Understanding the M&P Trigger System
The Heart of the Action
The Smith & Wesson M&P pistol is a favorite among law enforcement, military personnel, and civilian shooters. Its reliability, modularity, and comfortable ergonomics make it a top choice. One area often customized is the trigger. This guide will delve into the M&P trigger to help you understand, maintain, and enhance your firearm’s performance.
From the first pull, the trigger links you to accuracy and control. A well-tuned trigger can improve shooting experience, allowing for faster follow-up shots, tighter groupings, and greater confidence. This guide will explore the nuances of the M&P trigger, answering your questions and providing insights.
The heart of any firearm’s action lies in its firing mechanism. The M&P, in its various iterations, employs a striker-fired system. Unlike hammer-fired pistols, which use a hammer to strike the firing pin, the M&P uses a spring-loaded striker. When the trigger is pulled, it releases the striker, which then strikes the primer of the cartridge, initiating the firing sequence.
The trigger connects to a trigger bar, interacting with the sear. The sear holds the striker cocked until the trigger is pulled. Upon pulling the trigger, the trigger bar moves the sear, releasing the striker. It’s a carefully orchestrated mechanical ballet, designed for reliable and accurate shots.
Delving into the Components
It is important to understand the various elements that comprise the M&P’s trigger system. Examining the trigger pull itself will allow you to understand how each individual part works to execute the shot.
The M&P trigger pull, measured in pounds, represents the force required to move the trigger and release the striker. The pull weight can vary depending on the generation of the M&P, aftermarket modifications, and the specific pistol model. Understanding this weight is key to optimizing the trigger.
Another important aspect of the M&P trigger is travel distance. This refers to how far the trigger must move backward before the striker releases. Along with trigger pull weight, travel distance influences how quickly follow-up shots can be fired.
A final consideration is reset. Reset is the distance the trigger must travel forward after firing before it’s ready to fire again. A shorter reset allows for quicker follow-up shots. Some shooters prefer an audible and tactile reset, while others prefer a smoother, less distinct reset.
Evolution of the Trigger
Considering the generations of the M&P, it’s necessary to understand how trigger design has evolved. The original M&P series had a good trigger, which was then improved. The M&P 2.0 brought several refinements to the trigger system, with the most notable change being a reduced trigger pull weight. These small improvements were geared towards helping the end user have better control while shooting. With various aftermarket trigger options, the shooter can choose the trigger design that best suits them.
Common Issues and Problems with the M&P Trigger
Grit and Friction
Even with its robust design, the M&P trigger isn’t immune to issues. Recognizing these problems and understanding their causes is crucial to keeping your pistol functioning optimally.
A gritty feel is a common complaint. This can manifest as a rough or uneven sensation when pulling the trigger. Several factors can contribute to this, including manufacturing imperfections, debris buildup, and the effects of dry firing without proper maintenance. Regular cleaning and lubrication can often resolve this issue. Polishing key trigger components can further improve the feel, leading to a smoother and more predictable trigger pull.
Pull Weight Concerns
Another frequent issue is a heavy trigger pull. A trigger pull that requires excessive force can negatively impact accuracy. Several issues can contribute to a heavy pull, like factory spring weights or excessive friction within the trigger mechanism. Solutions include the use of lighter springs, and trigger kits designed to reduce pull weight.
Reset Troubles
A long reset can be a problem, particularly for those who prioritize fast follow-up shots. A long reset can impede a shooter’s ability to fire quickly and effectively. The original trigger bar design in some M&P models can contribute to a long reset. Upgrades and modifications often include trigger bar replacements, which can shorten the reset distance.
Malfunctions
Malfunctions are another consideration. Hangups, failure to reset, and failure to fire can be concerning problems that require attention. Debris, worn-out parts, or other types of problems are the typical causes. Thoroughly cleaning and lubricating the trigger components on a regular basis are often sufficient. However, persistent problems may require parts replacement or professional gunsmithing.
Troubleshooting and Maintenance
Basic Care
Regular maintenance is key to keeping your M&P trigger functioning flawlessly. Many maintenance tasks are straightforward and can be performed at home.
Basic cleaning and lubrication is the foundation of M&P trigger maintenance. Disassembly, while potentially complex for beginners, is often necessary for thorough cleaning. Careful disassembly instructions can be found in the owner’s manual or online, and a detailed guide is available for nearly every model. Once disassembled, clean all trigger components, removing any accumulated dirt, debris, and old lubricant. Using a quality gun cleaner and a brush, such as a toothbrush or nylon cleaning brush will work. Following the cleaning process, carefully lubricate the trigger components with a high-quality gun oil or grease. Proper lubrication reduces friction and ensures smooth operation.
Problem Solving
When troubleshooting any trigger issues, start with the simple solutions. If your trigger feels gritty, try cleaning and lubricating the components. If the trigger pull is heavy, and your model is designed to have a heavier pull, explore lighter spring options. If malfunctions persist, it is best to seek help from a professional.
Safety First
Safety should always be your top priority. Always treat every firearm as if it were loaded. Never point your firearm at anything you are not willing to destroy. During dry firing exercises, always ensure the firearm is unloaded, and that there is no ammunition in the area. If you are experiencing an issue you are unfamiliar with, seek help from a qualified gunsmith. Proper storage is critical. When not in use, keep the M&P, unloaded, in a secure location, inaccessible to unauthorized individuals.
Aftermarket Trigger Upgrades and Modifications
Upgrade Options
For those seeking to further refine their M&P trigger, the aftermarket offers a wide array of upgrade options. Choosing the right components can greatly improve the shooting experience.
Several types of aftermarket triggers are available. Trigger shoes are replacements for the part of the trigger you interact with. They come in various shapes, including flat-faced and curved options, each offering a different feel and potential ergonomic advantages. Trigger bars and complete trigger kits replace major trigger components. These kits often include the trigger shoe, trigger bar, springs, and other parts designed to optimize performance.
Benefits of Upgrading
The benefits of aftermarket upgrades are numerous. Reduced trigger pull weight is one of the most sought-after improvements. A lighter trigger pull can contribute to greater accuracy and trigger control. A shorter reset allows for faster follow-up shots, improving your overall rate of fire. Most aftermarket kits include trigger shoes, trigger bars, and springs for smoother and more consistent pulls.
Making the Right Choice
When choosing aftermarket parts, consider your shooting style and needs. Are you looking for a competition-ready trigger? Or do you prioritize reliability and a comfortable feel for everyday carry? Research reputable brands that are made of quality materials. Take your time and do your research before making a purchase. If you aren’t comfortable with the installation, seek professional assistance.
Conclusion
The M&P trigger is an integral part of a high-performing pistol. By understanding the trigger system, identifying potential issues, and implementing proper maintenance practices, you can ensure your M&P is reliable and accurate. Regular maintenance is the key to long-term operation, while aftermarket modifications allow you to further tailor the trigger to your specific shooting preferences.
Remember, a well-tuned trigger contributes directly to accuracy and control. Whether you choose to stick with the factory trigger, or upgrade to an aftermarket kit, the most important thing is to familiarize yourself with how the trigger works and ensure it functions reliably.
