Blood Forged – Kathryn Meyer Griffith

Blood Forged by Kathryn Meyer Griffith:
An ancient snake-demon lies trapped behind the stone walls of an Incan prison; for centuries demanding blood sacrifices and scheming to escape. Then it discovers a pathway into the world of men, forging itself into a malevolent and cursed 357 Colt Python gun, and making itself capable of giving misery and bringing death to all who touch it. Through decades it torments, decimates, the lives of the unfortunate people it comes into contact with until a married couple, Emily and Sam Walters, have enough love and faith–and the help of a mysterious priest who’s much more than he appears to be–to fight against and destroy it forever…and to finally send it back to hell where it belongs. (Originally a Leisure mass market paperback titled Blood Forge.) ***
