Not gunslingers but the more dignified title of “Range Detective” to ride the range in the employ of the rancher for the purpose of protecting & defending the livestock . It’s for the purity & safety of the food supply don’t you know.
Right.It has been a long time since I saw an old fashioned shoot=em up. Guys like Charles Starrett used to hired out as range detective to catch rustlers working for guys in town who wanted to take over the range.
