Describe the term “double action” in handguns.

The term "double action" in handguns refers to a mechanism where pulling the trigger performs two actions: it first cocks the hammer and then releases it to fire the round. This means that the shooter can fire the handgun without needing to manually cock the hammer each time, which is a distinct advantage in situations where rapid follow-up shots may be necessary. The design allows for both convenience and a potentially quicker response time when handling the firearm.

This mechanism is contrasted with single-action systems, where the hammer must be cocked manually before the trigger can be pulled to fire. Thus, the double action feature is integral for those who prefer a more streamlined operation in their handgun use.
