The OTs-38 Stechkin is a 5-shot, double-action revolver, in production and service since 2002, chambered in the silent 7.62×41mm SP-4 cartridge.
OTs-38 is innovative to a degree unusual even in special purpose weapons:
The cylinder pivots out to the right-hand side.
A manual safety catch that allows the pre-cocked hammer to be set on manual safety, enabling the revolver to be carried cocked. (The mechanism also prevents accidental discharge with the cylinder open or not fully closed, with the revolver dropped or struck.)
The barrel is mounted below the axis pin (the gun fires from the lowest cylinder chamber), so recoil is directed straight into the shooter's hand, rather than exerting a torque that raises the muzzle. This improves both accuracy and the maximum rate of fire.
The OTs-38 is fitted with an integral laser sight located above the cylinder axis (where a conventional revolver has its barrel) powered by three D-0.03D batteries*Ž
