RSh-12

The RSh-12 (Револьвер Штурмовой калибра 12,7) is a Russian-made revolver chambered in 12.7×55mm STs-130.

It fires from the bottom chamber of the cylinder (like the Chiappa Rhino and Mateba Autorevolver) rather than the more common top chamber, and is chambered for the same ammunition as the ShAK-12 battle rifle and VKS rifle.
