When the trigger is pulled (or the hammer is pulled back), the HAND pushes against the STAR on the rear of the cylinder, causing the cylinder to rotate. The hand may be worn, the star may be worn, or the hand spring may be loose or broken, and is not moving the hand to the correct position. Any of the 3 are likely to require a gunsmith. In a few cases, dirt and carbon can build up on the star, causing the hand to slip. If a cleaning does not fix it, see a gunsmith.
1) ensure the revolver is unloaded and safe. 2) open the cylinder - Rossi marked their revolver model number on the frame behind the cylinder crane, ie: M31 etc.
