The opening shows two people with swords, two with lightning, and two with guns. I wouldn't say that during the war with the Grimm, they were able to mix swords and Dust together and may only used small amounts of Dust as gunpowder. Even the modern weapons we have seen don't seem to use Dust to increase the power of the blade, with the exception of Weiss' rapier.
