 CONT: Numerous times during the season, when Jack pulls out his gun,  you can readily hear the click that indicates that the hammer has  been pulled back or cocked. However, in numerous other shots  throughout the season, it is very clear that the gun doesnt even  have a hammer to begin with. This is because it is a DAO or Double  Action Only pistol which means it doesnt have a protruding hammer  like Single Action (SA) or Double Action (DA) pistols do. The gun is  able to be fired with just a trigger pull rendering the manual  cocking of the hammer useless. So why do we keep hearing these  clicks of Jack cocking the non existent hammer?
