Notes: This silenced pistol was not only one of the first truly silenced firearms, it was also for a long time the standard against which other silenced firearms were measured for silence. It was developed by the British SOE during World War 2 for use by assassins and resistance fighters. The Welrod is effectively a bolt-action weapon; when fired, the striking of the hammer is the only sound the Weirod makes. This sound, and any other sound, is muffled by the extremely effective silencer that in built into the weapon. The Welrod is cocked by turning the knob at the rear of the weapon, pulling it back, pushing it forward, and then turning the knob back again. The Welrods have been out of service for quite a while, though rumors of its use persisted into the early 1980s.
