To test if the action mechanism is functioning, what should happen when the trigger is continuously depressed during cycling?

In the context of testing the action mechanism of a firearm, a click being heard when the trigger is continuously depressed during cycling indicates that the mechanism is functioning properly. This click typically signifies that the sear has released the hammer or striker, which is an essential part of the firing cycle.

When the trigger is pressed and held, the intent is to determine if the internal components are moving as they should. Hearing a click is a positive indication that the firearm's action is interacting correctly—the hammer or striker is being released as intended in response to the trigger pull. This click is an auditory confirmation of the internal mechanism's operation, which is crucial for ensuring the firearm operates safely and reliably.

Other responses reflect different scenarios that do not necessarily indicate proper functioning. For instance, if the hammer were to fall gently, it could suggest issues with the sear engagement that may not be correctly interfacing with the hammer—this would not align with the expected behavior when the trigger is continuously depressed. Likewise, if the cycle were to complete without issues, while it suggests functionality, it lacks the specificity of the audible click, which directly indicates that the action mechanism is responding correctly to the trigger engagement. If nothing happened, it would indicate a failure in the firearm's ability to
