A cartridge/carrier locking device is used for an automatic gun loading arrangement of a type for removing a cartridge from a magazine onto a carrier by releasing it from a locked state for firing and for pushing it up into a barrel chamber by an upward sway of the carrier which takes place in response to the forward stroke of a breech block. A latch plate which is provided with a first claw part at its forward end for locking the cartridge and a second claw part at its rear end for locking the carrier, is pivotally attached to an inner wall of a receiver containing the automatic gun loading arrangement. The first and second claw parts serve, respectively, to lock the cartridge and the carrier as the claw parts alternately protrude into the inside of the receiver in a swaying fashion. A spring is arranged to push the second claw part of the latch plate to the inside of the receiver. A locking part is also arranged at the rear end of the latch plate and engages with the breech block, the carrier and the cartridge to restrict the swaying motion of the second claw part into the inside of the receiver so that the engagement is released allowing the second claw part to act and to release the first claw part from its action only when a retracting stroke of the breech block comes to exceed to preset value after the gun is fired.
