Abstract
The invention relates to a cylinder firearm whose cylinder (100) includes a plurality of chambers (108). The cylinder (100) includes a channel (101) associated with each of its chambers (108) and opening out into said chamber ahead of any cartridge contained therein, with the other end of each channel receiving a piston (111), which piston presses against the frame of the gun when fired, thereby causing the cylinder to move forwardly by reaction and thus suppressing the operating clearance provided between the cylinder and the barrel and thus providing good sealing at the front of each chamber when fired. The invention is particularly applicable to revolvers.
