God's Gun (1976)

Intent on murder, the vicious cut-throats of the pitiless bandit, Sam Clayton, ride into dusty Juno City, rob the bank, and kill the pacifistic man of religion, Father John, in front of the church. As the semi-inebriated sheriff decides not to take action, the priest's young protégé, Johnny, gambles with death to find the deceased's twin brother, Lewis, in Mexico, and talk him into settling the score. Can Diamante Lobo, the feared ex-bounty hunter, right a wrong, and in the process, rid the town of Clayton's jackals?
