What sounds indicate proper engagement when the trigger is pulled after releasing it?

The presence of a click from the hammer when the trigger is pulled after being released is a strong indication of proper engagement within the firing mechanism of the firearm. This click signifies that the hammer has moved into position and has engaged appropriately with the sear, which is essential for the firearm to function correctly. It reflects that the internal components of the firearm are operating as intended, ensuring that when the trigger is pulled back, the hammer is ready to strike the firing pin effectively.

A loud bang or a discharge of the cartridge are sounds that occur when the firearm is actually firing, rather than indicating engagement after the trigger has been released. Additionally, the absence of sound might suggest a malfunction or an incomplete cycle of operation, as there should generally be an audible cue, like a click, indicating that everything is functioning correctly at that moment. Thus, recognizing the click from the hammer as the appropriate sound helps in confirming that the trigger mechanism is interacting as designed, laying the groundwork for successful operation of the firearm.
