Gun Battle at Monterey (1957)

Reno and Turner are partners who robbed the express in Monterey. But when Turner wants to leave the partnership, Reno shoots him and leaves him for dead. But Turner is found by Maria and nursed back to health. He then searches California for Reno and finds him in Del Ray, running a bar which he got by shooting his partner Abbott. Turner masquerades as York and keeps Reno off balance long enough to trap him.
