These Single Action Revolver replacement pins are oversized to reduce "cylinder wobble". The head has been redesigned for a more positive grip for easy removal, and is also shorter than the factory head to allow for longer ejector rod travel that improves ejection. Some applications may require minor fitting, depending on burrs in holes and hole alignment.
