PURPOSE: A small firearm of a dual-firing type is provided to enhance the operational stability by ensuring a firing position even while a barrel moves. CONSTITUTION: A small firearm of a dual-firing type comprises a barrel carrier and a breechblock carrier. The barrel carrier and the breechblock carrier are respectively constrained to a barrel carrier fixer and a trigger firing lock. The breechblock carrier is released from the trigger firing lock and then moves forth and thus the barrel carrier fixer is released. While the breechblock carrier and the barrel carrier move forth, the breechblock carrier fires ammunition. After firing, the breechblock carrier is moved back in the barrel carrier by a breechblock carrier fixer and while the breechblock and barrel carriers move back, the barrel carrier is released from the barrel carrier fixer and is fixed to the trigger firing lock and the barrel carrier is located to have an initial firing ready state.
