Does anyone know of any western novel series like this? (Click for details)?

So I ve read many westerns, and usually they are about a lone gunman (sometimes two or three) against the villainous gang leader. Usually, the gang leader, and perhaps his right hand man, are the only ones that get much attention or depth.

So I m looking for a series of western novels that follows a group of people, preferably a gang, that focuses on all (or many) members of the group, following them all through their adventures. Rather than just focusing on just two or three characters.

If anyone knows of any western novel series like this, I would greatly appreciate it!
