Morphology
The meaning 'a gun that fires gas' is directly and compositionally derivable from combining 'gas' and 'gun' — the noun–noun compound straightforwardly denotes a gun associated with gas. This follows common compounding patterns and is conceptually transparent across languages, so a B1 learner who knows both words would readily infer the intended meaning.
Etymology
The compound noun gas gun comes from the simple picture of a gun that fires gas. Imagine a launcher that shoots a cloud to make people or animals leave; that's why the term means a weapon used to release gas for crowd control or 'non-lethal' use.
