Western sitcoms don't seem to last very long. Don't ask me why, it just is.
One such example was Pistols & Petticoats, which ran for one season (1966-7), and might be better known as Ann Sheridan's last series. The comedienne passed away during the season, and it was decided to cancel the series after 1 season rather than try to continue with another actress.
Sheridan played Henrietta Hanks, who, along with her grandparents (Douglas Fowley & Ruth McDevitt), helped clean up the small town of Wretched, Colorado, providing some backup for the town sheriff (Gary Vinson, fresh from McHale's Navy).
Following is a sample episode, "Shootout at O'Day Corral":
Producer Joe Connolly was on his own for a change, after producing Leave it to Beaver, Calvin & The Colonel, and the show Pistols replaced at CBS, The Munsters, with Bob Mosher. Unfortunately, it would also be Connelly's last series for a while.
