Wu Silent Pistol

The WU Silent Pistol, officially the Windurger No.2 Silent Pistol, was a special tranquilizer pistol that replaced the Mk22 Hush Puppy as the standard sidearem for MSF and later Diamond Dogs. It is essentially a modified pistol that fires small-caliber tranquillizer rounds. There ware two models of the WU pistol, the 1975 model with built-in suppressor, and the 1984 model with detachable suppressor that would wear out. The overall design is meant to produce little gas or recoil, enabling its built-in suppressor to maintain its function indefinitely. To further limit noise, its rounds have a low muzzle velocity, resulting in a short effective range.

It appears that the WU Silent Pistol is specially-made by and for Big Boss's mercenary units.
