Tools Required:
- Punch: A small, appropriately sized punch (brass is preferred to avoid damaging parts).
- Small flathead screwdriver: For aiding in the removal of the trigger bar.
- Clean workspace: A clean, well-lit area is crucial for safe and efficient work.
- Appropriate safety equipment: Eye protection is mandatory.
Step-by-Step Disassembly:
1. Safety First: Ensure the firearm is unloaded and the magazine is removed. Visually inspect the chamber to confirm it is empty. Point the firearm in a safe direction throughout the entire process.
2. Removing the Trigger Housing Pin: Using your punch, carefully drive out the trigger housing pin located at the rear of the trigger housing. This pin secures the trigger housing to the frame. Gently tap, avoiding excessive force.
3. Separating the Trigger Housing: Once the pin is removed, the trigger housing will separate from the frame.
4. Disconnecting the Trigger Bar: The trigger bar is connected to the trigger and the sear. Gently pry up on the front end of the trigger bar, using the small flathead screwdriver if necessary. Note the orientation of the trigger bar for reassembly.
5. Removing the Trigger: The trigger can now be carefully removed from the trigger housing.
6. Removing the Sear: The sear is located near the trigger. It's usually held in place by a small spring. Gently lift it out.
7. Removing the Connector: This is a small component located between the trigger bar and the sear. Remove it carefully.
8. Inspecting Components: Inspect each component for wear, damage, or any signs of excessive use. Replace any damaged or worn parts.
Step-by-Step Reassembly:
1. Reinstalling the Connector: Reinstall the connector, making sure it is properly seated.
2. Reinstalling the Sear: Gently install the sear back into its proper location. Ensure the spring is properly seated.
3. Reinstalling the Trigger: Carefully place the trigger back into the trigger housing. Ensure it aligns correctly.
4. Reinstalling the Trigger Bar: Replace the trigger bar, making sure the orientation is the same as it was during disassembly.
5. Reinstalling the Trigger Housing: Align the trigger housing with the frame and carefully insert the trigger housing pin.
6. Tapping the Trigger Housing Pin: Gently tap the trigger housing pin back into place. Avoid excessive force.
7. Final Inspection: Inspect the assembly, ensuring all components are properly seated and the FCG functions smoothly.
8. Test Fire (With Caution): Once reassembled, test fire the weapon at a safe shooting range to verify functionality. Always follow safe gun handling procedures.
Important Considerations:
- Spring Tension: Be mindful of the spring tension during disassembly and reassembly. Lost springs can cause malfunctions.
- Orientation: Pay close attention to the orientation of all components. Improper assembly can lead to malfunction or damage.
- Professional Help: If you are not comfortable performing this procedure, seek help from a qualified gunsmith. This guide is for educational purposes only. Improper handling of firearms can be dangerous.
This detailed guide provides a thorough understanding of the Glock 19 FCG disassembly and reassembly process. Remember safety is paramount; always prioritize responsible firearm handling.
