Understanding the Significance of Trigger Pull Weight
For the dedicated shooter, the feel of the trigger is paramount. It’s the gateway to accuracy, the critical link between intention and outcome. Every element contributes, from the ergonomics of the grip to the crispness of the break. But perhaps no single factor impacts performance more directly than the trigger pull weight. With this in mind, you might be asking yourself, *can I control trigger pull weight on a 686*?
The Smith & Wesson Model 686 is a legendary revolver. Esteemed for its rugged build, exceptional accuracy, and enduring reliability, it’s a favorite among target shooters, hunters, and those seeking personal protection. The 686’s robust frame and smooth action make it a joy to shoot. However, like all firearms, the factory trigger pull can be refined to match an individual’s preference and shooting style. We’re going to explore how you can potentially influence the trigger pull weight on your 686, delving into the methods, the associated considerations, and everything you need to know.
The phrase “trigger pull weight” refers to the amount of force required to actuate the trigger and subsequently fire the firearm. It’s measured in pounds (lbs). A lighter trigger pull generally means less force is required to initiate the shot, which can be beneficial for accuracy, especially in DA/SA revolvers. Conversely, a heavier pull can make it more challenging to maintain a steady hold, leading to unintentional movement and decreased precision. A well-tuned trigger is an essential component of accurate shooting.
The 686 typically operates in a double-action/single-action (DA/SA) mode. When firing in double-action, pulling the trigger both cocks the hammer and then releases it, resulting in a longer, heavier trigger pull. In single-action mode, the hammer is manually cocked, allowing for a shorter, lighter pull. The distinct action types directly influence trigger feel.
Factory trigger pull weights for the 686 can vary slightly depending on the specific model and manufacturing tolerances. Typically, a 686 will have a double-action pull weight ranging from approximately ten to fourteen pounds. The single-action pull weight will usually fall within a much lighter range, often between three and five pounds. Being able to refine these is key to fine tuning your 686.
Approaches to Modify Trigger Pull Weight
So, *can I control trigger pull weight on a 686*? The answer is, potentially, yes. Several strategies can be employed, though it’s important to remember that firearm modification can impact safety and performance. Always proceed with caution and, if unsure, consult a qualified gunsmith.
One common method involves spring replacement. Within the 686, there are two springs, in particular, that can have a significant impact on the trigger pull.
Hammer Spring
Replacing the hammer spring with a lighter-weight version is the most direct method to decrease the trigger pull weight in both double-action and single-action modes. A lighter spring requires less force to compress, thus reducing the pull weight. The trade-off here is ensuring reliable ignition of the primer. With a lighter spring, there’s a greater chance of a “light strike,” where the primer isn’t adequately ignited, resulting in a misfire.
Trigger Return Spring
While less impactful on overall weight, the trigger return spring also plays a role. A lighter trigger return spring can improve the feel and sometimes subtly reduce the overall trigger pull weight by decreasing the force needed to reset the trigger.
When considering spring replacements, choose high-quality springs specifically designed for the 686. Poorly made springs may break prematurely or compromise the gun’s reliability. It’s also crucial to test the firearm thoroughly after replacing any springs to ensure proper function and primer ignition.
Another approach is polishing internal parts. This involves carefully smoothing and removing imperfections from the surfaces of key components, thus reducing friction. Minimizing friction allows the parts to move more smoothly, which can lead to a perceived reduction in trigger pull weight. The key components include:
Sear
The sear is the part that engages the hammer and prevents it from firing until the trigger is pulled. Polishing the sear mating surfaces can create a cleaner, crisper break.
Hammer Face
Polishing the hammer face, where it contacts the firing pin, can decrease friction.
Trigger
Polishing the trigger components, specifically the areas that interact with the sear and the frame, can help the trigger slide more smoothly.
Polishing, when done correctly, can enhance the trigger’s feel without significantly altering the pull weight. The polishing process typically involves using specialized polishing compounds and tools to gently remove any burrs or imperfections. It’s essential to disassemble the appropriate parts, meticulously polish them, and then reassemble the firearm, taking care to avoid altering any critical angles or surfaces. Always remember safety glasses when polishing or working on your firearm.
For many, the safest and most effective route is to entrust a professional gunsmith with modifying the trigger. Gunsmiths possess the expertise, specialized tools, and experience necessary to perform custom trigger jobs. Their modifications can encompass a wide range of improvements, from basic action smoothing to more advanced sear work and spring tuning.
Custom Trigger Jobs
A professional gunsmith can assess your specific 686, identify areas for improvement, and create a trigger job tailored to your preferences. This might involve polishing, spring replacement, adjusting the engagement surfaces of the sear and hammer, and refining the trigger mechanism.
Expertise and Precision
Gunsmiths bring years of experience and a keen eye for detail. They understand the intricate mechanics of the 686 and can make precise adjustments without compromising safety or functionality.
Cost and Timeline
A professional trigger job will typically involve a cost. The price depends on the complexity of the work. It’s often a worthwhile investment to improve the overall shooting experience. The turnaround time can vary. Discuss the scope and timeline with the gunsmith upfront.
There might be some other adjustments that can be considered for your 686. Research into shimming certain internal components could reveal another avenue that you could take.
Influencing Factors on Trigger Pull Weight
Even after any adjustments, several other factors can influence trigger pull weight. These should be taken into consideration when you ask yourself *can I control trigger pull weight on a 686*?
The type of ammunition you use plays a significant role. Ammunition with harder or softer primers may affect the reliability of ignition, especially after modifications. Lighter hammer springs might be adequate for softer primers, but may cause misfires with harder primers. Using quality ammunition appropriate for your firearm is essential.
Maintenance is critical. Regular cleaning and proper lubrication of the 686’s internal components minimize friction, which can lead to a smoother, lighter trigger pull. Neglecting maintenance can cause a heavy, gritty trigger.
Wear and tear over time can also influence trigger pull weight. Repeated use can slightly alter the mating surfaces of internal components. Regular inspection and maintenance can help mitigate this. If wear becomes significant, replacement parts might be needed.
Safety, Legalities, and Professional Guidance
When considering any modifications to your 686, safety must always be the top priority. Always unload the firearm and verify that it’s clear before commencing any work.
It’s important to be aware of any local regulations regarding firearm modifications. Some jurisdictions may have restrictions on altering trigger pull weight. Research and understand the laws that apply to your location.
If you are unsure about any aspect of modifying your 686’s trigger, it’s wise to consult with a qualified gunsmith. Trying to work on the firearm without the proper knowledge or tools can be dangerous. A gunsmith can assess your firearm and provide expert guidance.
After any trigger work, it’s crucial to perform thorough testing. Test-fire the gun to ensure that the trigger functions reliably, that it’s safe, and that primers are properly ignited.
In Conclusion
In summary, *can I control trigger pull weight on a 686*? The answer is a qualified yes. You can potentially influence the trigger pull weight through several methods. Spring replacement is a direct approach, while polishing internal components can reduce friction. Professional gunsmithing offers a more comprehensive solution. However, factors like ammunition, maintenance, and wear also play significant roles.
