Firearm for shooting projectiles by means of the synergic effect of a propulsive explosion produced by a principal cartridge (7) and of a second explosion, which takes place in a time immediately subsequent to the previous one, and which is produced by a supplementary blank cartridge (4) provided in a supplementary firing chamber (2) communicating with the barrel (1) of the firearm by means of connection holes (3). The second explosion is primed automatically by the action of combustion gases produced by the principal cartridge (7). |
