A grenade shot fire extinguisher to put out fires out of 50m for convenience, to minimize weight and to reduce users dangerous elements at the time of putting out fires.
And minimized its weight factor by installing its magazine up to place the center of gravity in the waist.
To maximize an effect of putting out fires, I put compressive fire-extinguishing powder into the existing bullets for delay explosion.
So, the fire-extinguishing scope of fire-extinguishing bullets can be maximized by making the bullets exploded in the sky at the time of shooting the bullets with a fire-extinguishing gun.
