Ruger Super Warhawk
From Nighthawks Shadowrun Wiki
Aka: Big Fragging Gun.
An old fashioned revolver with a six-shot cylinder and a 10M punch. Want something with permanent written all over it, off the shelf, without bothering with custom designs? Buy a Warhawk.
I know what you're thinking punk. You're thinking did he fire six shots or only five? And to tell you the truth I've forgotten myself in all this excitement. But being this is a .44 Magnum - the most powerful hand gun in the world and will blow your head clean off, you've got to ask yourself a question- Do I feel lucky?
- Well, do ya punk!
