What is indicated if the trigger does not reset during a revolver's operation?

The scenario where a revolver's trigger does not reset during operation typically indicates a malfunction with the trigger spring. The trigger spring plays a crucial role in returning the trigger to its original position after being pulled. If the spring is damaged, weakened, or broken, it may not have the necessary tension to push the trigger back to the reset point after firing, which directly affects the functionality of the firearm.

Additionally, in the context of revolvers, when the trigger fails to reset, it can hinder smooth and continuous operation, preventing the shooter from firing subsequent shots efficiently. This malfunction can lead to a misfire or require manual intervention to reset the trigger, which is undesirable in a firearm’s operation.

Other factors like cylinder alignment or a locking mechanism failure could cause issues in operation, but they would present different symptoms. For instance, a cylinder alignment issue might prevent the cylinder from rotating properly, and a locking mechanism failure would inhibit the hammer or firing pin from functioning correctly. However, both would not specifically prevent the trigger from resetting. The trigger spring malfunction is the most direct cause of the problem stated in the question.
