Understanding the Factory Trigger’s Limitations
Long Pull Distance
One of the first things many shooters notice is the relatively long pull distance. This means the trigger must travel a significant distance before the pistol fires. A long pull distance can make it harder to maintain a consistent trigger press, increasing the likelihood of pushing the gun off target, particularly during rapid fire. It also can make it feel less responsive.
Heavy Pull Weight
Another concern is the factory trigger’s pull weight. Many shooters find the stock Shield trigger heavier than they prefer. A heavier trigger pull can fatigue the shooter’s trigger finger, leading to inconsistent shots and potential accuracy issues. A heavier pull can also slow down follow-up shots.
Mushy or Gritty Feel
The feel of the trigger pull is another area for improvement. Many describe the factory trigger as “mushy” or “gritty.” This lack of crispness makes it challenging to predict when the trigger will break (the moment the gun fires). This unpredictability can contribute to poor accuracy and a less enjoyable shooting experience.
Long Reset
Finally, the reset, the distance the trigger travels forward after the shot before it’s ready to fire again, can also be somewhat long on the stock Shield trigger. A long reset time means a longer delay between shots, impacting split times and hindering the ability to take fast, accurate follow-up shots.
These factors combined can create a trigger that, while safe and functional, doesn’t allow the shooter to reach their full potential. Addressing these issues through an upgrade can significantly enhance the shooting experience.
The Advantages of a Trigger Enhancement
The advantages of a well-executed trigger upgrade are numerous. First and foremost, a better trigger can improve accuracy. A shorter pull, a lighter pull weight, and a crisper break will allow for more precise shot placement. The shooter can press the trigger more consistently, reducing the likelihood of pulling the shot.
Second, a trigger upgrade can dramatically improve the speed of follow-up shots. A shorter reset allows the shooter to quickly re-acquire the trigger and prepare for the next shot. This is particularly important in defensive situations, where speed and accuracy are paramount.
Furthermore, a trigger upgrade often enhances the overall shooting experience. A better-feeling trigger is simply more enjoyable to use. It can reduce fatigue, build confidence, and allow the shooter to focus on other aspects of their shooting technique. A clean, crisp trigger makes shooting more intuitive and fun.
Exploring Popular Trigger Upgrade Options
Aftermarket Trigger Shoes
One popular upgrade involves replacing the factory trigger shoe with an aftermarket version. These replacement triggers often feature a different shape, such as a flat-faced design, which allows for a more consistent and ergonomic finger placement. This can improve trigger feel and even help with pulling the trigger straight back.
A flat-faced trigger can also reduce pre-travel, the distance the trigger moves before it engages the sear. A shorter pre-travel translates to less movement needed before the gun fires. These triggers come in a variety of materials and finishes, allowing you to customize your pistol’s appearance as well as its function. Brands such as Apex Tactical and Overwatch Precision are well-regarded in this category.
Trigger Kits (Trigger, Sear, Spring Upgrades)
Another common upgrade involves complete trigger kits that replace several components of the stock trigger assembly. These kits usually include an upgraded trigger, along with parts such as a sear, a trigger return spring, and sometimes a striker spring. The combined effect of these upgrades can significantly improve the trigger pull.
The upgraded trigger itself might have a different shape or geometry, enhancing the feel. The sear is often redesigned for a crisper break and reduced travel. The trigger return spring and/or striker spring typically have a lighter weight, which lowers the trigger pull weight.
These comprehensive kits offer a holistic approach to trigger improvement. They are often easy to install and provide a substantial improvement in performance. Several companies specialize in these trigger kits. Apex Tactical, for instance, offers its “Forward Set Sear & Trigger Kit” to provide an improved feel, and Galloway Precision is also known for its quality kits.
Trigger Springs
Another option is to replace just the trigger springs to try and get a lighter trigger pull. Lighter trigger return springs can reduce pull weight, making the trigger feel smoother and less heavy. The benefit of using lighter trigger springs is an inexpensive upgrade that can often improve the trigger pull.
However, it’s crucial to consider potential downsides. Using lighter springs *can* impact reliability. Make sure to test the pistol thoroughly after installing lighter springs to ensure consistent primer ignition, especially if the gun is going to be used for carry. Also, you should test the gun after any trigger upgrade to ensure it is still safe and reliable, as well as to make sure it is functioning properly.
Selecting the Right Upgrade for You
Choosing the optimal trigger upgrade requires careful consideration of several factors. The ideal upgrade is the one that best suits your individual needs and preferences.
One key consideration is your shooting style. Do you primarily shoot at the range, or is this a carry gun? Competition shooters may prefer a very light and crisp trigger, while a carry gun requires a trigger that’s smooth and reliable.
Consider the intended use of your Shield. A carry gun’s trigger should prioritize safety and reliability. If it will be used for self-defense, you must balance improved performance with utmost dependability. For range shooting or competition, you can often prioritize a lighter pull weight and a shorter reset.
Your budget is another key factor. Trigger upgrades range in price from affordable trigger shoes to more expensive complete kits. You must balance the cost of the upgrade with your desired performance improvements.
Ease of installation is also important. Some upgrades are simple drop-in replacements, while others require more involved modifications. If you are not comfortable with gunsmithing, choose an upgrade that is relatively easy to install or consider having a qualified gunsmith perform the work.
When selecting an upgrade, it helps to compare and contrast different brands and models. Research the features, benefits, and drawbacks of each option. Read reviews from other users. Consider the reputation of the manufacturer and the quality of their products.
Look for reviews from other M And P Shield 9mm owners to find out what they’ve tried and what they like or dislike. Focus on the features that are most important to you, such as pull weight reduction, trigger break, and reset.
Navigating the Installation Process
While many trigger upgrades are designed for easy installation, you must follow a few steps. A general overview will help you understand what to expect.
Carefully read and follow the manufacturer’s instructions. Gather the necessary tools, such as a punch set and a small hammer. Watch installation videos, as these are often a great help. Be sure to work in a well-lit area and keep your workspace organized.
Safety is paramount. Always ensure the firearm is unloaded before disassembling it. Double-check that the chamber is empty. Work methodically, taking care not to damage any components. If you feel uncomfortable or unsure at any point, consult a qualified gunsmith.
Evaluating Performance After the Upgrade
After installing your trigger upgrade, it’s crucial to evaluate its performance. Start with dry firing to get a feel for the new trigger pull. Pay attention to the pull weight, the trigger break, and the reset.
Then, proceed to live firing. Focus on how the trigger feels and how it impacts your accuracy and split times. Does the new trigger allow for better shot placement? Does it allow for faster follow-up shots?
If you experience any issues, such as light primer strikes or failure to reset, troubleshoot the problem immediately. It may be necessary to adjust the components or reinstall the upgrade. Consult the manufacturer’s documentation or seek assistance from a qualified gunsmith.
Maintenance for Lasting Performance
Like any firearm component, your trigger upgrade will require periodic maintenance to ensure optimal performance and longevity. Clean and lubricate the trigger components regularly. Use high-quality gun lubricant to prevent friction and wear.
Inspect the trigger components for wear and tear during cleaning. Replace any damaged parts. If you’re not comfortable with any part of this, seek advice from a qualified gunsmith.
By taking proper care of your trigger upgrade, you can ensure that it continues to provide enhanced performance for years to come.
