Those canny Ivans have come up with a rather interesting little pistol known as the PSS - NATO reporting name - VuL.
It is a blowback operated pistol, similar to the Makarov. The PSS fires the SP-4 7.62 x 41 ww mm silent round. (Apparently it makes the same sound as
an air rifle)
The pistol has no conventional suppressor, each cartridge containing a piston between the propelling charge and the cylindrically shaped bullet.
When fired, the propelling charge drives the internal piston and bullet forward where the piston is stopped by the cartridge's shoulder, where it
'obturates' the propelling the gases inside the cartridge case as the bullet is propelled forward.
Allegedly, the SP-4 round can penetrate 2 mm of verticle steel plate or standard battlefield helmets at a range of 25 m with enough energy to kill.
As you all know, there are 2 sounds when a weapon is fired, the loud 'bang' caused by the rapidly expanding gases and that of the round which
travells at supersonic speed. Those cany Russians have solved the latter problem by developing the 'closed-circuit' round (as described above), by
using less propellant and also by using the heavier 7.62 milly round.
Only drawback I can see, is the pathetic 6 round mag but, I think you'll all agree an otherwise neat little shooter.
