Double Action

 An action type, typical on handguns, where the hammer may be cocked manually prior to each shot, OR one may pull the trigger through a long throw which cocks the hammer (and in the case of a revolver, advances the cylinder) and fires the revolver in one complete motion. Usually recognizable by the trigger position well forward in the triggerguard.

Single Action

An action type, typical on handguns, where the hammer must be cocked manually prior to each shot (if it be a revolver) or prior to the first shot with an already loaded chamber and de-cocked hammer (if it be a semi-automatic). Usually recognizable by the trigger position well rearward in the triggerguard.
