Don't forget the "
Powder Valley Western" series by
Peter Field [Brett Halliday].
Apparently, there are
63 books in the series, but I only have 10 of them.
I read these back when I was about 12 or 13 years old and loved them.
Check out this link for more of his great Westerns, and his many pseudonyms (and other Westerns):

And if you like detective fiction, then check out his
Mike Shayne series.
