Early revolvers were single action- you had to cock the hammer manually, then pull the trigger. An example would be the Colt Peacemaker. A double action revolver (such as a S&W 357 magnum- Mdl 66) can be fired by pulling the trigger. Trigger pull, by itself, will cause the hammer to rise and fall. OR- the hammer may be cocked, and then the trigger pulled. A "DAO" or double action only, the hammer cannot be cocked, and the gun must be fired by pulling the trigger.
Single Action requires the hammer to be cocked before pressing the trigger to fire the weapon. Double Action only requires you to press the trigger through its range of motion.

A double action gun is a revolver that provides the ability to fire the gun no matter whether the gun is cocked or not cocked. Manually cocking the gun by pulling back the hammer or just by pulling the trigger will rotate the cylinder to the next round or shell.. A double action may be a revolver or a semi automatic pistol . As long as there is a round in the chamber all need be done is to squeeze the trigger to fire the weapon . A single action requires you to have the hammer pulled back already to squeeze the trigger and have the weapon fire .

Double Action pistols may not HAVE a manual safety. Like a double action revolver, the trigger must move through a long and deliberate arc for the gun to fire. Not all guns have had a safety.
