That’s called shooting a gun.
Precisely.
No that’s called a single action revolver without modern firing pin trigger safety block going off half cocked. This is the origin of the term going off half cocked. Original colt single action and their derivatives all share this safety issue. If the hammer is pulled back but is not engaged to the past the half cocked or full cocked sears and it is released it will under spring pressure fall back forward with considerable speed usually enough when the foreign pin is struck to light off the cartridge. This is also why historically 6 shot single action revolvers where carried with one empty chamber and that chamber was under the hammer. When on horse back if brush or something caught the hammer while on the leg holster and it let go of the hammer before it made it back to a cocked on sear position the gun would discharge right down ones leg. Modern revolvers be it single or double action all now have some means of trigger actuated fireing pin block typically this is a rotating block that disconnects the hammer end of the firing pin from the primer end not until the trigger is fully pulled does the block rotate fully to allow the two ends of the firing pin to transfer force to the primer. 1860 ers single action revolvers lack this as do all of their period accurate clones. This firearm is a period accurate clones of a 1860s era single action it absolutely will go off half.cocked and there should have been a detailed safety still conducted to highlight this danger.
Went off half cocked. Should have not had a round in the chamber. Not a live round!
