I immediately thought IRL-like, double barrel flamer.
Spraying massive amounts of flaming gasoline or napalm in an arc, so high drop, because liquid is heavy, but if you were good and aimed up could have some good range anyway.
this is, evidently, fairly respectable, and from a handheld model! Imagine the pressures this could be launched at...
In fact, maybe combine (somehow, through SUPERSCIENCE), a water jet cutter with a flamethrower...?
Western-Dragon themed barrels. Heads don't open, the nozzle sticks out of the head kind of like a lizard and it's tongue.
