5 Common Glock 19 Gen 5 Problems
1. Ejection Issues
The Glock 19 Gen 5 is generally known for its reliable performance and minimal ejection issues. However, if you’re experiencing feeding problems with your Glock 19 Gen 5, here are a few steps you can take to troubleshoot and potentially fix the issue:
Clean and lubricate the firearm: Make sure your Glock 19 Gen 5 is clean and properly lubricated. Accumulated dirt, debris, or lack of lubrication can affect the ejection process. Clean the barrel, slide, extractor, and other relevant parts following Glock’s recommended cleaning procedures.
Inspect the extractor: The extractor is responsible for gripping the spent casing and jamming it from the firearm. Ensure that the extractor is clean and free of debris or obstructions. Check for any damage or wear on the extractor itself. If necessary, consider replacing the extractor.
Check the ejector: The ejector is another crucial component involved in ejection. Verify that it is properly installed, aligned, and not damaged. If the ejector appears worn or damaged, it may need to be replaced.
Ammunition selection: Inconsistent ejection issues can sometimes be related to the ammunition being used. Try different brands or types of ammunition to see if the problem persists. Some ammunition may have variations in power or quality that can affect ejection.
Grip and stance: Ensure that you have a firm and consistent grip on the firearm, and maintain a stable shooting stance. A loose grip or improper technique can potentially affect ejection reliability.
Seek professional assistance: If the above steps do not resolve the ejection issues, it is recommended to seek the help of a qualified gunsmith or Glock-certified armorer. They will have the expertise to diagnose and fix any specific problems with your Glock 19 Gen 5.
2. MOS Issues
The Glock 19 Gen 5 MOS (Modular Optic System) variant allows for the mounting of various optics on the slide. If you’re experiencing issues with your Glock 19 Gen 5 MOS, specifically related to the optic system, here are some common problems and potential solutions:
Optic mounting: Ensure that the optic is properly mounted and securely attached to the slide. Check that the mounting screws are tightened to the manufacturer’s recommended torque specifications. If the optic is loose or shifting during use, tighten the screws accordingly.
Optic compatibility: Verify that the optic you are using is compatible with the Glock MOS system. Some optics may require specific mounting plates or adapters for proper fitment. Refer to the Glock MOS instructions or contact the optic manufacturer for compatibility information.
Sight alignment: If the optic is properly mounted but the sight picture is off or inconsistent, check for correct sight alignment. Some optics may require adjustments to windage and elevation to zero in on the target. Refer to the optic’s manual or contact the manufacturer for guidance on sight alignment and adjustment.
Battery and connections: For optics with electronic components, ensure that the batteries are properly installed and have sufficient charge. Check the battery contacts for cleanliness and make sure they are making proper contact. If the optic has any cables or connections, ensure they are securely connected and not damaged.
Recoil management: Mounting an optic on the slide can sometimes introduce additional recoil forces, which may impact the optic’s performance. If you experience issues such as the optic losing zero or becoming misaligned, consider using stronger recoil springs or seeking professional advice from a gunsmith familiar with Glock MOS systems.
Seek professional assistance: If the above steps do not resolve the issues with your Glock 19 Gen 5 MOS, it is recommended to consult with a qualified gunsmith or reach out to Glock’s customer support. They will have the expertise to diagnose and address any specific problems related to the MOS system.
3. Trigger Issues
If you’re experiencing trigger issues with your Glock 19 Gen 5, where the trigger is not functioning properly or exhibiting any inconsistencies, here are some steps you can take to troubleshoot and potentially resolve the problem:
Clean and lubricate the trigger assembly: Ensure that your Glock 19 Gen 5’s trigger assembly is clean and properly lubricated. Use an appropriate cleaning solvent to remove any dirt, debris, or excess oil from the trigger components. Apply a light coat of lubrication to the recommended areas of the trigger assembly.
Inspect the trigger bar and connector: Check the trigger bar and connector for any signs of damage, wear, or debris accumulation. Clean these parts thoroughly and ensure they are properly aligned. If there are any damaged or worn-out components, consider replacing them with genuine Glock parts.
Check for obstructions or foreign objects: Inspect the trigger housing and other areas around the trigger for any obstructions or foreign objects that may be interfering with the trigger’s movement. Remove any debris or foreign objects carefully.
Verify proper installation and fitment: Double-check that all trigger components are installed correctly and seated properly. Ensure that the trigger spring is correctly aligned and providing the necessary tension.
Review your grip and finger placement: Ensure that you have a consistent and proper grip on the firearm. Improper finger placement on the trigger or a weak grip can cause trigger issues. Practice proper shooting techniques and experiment with your grip to find a comfortable and reliable trigger pull.
Seek professional assistance: If the trigger issues persist or if you are uncomfortable working on your firearm, it is recommended to seek the help of a qualified gunsmith or Glock-certified armorer. They will have the expertise to diagnose and fix any specific problems with your Glock 19 Gen 5 trigger.
4. Barrel Issues
If you’re experiencing issues with the barrel of your Glock 19 Gen 5, such as accuracy problems or malfunctions, here are some steps you can take to troubleshoot and potentially fix the issue:
Clean the barrel: Ensure that the barrel is clean and free from any debris, fouling, or obstructions. Use an appropriate cleaning solvent and a bore brush to clean the barrel thoroughly. Pay special attention to the chamber area and the crown (the end of the barrel).
Inspect the barrel: Check the barrel for any signs of damage, such as bulges, cracks, or excessive wear. If you notice any abnormalities, it may be necessary to replace the barrel. Additionally, inspect the feed ramp for any burrs or rough spots that may cause feeding issues.
Check the barrel crown: The crown, located at the muzzle end of the barrel, plays a crucial role in maintaining accuracy. Ensure that the crown is clean and free from any damage or irregularities. A damaged or improperly aligned crown can negatively impact accuracy. If necessary, consult a gunsmith for barrel crown inspection or repair.
Ammunition selection: Inconsistent or unreliable performance may sometimes be related to the ammunition being used. Ensure that you are using high-quality, factory-manufactured ammunition that is appropriate for your Glock 19 Gen 5. Consider trying different brands or types of ammunition to see if the problem persists.
Seek professional assistance: If the issues with your Glock 19 Gen 5 barrel persist or if you’re unsure about any aspect of troubleshooting, it is recommended to seek the help of a qualified gunsmith or reach out to Glock’s customer support. They will have the expertise to diagnose and address any specific problems with the barrel or related components.
