Walther Umarex PDP Compact 4″ (Umarex – VFC – UM3T-PDP-BK01)
Optic-ready Umarex/VFC Walther PDP Compact 4″ — lightweight aluminium slide, guide-hop adjustable hop-up, 22-round gas magazine and realistic gas-blowback performance.
Description
The Umarex / VFC Walther PDP Compact 4″ (UM3T-PDP-BK01) gives you flagship PDP ergonomics in a compact, airsoft-friendly package. A die-cast/aluminium slide over an engineered polymer frame keeps weight down while delivering authentic slide mass and smooth blowback. The optics-ready slide accepts common micro-red dots (adapter plate compatibility), the pistol uses a high-capacity 22-round drop-out magazine and an adjustable guide-hop / “shoot-up” hop-up system lets you tune point-of-impact for your preferred BB weight. Clean lines, ergonomic backstraps and an under-rail for lights/lasers make this an excellent compact sidearm for CQB, training or a premium backup pistol.
