What is a common reason for a revolver failure to fire?

A common reason for a revolver failure to fire is indeed that the revolver is not loaded. If there are no cartridges in the cylinder, then pulling the trigger will simply result in the click of the hammer striking a chamber without a round, leading to a failure to fire. This highlights the fundamental requirement of ensuring that a firearm has ammunition before operation.

While other factors, such as a frozen cylinder or an uncocked hammer, can also lead to a failure to fire, these situations typically involve issues that can be remedied or checked mechanically. Conversely, if the revolver is not loaded, there is no opportunity for the firearm to operate as intended, irrespective of any mechanical conditions. Understanding the necessity of ammunition is vital for safe and effective firearm handling.
