Common Issues with the Glock 19 Gen 5: Understanding and Addressing Problems


The Glock 19 Gen 5 is a popular choice among gun enthusiasts and law enforcement officers for its compact size, reliability, and ease of use. However, like any firearm, it is not without its share of issues. In this article, we’ll explore some common problems that users may encounter with the Glock 19 Gen 5 and discuss potential solutions.

1. Failure to Feed (FTF): 

One of the most reported problems with the Glock 19 Gen 5 is failure to feed. This occurs when a round is not properly chambered during the firing cycle. FTF can be caused by various factors, including dirty or worn magazines, weak magazine springs, or improper grip and shooting technique.


 To address FTF issues, it’s essential to keep the firearm and magazines clean and well-maintained. Additionally, ensure that you are using high-quality, factory-made ammunition that is compatible with the Glock 19 Gen 5. Proper grip and shooting stance can also help prevent FTF incidents.

2. Extractor Issues:

 Another common problem with the Glock 19 Gen 5 is extractor issues, where spent casings are not ejected properly from the chamber. This can result in stovepipes or other malfunctions, causing the firearm to jam.


Inspect the extractor for any signs of wear or damage, such as chips or cracks. Clean the extractor and the surrounding area thoroughly to remove any debris or fouling that may be affecting its performance. If necessary, consider replacing the extractor with a new one from Glock or a reputable aftermarket manufacturer.

3. Trigger Reset Problems: 

Some users have reported issues with the trigger reset on the Glock 19 Gen 5, where the trigger fails to reset properly after firing a round. This can affect follow-up shots and overall shooting performance.


Check the trigger assembly for any dirt, debris, or obstructions that may be preventing the trigger from resetting correctly. Clean and lubricate the trigger components as needed, and ensure that all parts are properly installed and functioning. If the problem persists, consult a qualified gunsmith or contact Glock for further assistance.

4. Slide Stop Malfunctions: 

Another potential issue with the Glock 19 Gen 5 is slide stop malfunctions, where the slide fails to lock back after the last round is fired. This can be frustrating for users, especially during training or competition scenarios.


Inspect the slide stop lever for any signs of wear or damage, and ensure that it is properly installed and functioning. Check the magazine follower and spring to ensure they are working correctly and not causing premature locking of the slide. If necessary, replace the slide stop lever with a new one from Glock or a reputable aftermarket manufacturer.


In conclusion, while the Glock 19 Gen 5 is a reliable and well-designed firearm, it is not immune to problems. By understanding common issues and implementing proper maintenance and troubleshooting techniques, users can address and mitigate potential problems with their Glock 19 Gen 5. As always, if you encounter persistent issues or are unsure how to address a problem, seek assistance from a qualified firearms professional.
