We saw him using it as a trumpet, but he never transformed it into the gun mode. So, it's a blow dart in gun mode?

Mostly, although I can't imagine it is entirely breath dependent. As air dust exists, there must be an alternate channel he can activate to fire without his breath... unless his breath is the actual weapon and all the trumpet does is channel the harmful force into deadly force.

Alternatively, the breath could be entirely superfluous and the mouth guard just a really odd safety for the weapon... though Remnant has little reason to employ such safety systems given that the existent threat of Grimm could make another person using it a literal life-saver.
