Are Striker-Fired Pistols Double Action? Understanding Firing Mechanisms
The short answer is no, striker-fired pistols are not double-action. However, the distinction requires understanding the different firing mechanisms and how they function. This can be confusing, as the terms "single-action" and "double-action" are often applied differently to striker-fired pistols than they are to hammer-fired pistols.
Let's break down the terminology and clarify the mechanics:
Hammer-Fired vs. Striker-Fired: The Fundamental Difference
Before we address the double-action question, it's crucial to understand the core difference between hammer-fired and striker-fired pistols:
-
Hammer-Fired Pistols: These pistols use a separate hammer that strikes the firing pin. In a double-action hammer-fired pistol, cocking the hammer and releasing it fires the round. In a single-action hammer-fired pistol, the hammer is already cocked, and only the trigger needs to be pulled to release it.
-
Striker-Fired Pistols: These pistols eliminate the external hammer. Instead, a spring-loaded firing pin, called a "striker," directly ignites the primer. The trigger's action directly causes the striker to move forward.
Why Striker-Fired Pistols Aren't Considered "Double Action" in the Traditional Sense
The term "double-action" typically refers to the hammer-fired mechanism where one pull of the trigger both cocks the hammer and releases it to fire the round. Since striker-fired pistols lack a separate hammer, this definition doesn't apply.
However, some people might informally refer to the action of a striker-fired pistol as "double-action" because the trigger pull performs two actions:
- It cocks the striker (compresses the striker spring).
- It releases the striker to fire the round.
This is technically incorrect based on the traditional definition, but the parallel is understandable.
Key Characteristics of Striker-Fired Pistols:
- Simpler Mechanism: Fewer moving parts lead to enhanced reliability and easier maintenance.
- Consistent Trigger Pull: The trigger pull weight is generally consistent for each shot.
- Concealed Carry Advantages: The lack of an external hammer makes them easier to draw from a holster without snagging.
- Often Lighter Weight: The absence of a hammer can contribute to a lighter overall pistol weight.
Understanding the Terminology: Avoiding Confusion
To avoid confusion, it's best to use precise terminology. Instead of incorrectly labeling striker-fired pistols as "double-action," describe them as having a single-action-only mechanism that involves a striker instead of a hammer. This accurately reflects the mechanical operation.
In summary, while the trigger pull in a striker-fired pistol performs two actions, functionally making it similar to a double-action hammer-fired gun, it is not a double-action pistol according to the established definition. The lack of a separate hammer fundamentally differentiates the two firing mechanisms. Understanding this distinction is key to properly categorizing and understanding handgun operation.
