What Is the Hand?

The hand (also called the pawl or cylinder hand) is a critical internal component of the revolver's action. It engages the cylinder ratchet and rotates the cylinder to the next chamber with each trigger pull or hammer cock. A worn or damaged hand can cause cylinder timing issues, misfires, or failure to rotate — making this a key part for any revolver restoration or repair.
