Combination style weapons like the ones in RWBY aren't used IRL because they generally don't function well. The gun mechanism makes the blade heavy and the shock of striking with the blade can mess with the gun mechanism. But sometimes you just find a crazy combination weapon and appreciate that someone made it.

I know of a few, but I recently found this 16th century thing from Czechia. Introducing the Paladin starter pack, it's a meat cleaver, pistol, and calendar of saints all in one.
