The presence of two triggers on a handgun immediately sparks curiosity. While less common than single-trigger designs, double-trigger handguns exist, each with a unique purpose and history. This article delves into the reasons behind this design choice, exploring the functionality and historical context of these intriguing firearms.
The Two Types of Double-Trigger Handguns
Before understanding why some handguns have two triggers, it's crucial to clarify the types of double-trigger systems. Essentially, there are two primary categories:
1. Pre-World War II Double-Action/Single-Action (DA/SA) Designs:
Many older handguns, particularly those from the pre-WWII era, featured a double-action first trigger pull for the initial shot, followed by single-action subsequent shots. The first trigger pull cocked the hammer and fired the round, while subsequent trigger pulls only released the already-cocked hammer. This system was common in many revolvers and some semi-automatic pistols. The second trigger, in this case, was not a separate function but a change in the trigger's action.
2. Modern Double-Trigger Systems for Specific Functions:
Modern double-trigger handguns are far less common and usually serve highly specialized purposes. These are often found in niche applications, such as:
- Training Pistols: Some training pistols use a double-trigger system to teach proper trigger control and reset. One trigger might simulate a heavier, DA pull, while the other mimics a lighter, SA pull, allowing for more precise training.
- Specialized Law Enforcement/Military Applications: While rare in modern military and police arsenals, historically some niche applications involved double-trigger mechanisms for specific functionality. However, these applications are largely superseded by more streamlined designs.
- Custom Builds: Occasionally, gunsmiths create custom firearms with double triggers, often for novelty or specialized shooting disciplines.
Why the Decline in Double-Trigger Handguns?
The prevalence of double-trigger handguns has significantly decreased over time. Several factors contribute to this decline:
- Complexity and Maintenance: Double-trigger mechanisms are inherently more complex than single-trigger systems, potentially leading to increased maintenance requirements and higher chances of malfunction.
- Ambidextrous Use: Many modern firearms prioritize ambidextrous functionality. Double-trigger systems can be less adaptable for left-handed shooters.
- Ease of Use and Speed: Single-action or striker-fired designs generally offer faster and easier operation, providing a distinct advantage in self-defense or competitive shooting scenarios. The extra step of using a second trigger can slow down reaction time.
- Safety Concerns: While modern designs are engineered to be safe, historical double-trigger systems presented some safety challenges compared to modern single-action or striker-fired designs.
Conclusion: A Relic of History and Specialized Applications
In conclusion, the presence of two triggers on a handgun is a design choice rooted primarily in historical context, training applications, and niche specialized functions. While common in older designs, modern firearms largely favor simpler, more efficient single-trigger systems. Understanding the historical reasons behind the double-trigger system adds context to the evolution of handgun design and highlights the ongoing development of firearm technology. Remember that firearm ownership and usage are subject to specific regulations and require responsible handling. Always consult local laws and regulations before owning or handling any firearm.
