Well, we've established how Ruby uses Crescent Rose against humans thanks to Episode 1: She uses the blunt guard at the top of the blade, the shaft and also uses the weapon as a pivot for double-footed kicks.

She isn't afraid to use the gun mode against humans though. She fired at least three shots directly at Crimson and, if the latter hadn't had a shield spell handy, those would have probably been maiming or even lethal shots. Of course, by this point, Crimson had fired enough lethal magic at Ruby and Glinda that the girl probably had reason to believe that her life was in peril, hence her willingness to use lethal force.
