462 mm (18.2 in) with folded stock[1] 679 mm (26.7 in) with unfolded stock[1] The RSh-12 (Russian: Револьвер Штурмовой калибра 12,7, romanized: Revolver Shturmovoy kalibra 12.7, lit.

'Assault revolver calibre 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.

Originally introduced in 2020, by late 2021 these pistols are still in final stages of development, and there’s no firm information on their future availability and pricing.
