Common Glock 19x Problems And Their Solutions

1. Failure To Feed

The “Failure to Feed” issue in a G19x can be frustrating and potentially dangerous. It occurs when the slide fails to fully chamber a 9mm round from the magazine, resulting in an incomplete action cycle.

Weak or worn springs, incorrect or damaged magazines, dirty firearms, and other related issues commonly cause this issue.

Fixing this issue can often be done relatively quickly and easily. The first step is to thoroughly inspect the firearm for any visible damage or obstruction that could affect its performance.

Afterward, the moving parts should be thoroughly cleaned using a quality lubricant.

Next, we recommend replacing any worn springs in the weapon with new ones and replacing any damaged magazines.

As a final step, we recommend performing several test cycles with dummy rounds to ensure the issue has been resolved.

2. Finish Problems

The “mottled appearance” is a common issue that Glock 19x owners may encounter. It is characterized by an uneven or inconsistent finish on the firearm’s slide and frame, typically caused by poor finishing methods during manufacturing or storage. This can result in a dull, spotty, or bluish-gray look to the gun’s surface.

Fortunately, this issue can be easily fixed with a few simple steps. First, the gun should be cleaned and lightly oiled to remove any dirt or debris that may have accumulated on the firearm’s surface.

The slide and frame can be buffed using a high-grade polishing compound if necessary.

This will help restore the firearm’s original luster and solve the mottled appearance. Additionally, applying a coat of wax or gun oil may help to protect the finish from future damage.

Finally, store your handgun in an appropriate environment; prolonged exposure to moisture or extreme temperatures can cause further issues with the firearm’s finish.

3. Failure To Eject

If you’re having issues with your gun not ejecting rounds properly, it could result from several different things.

One possible cause is that the magazine spring may be too weak and not give enough force to push the round out of the chamber fully.

It’s also possible that the extractor is malfunctioning or not properly gripping onto the case rim.

Fortunately, a few simple solutions can help you resolve this issue quickly and easily. First, make sure to clean the weapon thoroughly and inspect all of its internal components.

Replacing the extractor spring regularly is also recommended to maintain optimal performance. If your magazine springs are weak, try replacing them with a stronger version.

4. Magazine Issues

Some owners have experienced issues with the magazine not feeding correctly or properly inserted into the gun.

This issue is usually attributed to loose tolerances in the gun or a bad magazine spring, which can be easily fixed.

To remedy this issue, inspect the mag well for any debris or irregularities that might prevent the magazine from properly seating.

If nothing appears to be blocking it, check the magazine for any signs of damage, such as bent lips or dents in the body.

If there is no obvious damage, try replacing the spring with a new one for improved reliability and performance.

5. Jamming Issue 

This problem occurs when the slide fails to cycle correctly or the chamber has difficulty ejecting cartridges after firing.

Several factors, including dirt, debris, incorrect ammunition type, and improper lubrication can cause jamming.

Fortunately, you can take some simple steps to solve this issue.

First, ensure all ammunition used is appropriate for your handgun. Incorrect or poor-quality ammunition can cause jams and other problems with cycling.

Also, ensure the handgun is properly lubricated by applying a thin layer of lubricant to all moving parts of the gun. This will help keep everything running smoothly and reduce the chance of jamming.

If you are still having problems with your gun, make sure to clean it thoroughly. Dirt and debris can easily build up in the slide or barrel and cause jams.

Cleaning should include completely wiping all surfaces and thoroughly cleaning the chamber and barrel.

6. Firing Pin Breakage

Firing pin breakage is one of the most common issues. This issue occurs when the firing pin fails to return to its correct position after a successful firing.

Without proper maintenance, this can result in many problems.

Fortunately, you can easily fix this issue and prevent it from happening again. To do so, you must first thoroughly disassemble your firearm.

Carefully remove the firing pin assembly and inspect it for wear or damage.

If the firing pin has worn down, replacing it with a new one is time. You may also need to inspect the bolt of your pistol if significant wear or damage is observed in the firing pin assembly.

Once the firing pin has been replaced and the bolt inspected, you should also apply a light oil or lubricant coating to help ensure it will function properly.

7. Slide Stop Issues

Slide stop problems are one of the most common problems with this gun. When faced with this potential issue, it can be frustrating and lead to ammo jams or other malfunctions.

The slide stop is an important part of any firearm, and keeping it in working condition is essential for safe operation.

This could be caused by a worn-out or broken slide stop, an oversized magazine, or even dirt and debris accumulated in the firearm.

Replacing a worn-out or broken slide stop lever is usually the best option, as this will ensure the G 19x functions as it should.

If replacing the slide stop doesn’t solve the issue, inspect the firearm’s internals and ensure everything is free from dirt and debris.

You may also find that an oversized magazine is causing your issues with a slide stop. This happens when you insert a magazine not specifically designed for this handgun.

The oversized magazine can cause issues with the slide stop and should be replaced with an appropriate-sized magazine.

8. Trigger Reset Issues

Trigger reset issues can be one of the most frustrating problems with this pistol. This is an issue whereby the trigger does not reset completely into its ready position after being pulled and released.

This creates problems when firing multiple shots, as this will cause jams or misfires.

The first thing to do is check the trigger bar for any marks or burrs that might be causing it to stick in the sluggish trigger firing position. If you find any, smoothen them using a fine file or emery cloth.

You can also try adjusting the trigger pull weight if it’s too light or heavy. To do this, locate and remove the trigger connector. This small metal piece sits in the middle of the trigger.

You can increase or decrease its weight by increasing or decreasing the number of coils on its spring.

9. Slide Lock Prematurely Engaging

Shooters may experience a prematurely engaging issue with their slide lock. This issue occurs when the magazine doesn’t have enough upward pressure to keep the slide open, causing it to lock before the last round has been fired.

The first step in resolving this issue is to ensure that the magazine spring and follower are properly seated in the magazine body. If they are not, the magazine may lack adequate upward pressure to keep the slide open.

In some cases, replacing the magazine spring and follower with a stronger one, such as a Wolff Gunsprings brand upgrade, may be necessary.

This will give your Glock 19X more power when firing rounds and should resolve the issue of premature slide lock engagement.

Additionally, it is recommended that you clean and lubricate your Glock 19X regularly to ensure optimal performance.
