A system is for evacuating cartridges, applied to a firearm 1. The firearm includes a breech 14, a firing chamber 12 in which the projectile that will come out through a barrel 13 is fired. The evacuation system includes an evacuation tray 2, adapted to receive the cartridge following deflagration of an ammunition, and a movement mechanism 3, adapted to move the tray 2. The movement mechanism 3 turns the evacuation tray 2 about an axis “X”, parallel to the axis of the barrel 13 of the firearm 1, in a preset and appropriately cadenced way, passing from a first position, where the cartridge is received, to a second position, where the cartridge is expelled by the expulsion mechanism 5, and vice versa.
