Fargo is a mercenary for hire who signs up for a seeming suicide mission bringing a load of silver out of revolution-torn Mexico in Fargo, the first in a series by prolific, pseudonymous scribe John Benteen.
Not long ago I read The Trail Ends in Hell by Benteen, aka Ben Haas, a sturdy little Western that interested me in finding more of his writing. However, despite Fargo's trappings I would say it was more Men's Adventure than Western, not only in its time period (early 20th century) and focus on action, but also in its casual handling of women and fetish-like attachment to weapons.
Benteen again writes a solid story, and I must not have been the only one that thought so as the Fargo series went on for some time throughout the 60s and 70s. I was able to get a handful at a flea market and I am sure I will jump on another one before long.
