Juliette is probably just a human with some fighting experience. As we know from this episode, not all humans with skills are actually Wesen. We don't know about Juliette's past, i.e. whether or not she learned how to fight or shoot (I think she'd never shot a gun before). Or maybe she's just naturally gifted and smart.
