They Call Me Trinity
The devil's right hand is called Trinity. He himself claims to be a man of peace, but he is anything but that. He comes to a town where his brother Bambino is the sheriff. But in fact, his brother is a robber who killed the real sheriff and then took his place. Together, Trinity and Bambino decide to help a group of Mormon settlers from being driven away by a wicked landowner in this western from 1970.
