Odds are very good that the leaf spring on the cylinder pawl has broken, a common occurence. Point the gun straight down, and see if the cylinder then operates correctly. We used to run our old Ubertis for months with a broken pawl spring by simply developing the habit of pointing them down when cocking for the next round.
Preventative measures include de-burring and smoothing the channel in the frame in which the pawl operates, polishing the spring at it's contact point, and keeping it all well oiled.
