Stormflower, Ren's weapon, kind of uses the dagger-pistol idea, only his is a bladed smg.

Look, it doesn't have to have absolutely nothing in common with other weapons already seen in the show; there are so many different types of swords and rifles that even if you made a hundred weapons, I bet you could make a hundred unique combinations. So even if the base 'sword and rifle' are the same, the type of sword and rifle will be different, as will the mechanisms used for tranforming between shapes, the colours, the accessories, etc. It will be a unique weapon for the user.

After all, Yang and Mercury technically use the same weapon, shotguns, on different parts of their body. Doesn't make them any less unique. Fox and Miltiades Malachite both use claws, but they're still unique because of the design aspects of them.
