Understanding the Glock Trigger and Trigger Bar
The Trigger System Explained
The Glock trigger system, although simple in design, is a marvel of engineering. It’s based on a principle of mechanical interaction. When you pull the trigger, it engages a series of interconnected parts. First, the trigger itself pulls the trigger bar rearward. The trigger bar then interacts with the connector, a small, angled piece located within the frame. The connector eventually releases the firing pin, striking the primer of the cartridge and initiating the firing process.
The Role of the Trigger Bar
The Glock trigger bar plays a pivotal role in this chain of events. It is a flat, metal piece that travels the length of the frame. Its primary job is to move rearward when the trigger is pulled, ultimately interacting with the connector and firing pin safety plunger. The surface of the trigger bar interacts with a few key components. During trigger pull, the trigger bar’s engagement with the connector is critical for a clean break, as it’s the point where the firing pin is released. Any friction at this point can translate into a rough trigger pull.
Areas for Polishing
Polishing the trigger bar focuses on smoothing the surfaces that make contact with other parts of the trigger mechanism. This process reduces friction and creates a more refined feel. You may find that areas that require polishing are the ones where the trigger bar contacts the connector or the cruciform. While doing this procedure, it is important to carefully inspect each component before reassembly and note how they interact.
Materials and Tools Needed
Preparation is Key
Before beginning any work on your Glock, ensure you have all the necessary tools and materials. This preparation will make the process smoother and more efficient. Here’s a list of what you’ll need:
- Your Glock pistol (ensure it’s unloaded and cleared.)
- Trigger pin removal tool. This specialized tool is necessary to push out the pins that hold the trigger mechanism in place.
- A punch set. Various sized punches will be useful.
- A small flathead screwdriver
- A soft mallet (optional) This can be helpful for gentle taps during disassembly and reassembly.
- Polishing compound. Several compounds work very well for this, some examples are polishing paste, or metal polishes like those produced by Flitz or Mother’s Mag & Aluminum Polish.
- Gun cleaning solvent. Something that will remove grime and debris to prepare your pieces.
- Cleaning cloths or rags.
- Cotton swabs or Q-tips. These are ideal for applying polishing compound and cleaning the surfaces being polished.
- Safety glasses. Protection for your eyes is paramount.
- Gloves. To protect your hands and provide a better grip on small parts.
Safety First
It is of utmost importance to emphasize safety. Always work in a well-lit, organized area. Ensure your work surface is clean and free of clutter. Before beginning any disassembly, always verify that the firearm is unloaded. Remove the magazine, clear the chamber, and visually inspect it to ensure it is empty. Double-check it. Treat every firearm as if it is loaded.

Safety First, Again
Polishing your Glock trigger bar requires patience and care. Rushing the process can lead to unintended consequences, such as damaging parts or altering the function of the firearm. Work deliberately and methodically.
Safety is the most critical aspect of this process, repeated here for emphasis. Ensure the firearm is completely unloaded. Remove the magazine. Clear the chamber. Double-check that the chamber is empty. Keep the muzzle pointed in a safe direction.
Disassembly Steps
Now, proceed with the following steps for disassembly:
- Field Strip the pistol. Following Glock’s instructions, start by removing the slide. Point the muzzle down. Then, pull the slide back slightly while pulling down on the takedown levers. The slide should now move forward and off the frame.
- Remove the slide components. Pull the barrel, recoil spring assembly, and firing pin assembly from the slide.
- Disassemble the frame. Use a punch and the trigger pin removal tool to push out the trigger pin and locking block pin.
- Remove the trigger mechanism. Carefully remove the trigger, trigger bar, and connector.
- Inspect the parts. Lay out the trigger components.
Cleaning the Components
The next step involves cleaning the trigger bar. Use gun cleaning solvent to thoroughly clean the trigger bar, especially the areas that make contact with other components. Remove any existing grease, oil, or debris. Then, dry the trigger bar with a clean cloth.
Polishing Procedure
Now, onto the actual polishing:
- Apply a small amount of polishing compound to a cotton swab or a clean cloth. Don’t overdo it; a little goes a long way.
- Carefully apply the polishing compound to the areas of the trigger bar that interact with the connector, and the cruciform. These are the primary contact points where friction occurs.
- Using gentle, circular motions, polish the surfaces. Apply moderate pressure. Don’t apply excessive pressure, as you don’t want to remove too much material.
- Continue polishing for several minutes, checking your progress frequently.
- Take your time. Polishing requires a patient touch.
Final Cleaning and Inspection
After polishing, remove all remaining polishing compound from the trigger bar. Use a clean cloth or cotton swab dipped in gun cleaning solvent. Ensure no residue remains. Inspect the trigger bar for any imperfections or signs of uneven polishing. If any remain, address them.
Reassembly Instructions
Now, reassemble the firearm. Reassembly is the reverse of disassembly.
- Reassemble the frame. Carefully reinsert the trigger mechanism, trigger bar, and connector back into the frame. Replace the trigger pin and locking block pin.
- Replace the slide and reassemble the slide.
- Function test the firearm.
Testing and Troubleshooting
Function Testing Protocol
Once you’ve reassembled your Glock, it’s time to perform a thorough function test.
- Dry-fire the firearm. Ensure the trigger pulls smoothly and consistently.
- Check the trigger reset. Make sure the trigger resets fully and reliably.
- Cycle the slide. Verify that the slide cycles correctly and that the trigger resets after each cycle.
Addressing Potential Issues
If you encounter any issues, don’t panic. Troubleshooting is a part of the process. Here are some common problems and potential solutions:
- The trigger does not reset. This is a common issue. If this occurs, it is likely due to some interference. Re-examine the trigger bar and connector. Inspect for any burrs, obstructions, or misalignment. Also, inspect the connector for any bends or damage.
- The trigger pull is still rough or gritty. If this occurs, go back and re-polish. Use finer grit polishing compound and/or spend more time on the polishing process. You may also have missed contact points that require polishing.
- The trigger feels lighter than before. This is a potential benefit. If it feels lighter, this means the friction has been reduced. If this is the case, be extra sure to test the safety of the firearm.
