Sear shown in a revolver action. In a firearm, the sear is the part of the trigger mechanism that holds the hammer, striker, or bolt back until the correct amount of pressure has been applied to the trigger, at which point the hammer, striker, or bolt is released to discharge the weapon. The sear may be a separate part or can be a surface ...
The click is the sound of one end of the sear engaging in the blind hole on the inside of the wheel, thus immobilising it. The pan is then primed with powder, and the pan cover pulled shut. Finally the dog is pulled back so that the pyrite in its jaws is resting on the top of the pan cover, under some pressure from the spring at the toe of its arm.

Also like the wheel-lock, the snaphance used a lateral sear mechanism to connect the trigger to cock. Later models had a variety of safety mechanisms to prevent accidental discharge of the gun.
When an automatic sear is in place, the weapon’s trigger bar is prevented from catching its firing pin, allowing multiple rounds to be fired without additional pulls of the trigger.
The flash pan was at first attached to the gun barrel, but was later moved to the lock plate of the gun. A small amount of finely ground gunpowder is placed in the flash pan and ignited. The flash of flame travels through the touch hole igniting the main charge of propellant inside the barrel. Unlike the cannon, it was not necessary (or ...
The sear is a "catch" or "latch" which holds the mechanism in a position ready to fire; the trigger acts upon, or is part of, the sear, releasing it and allowing a strong spring to act on the mechanism to fire the gun. Previously the sear, located within the lock, had acted through a hole in the lockplate to engage the cock on the outside of ...
