What is a unique name for a monster hunting gun?

I'm trying to name a gun (it's modeled after a desert eagle) that when fired only injures inhuman ';monsters'; such as vampires, werewolves etc. I want the name to have a mythical feel. Real names are welcome as well as names like ';Vampire killer';(from Castlevania) or ';Bloody Rose'; (Vampire Knight).What is a unique name for a monster hunting gun?

What color is it? If it was silver, for example, you could call it something like Silver Slayer. If it was black, it could be called something like Black Blood or Black Death.





Some other names that come to my mind:


Blood(y) Bullet


Crimson Trigger


Death Reaper


Slaying Eagle (based on the gun's model)


Sin Slayer





Best wishes!
';The Clergy'; which is another name for church leaders which would traditionally be a part of dealing with these creatures in many such worlds.





'; The Clergy barked three times,and three demons fell before me like so many cut string marionettes. Bleeding and silent. I love this gun.';
Law Claw ok not so much.





The Decider since it decides who is a monster and who isn't.
