The Welrod pistol used a manually operated rotating bolt. The
knurled knob at the back of the gun would be rotated and the
bolt pulled back to extract a fired case, and the pushed forward
and rotated to lock a new cartridge in the chamber. The magazine
was encased in a rubber sleeve, and formed the grip of the gun.
The trigger mechanism was simple, but did include a functional
grip safety. The Welrod was made in both 9x19mm and .32ACP
calibers – this one is a 9mm example. The two types can be
easily differentiated by the trigger guard – the 9mm model has
one and the .32 does not. The suppressor portion of the gun was
very much a disposable unit, which would only last about 15
shots before performance began to decline quickly. Expected
effective range of the gun was 8 yards at night, and 25 in
daylight. This was a gun designed for a very specific purpose,
and not intended to be used in general service. For example, the
muzzle was made a bit concave, explicitly to improve sound
reduction when pressed into a tar
