As a safety precaution when carrying a revolver, what should the hammer always be resting on?

When carrying a revolver, it is crucial that the hammer rests on an empty chamber. This practice is vital for safety, as it prevents the firearm from accidentally discharging if the gun were to be dropped or if the trigger were to be inadvertently pulled. By ensuring that the hammer is on an empty chamber, you minimize the risk of an unintended discharge, which can lead to dangerous situations, injuries, or fatalities.

This approach aligns with standard safety protocols in the handling of firearms, which emphasize the importance of keeping the gun in a condition that reduces the chance of accidents. In addition to resting the hammer on an empty chamber, responsible firearm handling also involves being aware of the firearm's condition at all times and following the basic rules of firearm safety.
