A Novel Of Outlaw Guns
I’m not sure if this is related to Sky Pilot or not.
From the back:
Galt Magrath was only a younker when a grizzled old cowpuncher called Hipshot rode up with the news that his father, Preacher Sam Magrath, had been bushwhacked by rustlers. With Preacher Sam’s Bible in one hand and a gun in the other, Galt roamed the Southwest with Hipshot, seeking to avenge his father’s murder. His search took him to Dodge City, where he met Bat Masterson and first saw the woman who was to lead him to the band of outlaws.
