[2] The revolver was developed by TsKIB SOO from 1991 to 1992 and was meant for sale to the Ministry of Internal Affairs and to law enforcement.
In 1992 it was adopted by Ministry of the Interior of the Russian Federation as service weapon under designation RSA (Revolver Stechkina-Avraamova).
There is a safety on the left-hand side of the grip[3] that locks the cylinder and hammer to prevent it from accidental discharge.
Since it fires rimless cartridges, the six-shot revolver is cut for "moon clips", sheet-metal holders that grasp the rounds by the base to allow them to be extracted easily.
It can also be used without the "moon clips", but the spent cases would not be extractable unless pushed out from the front of the cylinder with a rod-like object, like a pen or pencil.
