Griffin is a steampunk style pump-action shotgun made of wood, brass and steel or iron. The barrel is shrouded and expands outward at the end like a trumpet, complete with three petals that play sound when manually pushed in. Metallic teeth are attached on top of the pump handle, forcing a cog to rotate when a new round is being chambered. An external hammer is used to detonate the shells. The magazine is almost completely covered by the magazine well.
