The Russians also have the OTs-38 "Vorchun"/"Croaker", a revolver designed by Igor Stechkin (the same guy who designed the APS machine pistol); this uses 7.62 SP-4 internally-silenced ammunition with a sliding cup inside the case to stop gasses from escaping to the outside atmosphere, and will penetrate a helmet or CRISAT target from 15 metres. These fire from the bottom chamber in the cylinder, and usually have a laser sight built into a tube where the barrel would normally be.
Interesting. That looks like the wheelgun equivalent of the PSS, which I believe uses the same cartridge. It's a semi auto though. Very compact and quiet.

The PSS was developed to give Soviet special forces and secret police an almost completely silent option for covert operations such as reconnaissance and assassinations. The weapon uses a unique cartridge with an internal piston to achieve this end. Otherwise, it is a fairly simple double action pistol. Few details are known about the pistol's performance, as only a few have entered western hands.

The PSS uses a specially developed 7.62x42mm necked round SP-4 (СП-4).[1] The cartridge contains an internal piston and a propelling charge, with the stem of the piston against the base of the bullet. On firing, the piston delivers enough impulse to project the bullet from the barrel to an effective range of 25 meters. The piston then seals the cartridge neck, preventing noise, smoke, or blast from escaping the barrel.[2]
