Common Glock 19 Gen 5 Problems And Their Solutions

1. Ejection Issues

Are you experiencing ejection issues with your Glock 19 Gen 5? Do spent casings fail to fully eject and get stuck in the ejection port? Are you experiencing stovepipes or double feeds? These are all common issues that Glock 19 Gen 5 owners face.

The main causes of ejection issues vary but typically arise from a dirty or worn extractor, incorrect extractor tension, a weak or worn ejector spring, or a dirty or stuck ejector.

If left unchecked, ejection issues can cause malfunctions, FTEs (failure to eject), and FTFs (failure to feed), which can become safety hazards that harm the shooter or others in the vicinity.

Thankfully, there are several ways to address ejection issues. The first step is to ensure your Glock 19 Gen 5 is properly lubricated and maintained.

Next, you can try cleaning the extractor and ejector, or replacing the extractor spring and/or ejector spring if needed. If that doesn’t work, you can try adjusting the extractor tension or replacing the extractor itself.

You should also inspect your type of ammunition, as some ammo is known to cause ejection issues.

Sometimes, if you’re struggling with similar issues, simply switching to a different brand or type of ammo can solve the problem.

2. Feeding Issues

The main causes of feeding issues in a Glock 19 Gen 5 can range from a dirty or damaged magazine to a weak recoil spring.

To fix feeding issues, you should start by ensuring that your Glock is clean and well-lubricated. This will allow the slide and barrel to move smoothly, reducing friction and potential misfeeds.

Additionally, you should inspect your magazine to make sure it’s in good condition and not damaged. Often, the feed lips can become bent or the spring can become weak, causing feeding issues.

If cleaning and inspecting your Glock and magazine don’t solve the problem, consider replacing the recoil spring.

Over time, these springs can become weak, causing the slide to cycle too slowly or not at all, resulting in feed failures.

By replacing the recoil spring with a high-quality replacement, you can ensure your Glock is functioning at its best.

3. Trigger Issues

Are you experiencing problems with the trigger of your Glock 19 Gen 5? Trigger issues are some of the most common problems that Glock users encounter.

The trigger mechanism consists of several different components, including the trigger pull, trigger bar, trigger spring, and trigger assembly.

Any of these parts can contribute to trigger issues that affect the gun’s performance or even make it unsafe to use.

One of the most common issues with the trigger of your Glock is a heavy or hard trigger pull.

This can be caused by several factors, including a dirty or worn-out trigger bar, improper lubrication, or a weak or broken trigger spring.

To fix this issue, it is important to perform regular cleaning and maintenance of your Glock. You can also consider replacing the trigger assembly or trigger spring to improve the pull weight.

Another issue you may encounter with your Glock’s trigger is a gritty or rough feeling when pulling the trigger. This can be caused by a buildup of debris or corrosion on the trigger bar or trigger assembly.

To resolve this issue, you can thoroughly clean and lubricate the trigger mechanism. In some cases, you may need to replace the trigger bar or trigger assembly.

Troubleshooting trigger issues can be a complex process, especially if you are not familiar with the inner workings of your Glock.

If you’re experiencing trigger problems, it’s important to seek out expert advice and assistance.

Always consult a qualified gunsmith or Glock specialist before attempting to repair or replace any components of your firearm.

4. Recoil Spring

One of the main causes of recoil spring problems is wear and tear. Over time, your Glock 19’s recoil spring may lose its tension or become damaged, making it less effective at absorbing recoil.

This can lead to malfunctions and feeding issues, making your firearm less reliable.

To fix this issue, you need to perform regular maintenance on your Glock 19, including cleaning and inspecting your recoil spring.

If you notice any signs of wear or damage, like cracks or fraying, it’s time to replace your recoil spring.

You can purchase a high-quality replacement spring from Glock or other reputable firearm parts dealers.

In addition to regular maintenance and replacement, there are a few other things you can do to prevent recoil spring problems in your Glock 19 Gen 5.

These include using high-quality ammunition that doesn’t put excessive wear on your firearm, avoiding overly aggressive shooting techniques, and ensuring that you use the correct recoil spring weight for your firearm’s setup.

5. Firing Pin Problems

The cause of this problem is usually due to wear and tear over time, causing the spring to weaken and eventually fail. But, there is a solution to this problem.

Firstly, inspect the round count of your pistol. The more rounds that have been fired, the more likely it is that the recoil spring needs to be replaced.

The recommended round count for replacing the spring is around 5,000 rounds.

Next, visually inspect the recoil spring for any signs of damage or wear and tear. Check around the firing pin for any debris or damage, which can cause issues with the recoil spring.

If you find any of these issues, it’s time to replace the recoil spring. This can be easily done with a simple disassembly of your Glock 19 Gen 5. Most replacement recoil springs can be found online or at your local gun shop.

However, if issues persist even after replacing the recoil spring, it may be necessary to seek the advice of a professional gunsmith. They will be able to identify any underlying issues and suggest appropriate solutions.

6. Barrel Issues

Are you experiencing problems with your Glock 19 Gen 5 barrel? Perhaps you’re noticing issues with accuracy or malfunctioning during firing. If this sounds like a familiar scenario, then barrel issues may be the root cause.

The main causes for Glock 19 Gen 5 barrel problems can vary, but some common culprits include improper cleaning or maintenance, lack of lubrication, and damage to the barrel from wear and tear.

These issues can not only hinder your firearm’s performance but also put you and any surrounding individuals in danger.

Thankfully, there are solutions available to fix these barrel problems. Regular cleaning and lubrication of your firearm can prevent build-up and damage.

Additionally, inspecting your firearm for any signs of wear and tear can help you identify and address any potential issues before they become problematic.

If you’re experiencing accuracy problems, consider having a professional gunsmith inspect and repair your firearm. They can identify any issues with the barrel’s rifling or chamber, which can significantly affect accuracy.

7. Slide Issues 

Many people face similar problems, and in most cases, these issues are related to the slide lock, obstructions, dirt, and debris.

Slide lock issues are predominantly caused by the engagement of the slide lock notch or the slide-out of the battery position. This problem is common with inexperienced shooters who may inadvertently manipulate the slide lock.

Obstructions in the slide are also another leading cause of slide issues, and they include foreign objects that may get lodged between the slide and the frame.

These objects can be anything from dirt, dust, hair, and debris.

They cause friction between the slide and the frame surface, which is detrimental to the slide’s movement.

Dirt and debris can also cause slide issues. The accumulation of debris around moving parts can cause a buildup of friction and prevent the slide from moving smoothly.

This problem is prevalent in firearms used in harsh environments or when they have not been subjected to regular maintenance.
