol frame and secured with the original screw. The video concludes by reattaching the slide and performing a function test to ensure the trigger and hammer mechanisms operate correctly.
