This guide provides a comprehensive, step-by-step process for disassembling and reassembling the fire control group (FCG) of a Glock 19 pistol. Always prioritize safety. Before beginning any firearm maintenance, ensure the weapon is unloaded and cleared. Verify this multiple times. Improper handling of firearms can lead to serious injury or death. This guide is for informational purposes only and does not replace professional gunsmithing training.
Tools Required
Before you begin, gather the following tools:
- A properly sized punch: This is crucial for safely removing pins. Avoid using anything that could damage the FCG components.
- A nylon or plastic mallet: Metal hammers can easily mar the finish of your Glock parts.
- A clean, well-lit workspace: This ensures you don't lose any small parts.
- A container or magnetic parts tray: To keep track of all the small components.
Step-by-Step Disassembly
-
Safety Check: Again, confirm the firearm is unloaded and the magazine is removed. Point the muzzle in a safe direction.
-
Remove the Trigger Housing Pin: Using your punch, carefully drive the trigger housing pin out from the right side of the frame. This pin holds the trigger housing in place.
-
Remove the Trigger Housing: Gently separate the trigger housing from the frame. Be mindful of the small spring and components inside.
-
Remove the Connector: Once the trigger housing is removed, you'll see the connector. This is usually held in place by a small pin. Use your punch to carefully remove the connector pin. Remove and set aside the connector.
-
Remove the Trigger Bar: The trigger bar is usually easily removed once the connector is out. Note its orientation for reassembly.
-
Remove the Sear Housing Pin: This pin retains the sear housing assembly. Use the punch to remove the pin carefully, taking care not to damage the surrounding parts.
-
Remove the Sear Spring and Sear: The sear spring and sear will now be free. Carefully remove them, noting their positions.
-
Inspect Parts: Carefully inspect all removed components for wear, damage, or any signs of malfunction.
Step-by-Step Reassembly
Reassembly is essentially the reverse of disassembly. Pay close attention to the orientation of each part and refer to the image(s) below if you have any doubts. Incorrect reassembly can lead to malfunctions and safety issues.
-
Install the Sear and Sear Spring: Carefully install the sear and sear spring into the sear housing.
-
Install the Sear Housing Pin: Insert and tap the sear housing pin back into place.
-
Install the Trigger Bar: Place the trigger bar back into its proper position, aligning it correctly with the trigger mechanism.
-
Install the Connector: Insert the connector pin and then carefully place the connector back into the trigger housing.
-
Install the Trigger Housing: Carefully align the trigger housing with the frame and insert the trigger housing pin from the right side. Tap the pin in until it's securely seated.
-
Safety Check: Perform a thorough function check before loading the firearm. Ensure the trigger functions smoothly and there are no issues.
Important Considerations
-
Professional Help: If you are uncomfortable performing these steps or lack experience, it’s best to seek professional help from a qualified gunsmith.
-
Lubrication: After reassembly, apply a light amount of gun lubricant to the moving parts of the FCG.
-
Cleaning: Regularly clean and lubricate the FCG as part of your routine firearm maintenance.
