Common Concerns Faced by Glock 20 Gen 5 Owners
Despite its reputation for dependability, the Glock 20 Gen 5, like any firearm, can experience problems. Understanding these issues is key to responsible ownership and ensuring optimal performance.
Ejection Challenges
Ejection problems are among the most commonly reported issues with any semiautomatic pistol, and the Glock 20 Gen 5 is no exception. Several different types of ejection issues can occur:
Failure to Extract (FTE)
Failure to Extract (FTE) is a situation where the spent casing remains stubbornly lodged in the chamber, preventing the slide from cycling correctly. This can disrupt the firing sequence and can be quite frustrating during training or a self-defense situation.
Possible Causes: The extractor, the part that grabs the rim of the spent casing, may be worn, broken, or simply not gripping the casing tightly enough. A weak recoil spring, unable to fully cycle the slide, can also contribute to FTEs. Certain ammunition types, particularly those with weaker loads, may not generate sufficient energy to completely cycle the slide.
Potential Solutions: The first step should be to inspect the extractor and its spring. If the extractor is worn, replacing it may resolve the issue. Consider upgrading to a stiffer recoil spring, especially if you frequently shoot high-powered 10mm rounds. Trying different brands or types of ammunition can also help to identify if the problem is ammo-related.
Failure to Eject (FTEj)
Failure to Eject (FTEj) is the opposite of FTE. Here, the spent casing does extract from the chamber but fails to clear the ejection port, often becoming lodged in the slide or causing a jam.
Possible Causes: The ejector, the part that kicks the casing out, might be damaged or worn. A weak ejector spring could fail to impart enough force. A dirty or obstructed chamber can hinder ejection.
Potential Solutions: Inspect the ejector and its associated parts. If the ejector is damaged, replacement will be needed. Ensure the chamber is thoroughly cleaned and free of debris. Try a different brand of ammunition.
Brass to Face (BTF)
Brass to Face (BTF) is a less frequent but irritating issue where the spent casing hits the shooter in the face during ejection. This is usually a symptom of a malfunction with the ejection process.
Possible Causes: This problem often results from the ejector’s angle or an issue with the extractor.
Potential Solutions: Inspection and possible replacement of the ejector and extractor may be necessary. Also, checking the slide for wear or any obstructions.
Recoil Spring Considerations
The recoil spring is crucial for the proper function of a semiautomatic pistol. It absorbs the energy from the fired round and returns the slide to battery, readying the pistol for the next shot.
Premature Recoil Spring Wear
Because the 10mm Auto cartridge generates high pressures, the recoil spring in the Glock 20 Gen 5 undergoes significant stress.
Signs of Wear: Symptoms of a worn recoil spring can include sluggish cycling, erratic ejection patterns, and increased felt recoil. The slide may not fully cycle, leading to malfunctions.
Potential Solutions: The most practical solution is to replace the recoil spring assembly at regular intervals, often around 3,000-5,000 rounds, depending on the power of the ammunition used and shooting style. Replacing the recoil spring assembly is relatively inexpensive and easy to do.
Ammo Compatibility and Sensitivity
The Glock 20 Gen 5, while generally reliable, can sometimes exhibit ammunition sensitivity. This means that it may perform better with certain types or brands of 10mm Auto ammunition.
Difficulty with Certain 10mm Ammunition
Some owners have reported that their Glock 20 Gen 5s function more reliably with some ammunition brands compared to others. This may be due to variations in powder burn rates, bullet weights, or overall quality control.
Possible Causes: Low-powered ammunition may not generate enough energy to fully cycle the slide. Inconsistent powder burn can cause erratic ejection or failure to cycle.
Potential Solutions: Experiment with different ammunition brands and bullet weights. If you experience persistent issues with a specific brand, consider switching to a different load. Ensure you are using ammunition designed for firearms and not for sub-machine guns or other platforms.
Trigger Experience
The trigger on the Glock 20 Gen 5, while functional, is not necessarily known for its exceptional feel, especially for those accustomed to custom trigger upgrades.
Glock “Factory Trigger” Feel
The factory trigger is a safety-oriented design, often resulting in a longer trigger pull and a distinct “wall” or break point.
Potential Solutions: Some shooters replace the trigger, connector, or trigger spring to alter the trigger pull weight, shorten the travel, and create a crisper break.
Magazine Reliability
Magazines play a vital role in reliable function. Issues with magazines can manifest as feeding issues or the magazine falling out during shooting.
Magazine Issues
Problems can prevent the pistol from firing.
Solutions: Inspect the magazine for damage, clean it thoroughly, and replace the magazine if the problem persists. Using quality magazines is critical.
Essential Steps: Troubleshooting and Upkeep
Consistent care and maintenance can prevent many problems from arising in the first place.
Routine Cleaning and Preventive Maintenance
Regular cleaning is fundamental to reliable function.
Importance of Regular Cleaning: Cleaning removes carbon buildup, fouling, and debris that can interfere with function. Cleaning also allows you to inspect the gun for any damage or excessive wear.
Recommended Cleaning Procedures: Disassemble the pistol according to the manufacturer’s instructions. Use appropriate cleaning solvents and lubricants. Pay particular attention to the barrel, chamber, slide rails, and trigger mechanism.
Thorough Inspections
Inspecting your Glock 20 Gen 5 regularly will assist in detecting potential problems before they escalate.
Key Components to Inspect: Regularly examine the slide for cracks, the barrel for obstructions, the extractor for wear or damage, the ejector, the recoil spring assembly, and the magazines for any signs of damage.
Do-It-Yourself Solutions (When Appropriate)
Some minor issues may be remedied by owners with some basic knowledge.
Simple Fixes: The removal of a stuck case, cleaning the firing pin channel, or simple lubrication are often possible.
Safety Concerns: Always prioritize safety and be sure to familiarize yourself with safe handling procedures. Be certain to follow the instructions of the manufacturer. Never attempt to alter parts or make adjustments you are not certain of.
Seeking Professional Assistance
If an issue is beyond your level of expertise, always seek professional help.
When to Contact a Gunsmith: Any serious malfunctions or mechanical issues should be addressed by a qualified gunsmith.
Comparing Generations
The Gen 5 version of the Glock 20 has addressed and improved on some issues that were more common in earlier generations. For example, improvements to the extractor design and the use of a Marksman barrel.
Conclusion
The Glock 20 Gen 5 is a powerful, reliable firearm that is well-regarded. Potential problems can occur, including ejection issues, ammunition sensitivity, and trigger preferences. However, through regular maintenance, responsible ammunition selection, and prompt attention to malfunctions, Glock 20 Gen 5 owners can significantly mitigate these risks and maintain their firearm’s performance. While these potential issues should be kept in mind, the Glock 20 Gen 5 remains a formidable and popular choice for those seeking a high-powered pistol. Always follow safe gun handling practices.
