on hellboy...
Hellboy holds his the Good Samaritan with his left hand because the fingers on his right hand cannot hold it properly. The Good Samaritan only holds four bullets, and The Good Samaritan's grip is carved from fragments of the True Cross while the metal of the gun is forged from a combination of Irish church bells, cold iron from crucifixes, blessed silver, and other mystic metals while its "creature killer" bullets are tipped with explosive shells that contain white oak, holy water, garlic, silver and cold iron shavings; sufficient to kill a werewolf.
