Nominally based on a real bounty hunter, The Deadliest Profession has Tiny Boyles hired to wipe out a Mormon splinter cult. He recruits several of his friends, arms up a Winnebago, and drives out into the desert. Before you know it, they're mowing down fleeing women, shooting them in the backs with machine guns.
The book is kept aloft by the witty banter, which actually works, rather than the clumsy action sequences.
Tiny predated Richard Marcinko and Kinky Friedman in the Real Life Character in Fictional Adventure sub-genre. Tiny is an interesting dude, but the actual adventure is below average men's paperback fodder.
