Introduction
The Glock 19. A name synonymous with reliability, simplicity, and a prominent position in the world of firearms. Its popularity stems from its easy handling, straightforward design, and consistent performance. Many gun owners, both seasoned professionals and enthusiastic newcomers, choose the Glock 19 for its versatility. However, even a firearm as widely praised as the Glock 19 can be improved. One common upgrade that significantly enhances the shooting experience is a Glock 19 trigger replacement. This article provides a comprehensive guide, detailing the process step-by-step, ensuring you can confidently tackle this upgrade and enjoy a more refined and accurate shooting experience.
One of the primary reasons gun owners consider a Glock 19 trigger replacement is the potential for improvement. The stock trigger, while functional, often has a slightly heavier pull weight and a longer travel distance than what many shooters prefer. This can lead to a less precise feel and potentially impact accuracy, particularly at longer distances. A well-chosen aftermarket trigger can significantly reduce the pull weight, creating a smoother and more crisp break. This, in turn, allows for more consistent shot placement and enhances overall confidence.
Beyond the practical benefits, a Glock 19 trigger replacement can also improve the overall handling and enjoyment of your firearm. A lighter and more responsive trigger can make the Glock 19 feel more intuitive and responsive, especially during rapid fire drills or competitive shooting scenarios. The improved feel can also translate to a more pleasurable shooting experience overall, encouraging you to spend more time at the range and further hone your skills. Furthermore, replacing your trigger gives you the opportunity to personalize your Glock, creating a firearm that is truly tailored to your preferences.
Safety First: Before You Begin
Before embarking on this project, thorough preparation is essential for a successful and safe outcome. It is paramount to prioritize safety above all else. This involves making absolutely certain that the firearm is unloaded before beginning any work. Double-check. Triple-check. The importance of this step cannot be overstated. It’s a fundamental rule.
First, you must ensure your firearm is completely unloaded. Remove the magazine. Physically inspect the chamber to confirm there is no ammunition present. Point the muzzle in a safe direction at all times, away from any people or objects. Verify that the slide is locked to the rear.
Gathering Your Tools and Parts
Next, gather all the necessary tools and parts. A clean and organized workspace is a crucial element for performing the operation correctly. The process will require a specific set of items to be gathered for ease of use.
- Punches and Hammer: You’ll need a set of punches. Gunsmithing punches are often a good choice, but standard roll pin punches work well too. The size of the punch will depend on the pins. A small gunsmithing hammer or a similar lightweight hammer is also essential. Avoid using overly large or heavy hammers to prevent damage.
- Armorer’s Tool: While not strictly essential, an armorer’s tool or a Glock-specific tool is highly recommended. This tool is often a multi-purpose device, including a punch and a tool for disassembling the slide and frame.
- New Trigger Assembly/Trigger Components: This is the core of the project. Choose your replacement components carefully. Research various options, considering factors such as trigger pull weight, break characteristics, and overall feel. Ensure the components are compatible with your generation of Glock 19.
- Lubricant: A small amount of quality gun oil is useful. This is used for lubricating the internal components.
- Cleaning Supplies (Optional, but Recommended): It’s a good idea to have some gun cleaning solvent or cleaner and a brush or patches on hand to clean parts if needed.
- Soft Surface: Use a gun cleaning mat or a soft, clean surface to prevent scratching the slide or frame.
Prepare your workspace by ensuring adequate lighting and organization. A well-lit area allows for precise manipulation of the small parts. A clean work area reduces the risk of losing components. Keep everything neat and tidy to easily keep track of parts and the steps you’ve completed. Having everything laid out properly allows for a quick operation.
Disassembling the Glock 19 Slide
The Glock 19 trigger replacement process begins with disassembly of the slide.
Before anything else, the slide must be removed from the frame. Once you are certain the firearm is unloaded, begin by pulling the slide to the rear. Engage the slide lock lever to hold the slide in the open position. Then, while pressing down on the two takedown tabs on either side of the frame, gently slide the slide forward off the frame.
Once the slide is off the frame, the process to remove the internal components from the slide can begin. This is a straightforward procedure. Start by removing the guide rod and spring assembly. It simply slides out.
Next, remove the firing pin assembly. This often involves depressing the firing pin safety plunger at the rear of the slide. This allows you to slide the firing pin assembly out. Be careful, as the firing pin spring is under tension.
With the firing pin assembly out, remove the extractor and the extractor depressor plunger. These components are located on the right side of the slide. The bearing is located underneath the extractor, so keep an eye out for it so you don’t lose it.
These steps will allow access to the components necessary for the next phase of the process, the trigger replacement.
Disassembling the Glock 19 Frame
Once the slide internals are removed and the slide is set aside, we move on to disassembling the Glock 19 frame.
To begin, remove the trigger pin. Using your punch, push the pin through the frame. A roll pin punch set can make this easier. Gently tap the punch with your hammer. Be careful not to damage the frame. Work slowly and carefully.
Now, you need to remove the trigger mechanism housing. This housing contains the trigger bar, connector, and firing pin safety mechanism. Once the trigger pin is removed, this assembly should slide out.
Next, remove the slide stop lever and the lock spring. The slide stop lever has a small pin. Once you’ve removed the pin, you can slide it out of the frame. Be mindful of its orientation for reassembly.
The ejector is typically part of the trigger mechanism housing, but in some Glock 19 generations, it’s a separate component. Remove the ejector if necessary.
Installing the New Trigger
With the frame now disassembled, the old trigger and trigger mechanism can be replaced with the new components.
Now for the exciting part: installing your brand new trigger.
Installation is largely the reverse of the disassembly process. Carefully place the new trigger assembly and trigger components into the frame. The orientation and placement of these parts are essential for proper function.
Insert the trigger mechanism housing. It needs to align correctly with the holes in the frame. Ensure everything is seated properly.
Once the trigger mechanism housing is in place, reinsert the trigger pin. Use the punch to align and drive the pin home.
Now reinsert the slide stop lever and the lock spring, again, ensuring they’re correctly oriented.
If you had removed the ejector, reinstall it now, making sure it is securely seated in its slot.
After reassembling the frame, reinstall all the slide internals, ensuring they are seated correctly.
This is an important step, double-check all components to make sure they are oriented and installed correctly.
Function Checks and Test Firing
With the new trigger installed and the frame reassembled, it’s time to perform a series of crucial function checks. These tests verify the trigger’s proper operation.
First, test the trigger pull. Does it have the desired weight and feel? Is the break crisp and clean? Does the trigger reset correctly?
Then, test the safety mechanisms. Ensure that the trigger safety (the small lever within the trigger) functions correctly, preventing the trigger from firing unless depressed. Test the firing pin safety, which blocks the firing pin from moving forward unless the trigger is pulled.
Finally, cycle the slide. Rack the slide repeatedly to ensure smooth operation and proper feeding and ejection. Confirm that the slide locks back on an empty magazine.
Following the functional checks, a live-fire test is highly recommended. If you are comfortable, take your newly enhanced Glock 19 to a shooting range in a safe and controlled environment.
Start by dry-firing the weapon at the range to familiarize yourself with the new trigger. Then, when ready, load your Glock 19 and carefully test fire it.
If you encounter any malfunctions or experience any issues, immediately cease firing and carefully re-examine your installation. It is recommended to recheck all steps in the process.
Trigger Replacement Options
Many aftermarket trigger kits and upgrades exist. Options are available to tailor your Glock 19’s trigger to your exact preferences.
There are several different trigger options available, ranging from complete trigger assemblies to individual components.
Aftermarket triggers are a popular upgrade. These triggers are designed to provide a smoother pull and a more consistent break. They are usually made from high-quality materials and are available in a variety of designs and finishes.
Connectors are another common upgrade. These small components are responsible for releasing the firing pin. Replacing the connector can often reduce trigger pull weight and improve the overall trigger feel.
Trigger springs can be replaced with lighter-weight or modified springs. While these will affect pull weight, they also need to be installed safely.
Trigger shoes, a portion of the trigger itself, can also be changed to change the overall feel of the trigger.
No matter what you choose to install, it’s a good idea to consult resources to provide information and guidance.
