Abstract: Provided is a revolver with a two chambers cylinder, of the type having a low profile and with no protruding parts from the frame. The revolver includes a frame which has a grip at its rear portion, a trigger at its lower portion and a barrel at its front portion. The frame further includes a central opening that defines the cylinder housing. The cylinder has an oblong shape and has two chambers, radially opposite with respect to the rotation axis of the cylinder. The cylinder rotation before firing is obtained by means of the trigger actuation, which causes an upward movement of the cylinder impeller and the consequent rotation of the gear, due to interaction between the pinion and the teeth of the cylinder impeller. The transfer of the rotational movement of the gear to the cylinder is made from a ratchet, which is partially arranged within said cylinder.
