Common Ejection Issues
The Glock 20 Gen 4 is a popular firearm. But, users have reported some common ejection issues. These issues can affect the gun’s reliability and performance. Let’s explore the most common problems.

One common issue is the failure to eject spent casings. This problem can cause the gun to jam. Users have to manually clear the jam. This can be frustrating during shooting sessions. The cause can be weak ammunition or an extractor problem. Regular maintenance can help reduce this issue.
Casing Damage
Another problem is casing damage during ejection. Damaged casings can cause feeding issues. They can also affect the gun’s performance.

Feeding Problems
Feeding problems can frustrate any firearm owner. The Glock 20 Gen 4, though reliable, can face issues. This post will cover common feeding problems and solutions.
Understanding these issues will help you maintain your Glock 20 Gen 4. Let’s dive into the details.
Failure To Feed
Failure to feed occurs when a round does not enter the chamber. This can result from several factors. One common cause is a dirty or damaged magazine. Ensure the magazine is clean and in good condition.
Another factor is weak ammunition. Weak rounds may not cycle the slide properly. Use high-quality ammunition to avoid this problem. Also, check your grip. A weak grip can cause feeding issues. Hold the firearm firmly and practice proper shooting techniques.
Inspect the recoil spring as well. A worn-out spring can cause failures to feed. Replace it if necessary. Regular maintenance will keep your Glock 20 Gen 4 running smoothly.
Double Feeding
Double feeding is another feeding problem. This happens when two rounds try to enter the chamber at once. It can be dangerous and frustrating.
First, check your magazine. A damaged or faulty magazine can cause double feeding. Replace it if needed. Also, examine the extractor. A broken or worn extractor may not remove spent cases properly.
Double feeding can also result from user error. Ensure proper loading and handling techniques. Keep your firearm clean and well-maintained. Regular cleaning prevents buildup that can cause feeding issues.
By addressing these factors, you can reduce double feeding problems. Keeping your Glock 20 Gen 4 in top condition ensures reliable performance.

Trigger Malfunctions
The Glock 20 Gen 4 is a popular choice among firearm enthusiasts. Despite its popularity, it has some issues. One common issue is trigger malfunctions. These problems can affect the performance and safety of the gun. Let’s explore two main trigger malfunctions: trigger reset issues and trigger pull resistance.
Trigger Reset Issues
Trigger reset issues can be frustrating. The trigger should reset quickly after firing. Sometimes, the trigger does not reset properly. This means you cannot fire the next shot quickly. This problem can occur due to dirt or wear. Regular cleaning can help reduce this issue. If the problem persists, a gunsmith may need to check it.
Trigger Pull Resistance
Trigger pull resistance is another problem. The trigger pull should be smooth and consistent. Sometimes, the trigger feels stiff. This can affect accuracy and control.

If the problem continues, professional help may be required.

Some users find the slide locks back unexpectedly. This can disrupt shooting sessions. The slide might lock back even with rounds still in the magazine. This issue can be frustrating for many shooters. It may be due to the slide stop lever. It can engage the slide during recoil. Regular cleaning and proper lubrication can help. But, persistent issues may require professional inspection.
Recoil Spring Wear
The recoil spring in the Glock 20 Gen 4 is crucial. It absorbs the energy during firing. But, it can wear out over time. Worn recoil springs can cause malfunctions. These include failure to feed and ejection issues. Regular inspection of the recoil spring is vital. Replace it if you notice signs of wear. This ensures smooth operation and reliability.
