Understanding the Glock 19 Gen 5 Trigger System
The Fundamentals
The crisp snap of a well-tuned trigger. The seamless transition from thought to action. For many gun owners, the trigger is the vital link between intent and execution. The Glock 19 Gen 5, a cornerstone of the concealed carry and duty pistol world, has earned a reputation for reliability and ease of use. But for some, the factory trigger can feel a little… lackluster. It might have a long pull, a slightly mushy feel, and a pull weight that, while safe, isn’t always optimized for speed and precision. But the good news is, there’s a whole world of aftermarket parts designed to elevate your Glock 19 Gen 5’s performance.
This article will delve into the realm of Glock 19 Gen 5 trigger upgrades, exploring the common shortcomings of the factory trigger, explaining how the trigger system functions, and offering a comprehensive guide to improving accuracy, speed, and overall shooting enjoyment. We’ll cover different types of upgrades, the factors to consider when making your choices, and provide you with recommendations to get you started on the path to a better shooting experience.
Key Components
At its core, the Glock 19 Gen 5 trigger system is a marvel of engineering, a testament to its simplicity and effectiveness. It’s a striker-fired system, meaning a spring-loaded firing pin, or striker, is what strikes the primer and ignites the cartridge. Understanding the basic components is key to appreciating how the upgrades work.
The process begins when you pull the trigger. The trigger bar, a long, curved piece of metal, engages with the connector, a small, angled piece that controls the sear engagement. This interaction pulls the trigger bar rearward, eventually releasing the striker. Simultaneously, the trigger spring and the firing pin safety (FPS) are compressed. The combined effect is a controlled release of the striker, striking the primer and firing the round. The trigger also controls the all-important firing pin safety, designed to prevent the gun from firing if dropped or subjected to significant impact.
Key components to focus on include the trigger bar itself, the connector, the trigger spring, the striker spring, and the firing pin safety. The interaction of these parts dictates the pull weight, the travel distance of the trigger, and the all-important reset. Reset refers to the point at which the trigger springs forward and is ready to fire the next round, an important consideration for rapid fire and follow-up shots. Gen 5 specifically, introduced design changes aimed at improved durability, reliability and a smoother action, building on the foundation of earlier generations. The trigger bar’s design was modified, improving the overall feel.
Why Consider Upgrading Your Glock 19 Gen 5 Trigger?
Enhanced Performance
The motivation to upgrade a Glock 19 Gen 5 trigger often comes from a desire to improve the shooting experience and unlock a pistol’s full potential. There are several significant advantages to be gained.
One primary benefit is a marked improvement in accuracy. A lighter and crisper trigger pull minimizes the disruption of the muzzle when the shot is fired. The subtle movement of the firearm, often caused by the shooter’s natural tendency to torque the gun while squeezing the trigger, is reduced when the trigger is tuned. This contributes significantly to tighter groupings and more precise shot placement. When your shots consistently land where you intend, confidence soars.
Faster Split Times
Another critical benefit is a faster split time, the time between shots. A shorter, more positive reset (the point at which the trigger springs forward after firing) enables faster follow-up shots. This is a crucial advantage for both defensive scenarios, where speed is paramount, and in competitive shooting, where fractions of a second can determine the winner. The quicker the reset, the faster you can bring your sights back on target and engage the next shot.
Improved Feel and Comfort
Beyond performance, an upgraded trigger often brings a welcome improvement to the feel and comfort of shooting. A smoother and more predictable trigger pull, free from grittiness or creep, makes the entire shooting experience more enjoyable. Less effort is required to manipulate the trigger, resulting in reduced fatigue, especially during extended range sessions. A well-tuned trigger just feels better.
Exploring Different Types of Glock 19 Gen 5 Trigger Upgrades
Complete Trigger Assemblies
The aftermarket for Glock triggers is vast, offering a wide array of options. Here’s a look at the most common upgrades:
Choosing a complete trigger assembly is often the most comprehensive approach. These kits include the trigger, trigger bar, connector, and sometimes even the trigger spring. They offer a drop-in solution for a lighter and smoother trigger pull. You’ll find reputable brands like Apex Tactical, Zev Technologies, and Johnny Glocks offering quality kits. These assemblies are generally considered safe and reliable, providing an overall package designed to improve trigger performance while simplifying the upgrade process. Benefits include a significant reduction in trigger pull weight, a shorter reset, and a smoother overall feel.
Trigger Connectors
Connectors are the unsung heroes of the trigger system, impacting pull weight and feel. They’re the small, angled pieces that control the sear engagement. Different connectors offer different pull weights. For example, a factory connector often yields a heavier pull, while a lighter connector offers a lighter pull weight. Aftermarket options are often more polished and precisely manufactured than the original parts. Brands such as Ghost Inc. and Zev Technologies offer various connector options.
Trigger Springs
Trigger springs, and their partner the firing pin spring, play a crucial role in the overall trigger pull weight and reset characteristics. A lighter trigger spring can reduce the pull weight. Replacing the firing pin spring can also contribute to a better feel. However, be extremely cautious. Going too light can increase the risk of light primer strikes, where the primer doesn’t ignite the cartridge.
Trigger Shoes
Trigger shoes or trigger faces change the surface and feel of the trigger itself. These upgrades are not just cosmetic. They change the curvature of the trigger face. Flat-faced triggers are popular as they enable a more consistent trigger pull. They are usually made of aluminum or other strong materials, providing better feel and durability. This is often the easiest and most affordable upgrade, as it simply replaces the trigger face with a new one.
Key Considerations When Choosing a Trigger Upgrade
Purpose and Skill Level
Selecting the right Glock 19 Gen 5 trigger upgrade requires careful consideration of your individual needs and priorities.
First, think about your intended use. If you’re primarily using your Glock for self-defense or concealed carry, prioritize reliability. A lighter trigger might be desirable, but ensure it is still safe and reliable in a high-stress situation. For competition shooting, you might seek a lighter trigger pull and a faster reset for a competitive edge. For recreational shooting, focus on the overall feel and enjoyability.
Second, consider your experience level. If you are new to firearms, a heavier trigger pull can be a good way to learn proper trigger control, which reduces the potential for accidental discharge. A lighter trigger can be advantageous for more experienced shooters, who know how to maintain control.
Reliability, Safety, and Regulations
Third, pay careful attention to reliability. Choose products from reputable brands that have a proven track record. Read reviews and do your research. This is not the time to cut corners. The trigger is a critical part of your firearm.
Fourth, safety should always be your top priority. If you’re not comfortable performing the installation yourself, seek professional assistance. Always perform a safety check after any trigger work. A proper safety check includes a function check and, if you choose to adjust pull weight, always be aware of potential liability.
Fifth, familiarize yourself with the trigger pull weight. There are several ways to measure this, including using a trigger pull gauge. Determine what is the right pull weight for your use and for you.
Finally, be aware of any local regulations regarding trigger modifications. Ensure that any changes you make are compliant with local laws.
