Understanding the Core: Double Action and Striker-Fired Unveiled
Double Action (DA) Mechanism
At the heart of the double action striker fired design lies a fusion of two distinct yet complementary technologies: the double-action trigger and the striker firing system. To fully grasp the functionality and impact of these pistols, it is crucial to first understand each component separately.
The double-action trigger represents a fundamental approach to firing mechanism. In essence, a double-action trigger performs two crucial functions with each pull. First, it cocks the firing mechanism, essentially preparing the gun for firing. This action can range from simple cocking to more complex operations that may involve compressing a spring. Second, it releases the firing mechanism to strike the primer and ignite the cartridge. This complete cycle distinguishes a double-action trigger from its single-action counterparts, in which the firing mechanism (typically a hammer) is manually cocked beforehand. The signature characteristic of a double-action trigger is its relatively long travel distance and, typically, a heavier pull weight compared to single-action triggers. This feature often contributes to heightened safety, making accidental discharges less probable. The long and deliberate pull adds a layer of control, requiring the shooter to consciously and consistently apply pressure to the trigger.
Striker-Fired System
The striker-fired system presents a different approach to the firing process. Rather than employing a hammer, this system utilizes a spring-loaded firing pin, known as the striker. When the trigger is pulled, the striker is released, traveling forward to strike the primer of the cartridge and initiate ignition. The inherent simplicity of the striker-fired system is often cited as an advantage. Fewer moving parts contribute to increased reliability, as there are fewer components that can potentially malfunction. The streamlined design also results in a slimmer profile, potentially improving ergonomics and aiding in concealed carry. The absence of an external hammer can reduce the chance of the pistol snagging on clothing or other objects during the draw.
Combination: Double Action and Striker Fired
When these two concepts converge, the result is a double action striker fired pistol. Here, the trigger pull initiates both the cocking of the striker and its subsequent release, resulting in the firing of the pistol. The trigger pull is typically characterized by a long, deliberate motion and a moderate-to-heavy weight. The design inherently incorporates a high level of built-in safety, as the long pull adds an element of intentionality to each shot.
Key Features and Design Elements: Dissecting the Mechanism
Trigger Mechanism
The design of a double action striker fired pistol presents several key considerations that affect its handling, performance, and overall user experience.
The trigger mechanism is paramount in defining the feel and operational characteristics of these pistols. The trigger pull itself—specifically, its weight, length of travel, and reset—plays a decisive role in accuracy. A heavier trigger pull, for example, can make it more difficult to maintain a consistent sight picture, potentially affecting shot placement. The length of travel, or the distance the trigger moves before firing, impacts the shooter’s ability to manage recoil and make quick follow-up shots. Trigger reset, which is the distance the trigger needs to travel forward to re-engage the firing mechanism, is also important. A shorter reset allows for faster follow-up shots. Variations in trigger design may include pre-travel (the distance the trigger moves before engaging the sear), over-travel (the distance the trigger moves after the shot is fired), and the overall feel of the trigger.
Safety Features
Safety features are also integral to these pistols. Internal safeties, which operate automatically, are commonplace. These can include a firing pin block that prevents the striker from moving forward unless the trigger is pulled, and a drop safety that safeguards against accidental discharge if the pistol is dropped. External safety options, like manual safety levers or grip safeties, are sometimes incorporated. These features allow the user to manually prevent the pistol from firing. The presence of these different safety mechanisms adds a layer of control for the shooter, enhancing the firearm’s safety profile, and making it suitable for a wide range of carry situations.
Ergonomics and Handling
Ergonomics and handling are further design aspects. The design of the grip, how it fits in the hand, is a key factor in shootability. A well-designed grip provides a secure and comfortable hold, enabling the shooter to effectively manage recoil and maintain control of the firearm. The contours and texturing of the grip surface determine the degree to which the pistol feels comfortable and safe in the hand. Sights, which allow the shooter to aim the weapon, are another crucial consideration. Sights come in various forms. They can be basic, such as the standard three-dot configuration, or more sophisticated, such as those with tritium inserts for low-light conditions. The overall balance and feel of the pistol, taking into account weight distribution, greatly affects how quickly and accurately a shooter can get the gun on target and stay on target. Magazine capacity, affecting how many rounds can be carried, also makes a difference.
Advantages of the Double Action Striker Fired
The double action striker fired pistol presents a set of notable advantages. These make it attractive to a variety of gun owners.
Safety
Safety is perhaps the most frequently cited benefit. The longer trigger pull inherent in the design of these pistols inherently provides a measure of protection against accidental discharges. This is because it requires deliberate and conscious effort to fire the weapon. The multiple internal safeties, common in many double action striker fired designs, further reinforce the safety profile. This makes these pistols a popular choice for concealed carry, where a high degree of safety is essential.
Simplicity and Reliability
The simplicity and reliability of the design is also a factor. The streamlined mechanism, with its fewer moving parts compared to traditional hammer-fired double-action pistols, can contribute to increased reliability. The absence of a hammer can also prevent potential mechanical failures, making it a solid option for personal defense.
Concealed Carry Considerations
The overall suitability of these pistols for concealed carry is worth noting. Their inherent safety features, the absence of a snag-prone external hammer, and their typically streamlined designs contribute to a more discreet and secure carry experience.
Disadvantages to Consider
While the double action striker fired pistol offers advantages, it also presents certain trade-offs.
Trigger Pull
The trigger pull is a key factor. The long and often heavy trigger pull can be a detriment to accuracy, especially for shooters who are accustomed to lighter, crisper triggers. This can make it more difficult to achieve precise shot placement, particularly at longer ranges. The nature of the pull also makes it difficult for shooters to make quick follow up shots.
Learning Curve
The learning curve for shooters is also a point of consideration. The long trigger pull requires a significant amount of practice to master. Those transitioning from other types of pistols, particularly those with single-action triggers, may need time to adjust their shooting technique to accommodate the double action striker fired trigger. As a result, these pistols are not necessarily the best option for beginners.
Potential for Reduced Accuracy (Initial Impact)
The potential for reduced accuracy, especially upon initial use, is another aspect. The long trigger pull can introduce unwanted movement into the shooting process, making it more difficult to maintain a consistent sight picture. This, in turn, can lead to decreased accuracy.

Contrasts: The Double Action Striker Fired Against Other Pistol Types
To fully appreciate the role of the double action striker fired pistol, it’s helpful to compare it to other common pistol types.
Double Action/Single Action (DA/SA) Pistols
DA/SA pistols feature a hammer and allow the shooter to fire the first shot in double-action mode, meaning the trigger pull both cocks the hammer and fires the pistol. Subsequent shots are fired in single-action mode, where the hammer is pre-cocked, resulting in a lighter and shorter trigger pull. While DA/SA pistols offer the potential for a lighter single-action trigger pull, the transition from the heavier first shot to the lighter subsequent shots can be a challenge for some shooters. In the double action striker fired design, the trigger pull remains consistent for every shot.
Single-Action (SA) Pistols
Single-action pistols, such as the classic 1911, require the hammer to be manually cocked for each shot. This results in a very light, crisp trigger pull. The primary advantage of single-action pistols is the potential for superior accuracy and faster follow-up shots. However, the reliance on manual cocking means a less safe carry for some.
Other Striker-Fired Designs
The double action striker fired pistol is distinct from other striker-fired designs, like those that are pre-cocked or partially pre-cocked, resulting in a lighter trigger pull, more similar to single-action systems. These types tend to be more popular.
