I am a minister and a western history buff and reenactor. There are two books out there that I've just finished for a circuit rider portrayal I do. One is called "Bible in pocket, Gun in Hand" and the other is "Pistol Packin' Preachers". Now, if you love the old west, you don't have to be a Christian to really enjoy these true stories. None of the folks were wimps and took no gruff from anyone. They are very good reads and shows there were tough men out there besides lawmen and outlaws, cattlemen and miners. The guns they prefered might surprise you, Pale Rider may have been a little more authentic than many believe...
