• Light Primer Strikes: This is when the firing pin strikes the primer but fails to ignite the cartridge.
• Magazine Issues: Problems can include failure to feed, magazine not seating properly, or rounds not loading correctly into the magazine.
• Slide Lock Issues: The slide may fail to lock back after the last round or lock back prematurely.
• Trigger Issues: This can include a mushy trigger, failure to reset, or an overly heavy trigger pull.
• Accuracy Problems: Some users have reported issues with the accuracy of the Glock 17 Gen 5.

These issues can stem from various factors, including ammunition type, maintenance practices, and the firearm’s internal components. We will explore each of these problems in detail, providing potential causes and solutions.

Understanding the Glock 17 Gen 5: A Foundation for Troubleshooting

Before diving into specific problems, let’s briefly review the key features of the Glock 17 Gen 5. This understanding will provide a solid foundation for diagnosing and resolving potential issues. The Gen 5 incorporates several enhancements over previous generations, including:

• Glock Marksman Barrel (GMB): Enhanced rifling for improved accuracy.
• Ambidextrous Slide Stop Lever: Allows for easier operation for both left- and right-handed shooters.
• nDLC Finish: A more durable and corrosion-resistant finish.
• Flared Magazine Well: Facilitates faster and easier magazine changes.
• Absence of Finger Grooves: Provides a more comfortable grip for a wider range of hand sizes.

These features contribute to the overall performance and reliability of the Glock 17 Gen 5. However, understanding how these components function is essential for effective troubleshooting.

Troubleshooting Failure to Extract (FTE)

Failure to Extract (FTE) is a common issue that can occur with any semi-automatic pistol. In the Glock 17 Gen 5, FTE can be caused by several factors:

• Weak Ammunition: Underpowered ammunition may not generate enough energy to fully cycle the slide and extract the spent casing.
• Dirty Chamber: A dirty or fouled chamber can create friction, preventing the casing from being extracted smoothly.
• Worn Extractor: The extractor is responsible for gripping the casing rim and pulling it out of the chamber. A worn or damaged extractor may not provide sufficient grip.
• Extractor Spring Issues: A weak or broken extractor spring can also lead to FTEs.

Troubleshooting Steps:

1. Check Ammunition: Try using different brands or types of ammunition. Ensure the ammunition is within the recommended specifications for the Glock 17 Gen 5.
2. Clean the Chamber: Thoroughly clean the chamber with a chamber brush and solvent. Remove any carbon buildup or debris.
3. Inspect the Extractor: Examine the extractor for any signs of wear or damage. Replace the extractor if necessary.
4. Check the Extractor Spring: Replace the extractor spring with a new one.

Addressing Failure to Eject (FTEj)

Failure to Eject (FTEj) occurs when the spent casing is extracted from the chamber but not fully ejected from the firearm. Common causes include:

• Weak Ejector: The ejector is responsible for kicking the spent casing out of the ejection port. A worn or damaged ejector may not provide enough force.
• Ejector Spring Issues: A weak or broken ejector spring can also contribute to FTEj.
• Grip Issues: A weak or limp-wristed grip can absorb energy from the slide, preventing it from cycling fully and ejecting the casing.

Troubleshooting Steps:

1. Inspect the Ejector: Examine the ejector for any signs of wear or damage. Replace the ejector if necessary.
2. Check the Ejector Spring: Replace the ejector spring with a new one.
3. Improve Grip: Focus on maintaining a firm and consistent grip. Ensure your wrist is locked and your arms are extended.

Resolving Light Primer Strikes

Light primer strikes occur when the firing pin strikes the primer but fails to ignite the cartridge. Potential causes include:

• Ammunition Issues: Some ammunition may have harder primers that require a stronger strike.
• Firing Pin Channel Obstruction: Debris or oil buildup in the firing pin channel can impede the firing pin’s movement.
• Weak Firing Pin Spring: A weak or broken firing pin spring can reduce the force of the strike.

Troubleshooting Steps:

1. Check Ammunition: Try using different brands or types of ammunition.
2. Clean the Firing Pin Channel: Disassemble the slide and thoroughly clean the firing pin channel with a solvent.
3. Replace the Firing Pin Spring: Replace the firing pin spring with a new one.

Magazine-Related Problems and Solutions

Magazine issues can manifest in various ways, including failure to feed, magazine not seating properly, or rounds not loading correctly. Common causes include:

• Damaged Magazine Lips: Bent or damaged magazine lips can prevent rounds from feeding properly.
• Weak Magazine Spring: A weak magazine spring can cause rounds to sit too low in the magazine, leading to feeding issues.
• Dirty Magazine: Debris or carbon buildup inside the magazine can impede the movement of the rounds.

Troubleshooting Steps:

1. Inspect Magazine Lips: Examine the magazine lips for any signs of damage. Replace the magazine if necessary.
2. Replace Magazine Spring: Replace the magazine spring with a new one.
3. Clean the Magazine: Disassemble the magazine and thoroughly clean it with a solvent.

Addressing Slide Lock Issues

Slide lock issues can involve the slide failing to lock back after the last round or locking back prematurely. Potential causes include:

• Thumb Interference: A shooter’s thumb may inadvertently press on the slide stop lever, preventing the slide from locking back.
• Worn Slide Stop Lever: A worn slide stop lever may not engage properly with the magazine follower.
• Weak Magazine Follower Spring: A weak follower spring may not exert enough upward pressure to activate the slide stop lever.

Troubleshooting Steps:

1. Adjust Grip: Ensure your thumb is not interfering with the slide stop lever.
2. Inspect Slide Stop Lever: Examine the slide stop lever for any signs of wear. Replace the slide stop lever if necessary.
3. Replace Magazine Follower Spring: Replace the magazine follower spring with a new one.

Troubleshooting Trigger Issues

Trigger issues can range from a mushy trigger feel to failure to reset or an overly heavy trigger pull. Potential causes include:

• Dirty Trigger Mechanism: Debris or oil buildup in the trigger mechanism can affect its function.
• Worn Trigger Components: Worn trigger components can lead to a mushy or inconsistent trigger pull.
• Incorrect Trigger Installation: If the trigger has been replaced or modified, incorrect installation can cause problems.

Troubleshooting Steps:

1. Clean the Trigger Mechanism: Thoroughly clean the trigger mechanism with a solvent.
2. Inspect Trigger Components: Examine the trigger components for any signs of wear. Replace worn components as needed.
3. Verify Trigger Installation: If the trigger has been replaced or modified, ensure it is installed correctly. If you are not comfortable with this, consult a qualified gunsmith.

Addressing Accuracy Problems

While the Glock 17 Gen 5 is generally accurate, some users have reported issues. Potential causes include:

• Shooter Error: Inconsistent grip, trigger pull, or sight alignment can affect accuracy.
• Ammunition Issues: Some ammunition may be less accurate than others.
• Loose Sights: Loose sights can shift during firing, affecting accuracy.
• Barrel Issues: Rarely, there can be manufacturing defects in the barrel that affect accuracy.

Troubleshooting Steps:

1. Practice Proper Shooting Technique: Focus on maintaining a consistent grip, trigger pull, and sight alignment.
2. Try Different Ammunition: Experiment with different brands and types of ammunition.
3. Check Sight Tightness: Ensure the sights are securely mounted to the slide.
4. Inspect the Barrel: Have a qualified gunsmith inspect the barrel for any defects.
