Abstract: A revolver-type firearm has a barrel-cylinder gap created between its barrel and a rotatable cartridge cylinder. The cartridge cylinder has a plurality of cartridge chambers each with corresponding counterbore retaining a translatable shuttle. When a cartridge is fired, the shuttle expands and translates forward toward the breech-end of the barrel and seals the barrel-cylinder gap to prevent the escape of gases, flames, and residue through the barrel-cylinder gap. When pressure drops as the cartridge projectile exits the barrel, the shuttle contracts. The barrel-cylinder gap opens upon rotation of the cartridge cylinder as the shuttle translates away from the breech-end of the barrel. The shuttle has a thin cylindrical body, a beveled front end, and a conical central bore and is manufactured from a hard elastic metal or metal alloy such as one comprising titanium.

Abstract: A revolver cylinder is rotated at least approximately at a speed that corresponds to the normal rate of fire of a weapon. When a predetermined loading step is reached, the trigger of the weapon is controlled such that fire can be opened essentially without delay. The weapon is fired without break immediately after (with) the loading process. At the same time, the weapon is transferred, thus only directly before firing, from a secure SAFE state to the CHARGED state, whereby the safety standards of the weapon are significantly improved. The time during which the weapon is in the state of operational and firing readiness and not in the SAFE state is minimized or entirely eliminated, which considerably increases the operating safety. Extending the time in the SAFE state allows the level of testing for the weapon (for example for the trigger) to be greater, which in turn results in greater reliability of the weapon.
