When does the unlocking step of a single action firearm occur?

The unlocking step in the operation of a single action firearm is a critical phase that occurs specifically after the trigger has been pulled. In a single action firearm, pulling the trigger releases the hammer or firing mechanism, allowing it to strike the firing pin and ignite the cartridge.

This firing process initiates the unlocking of the action, where the firearm’s mechanism disengages to allow for the extraction and ejection of the spent cartridge case once the round has fired.

While the firearm is being prepared for firing (before the trigger is pulled), it remains in a locked state. The resetting of the trigger, which occurs after the firing sequence, is a separate step that allows the firearm to be ready for the next shot. Therefore, it is the action of pulling the trigger that unlocks the firearm, which makes it clear that the unlocking occurs specifically after the trigger is pulled, aligning with the correct answer.

Understanding this step is essential for proper functioning and safety during the operation of single action firearms.
