DOUBLE ACTION Meaning and
Definition
-
Double action is a term primarily associated with firearms and describes a mechanism in which a single pull of the trigger performs two separate actions in order to discharge the firearm. In a double action firearm, the trigger pull accomplishes both the cocking of the hammer or striker and the releasing of it to strike the firing pin or primer, thus firing the weapon. This differs from single action firearms where the trigger merely releases a pre-cocked hammer or striker.
The double action mechanism provides several advantages in terms of firearm operation and safety. First, it allows for the firearm to be carried safely with a round loaded in the chamber, as the trigger pull requires a deliberate and significant force to discharge the weapon. This adds a layer of protection against accidental discharges. Second, it eliminates the need to manually cock the hammer or striker, allowing for a quicker and more fluid action. Lastly, in the case of a misfire or failure to fire, the shooter can simply pull the trigger again to attempt a second strike on the primer, potentially causing ignition and firing of the round.
Double action firearms are frequently found in handguns, and they are commonly used by law enforcement officers, military personnel, and self-defense enthusiasts due to their reliability and ease of use.
Etymology of DOUBLE ACTION
The term "double action" originates from the combination of two separate words: "double" and "action".
The word "double" comes from the Old French term "doble", derived from the Latin word "duplus", meaning "twofold" or "double". It entered English in the 14th century and was used to describe something that has two parts, components, or functions.
The word "action" also has Latin roots, derived from the Latin word "actio". It was used in Middle English to refer to the process of doing something or taking measures. In this context, it relates to the functioning or operation of a mechanism.
When these two words are combined, "double action" refers to a mechanism, especially found in firearms, that allows for two distinct actions or functions to be performed with a single operation.
