The Good Samaritan is a fictional weapon from Mike Mignola's Hellboy comics. The Samaritan is an oversized, uniquely large caliber four-round revolver. It fires its custom-made bullets with adequate power to easily penetrate virtually any material. The gun itself has unearthly resistance to almost all forms of attack, and includes grips carved from fragments of the True Cross. The metal of the gun is forged from a combination of Irish church bells, cold iron from crucifixes, blessed silver, and other mystic metals-wiki
