Understanding the Glock 19 Gen 5 Extractor
Function of the Extractor
The extractor is a crucial part of the Glock 19 Gen 5’s firing cycle. Its primary job is to remove the spent cartridge casing from the chamber after firing. As the slide moves rearward during the firing sequence, the extractor, which is designed to “grab” the rim of the spent case, pulls it out of the chamber and holds it until it contacts the ejector, which then kicks the case out of the gun. This is a critical process for ensuring the pistol cycles reliably and is ready to fire the next round. Without a properly functioning extractor, the weapon becomes prone to stoppages.
Components of the Extractor Assembly
The Gen 5 version of the Glock 19 features an extractor assembly consisting of several key components: the extractor itself, the extractor spring, and the spring loaded bearing, often called the “bearing”. The extractor is a small, precisely machined piece of metal, usually made from hardened steel, that latches onto the rim of the cartridge casing. The extractor spring provides the necessary tension to keep the extractor firmly engaged with the case. The bearing, sometimes with a spring, provides pressure. The interaction of these components is crucial for the proper operation of the firearm. Unlike earlier generations, the Gen 5 extractor underwent some design changes to optimize its performance and durability, though the core function remained the same.
Causes of a Loose Extractor
Normal Wear and Tear
The most common cause is simply wear and tear from regular use. Every time you fire your Glock 19 Gen 5, the extractor is subjected to stress and repeated impacts. Over time, these forces can lead to the following:
The extractor claw, the part that grips the cartridge rim, can wear down or become slightly deformed, reducing its ability to hold the case securely. Firing a high volume of rounds over an extended period accelerates this wear.
The extractor spring, which provides tension to the extractor, can weaken over time. This reduced tension decreases the extractor’s ability to grip the casing tightly.
The components within the firing pin channel, including the spring loaded bearing, can wear, potentially affecting the extractor’s function.
Manufacturing Defects
While Glock has an excellent reputation for quality, manufacturing defects can occasionally occur. These defects might manifest as:
An out-of-spec extractor, meaning the extractor might not have been manufactured to the correct dimensions, leading to improper fit and function.
A weak or defective extractor spring, which, as mentioned earlier, can reduce the extractor’s tension.
Poorly manufactured components within the extractor assembly. Even minor imperfections in the extractor itself or related parts can impact the overall performance of the system, contributing to a loose extractor.
Improper Maintenance or Installation
Improper maintenance or incorrect installation of parts can also contribute to the issue. Here are some examples:
Incorrect reassembly after cleaning can lead to the extractor not seating properly. It’s essential to follow the manufacturer’s instructions carefully during disassembly and reassembly.
Improper lubrication can cause the extractor to bind or malfunction. Over-lubrication can also attract dirt and debris, potentially hindering the extractor’s movement.
Using incorrect cleaning tools or cleaning methods can potentially damage the extractor or related components. For instance, using abrasive cleaners or harsh solvents could negatively impact the parts.
Issues with aftermarket parts. While aftermarket parts can enhance the performance of a Glock 19 Gen 5, using poorly made parts can contribute to extractor issues.
Specific Ammunition Factors
The type of ammunition used can also play a role.
Reloaded ammunition, especially if not manufactured to stringent standards, may have slightly different dimensions, leading to extraction problems.
Excess pressure generated by certain ammunition loads can put undue stress on the extractor and related components, potentially leading to premature wear or damage.
Symptoms of a Loose Extractor
Failure to Extract
This is often the most obvious symptom. Failure to extract (FTE) occurs when the spent casing fails to be completely removed from the chamber. This results in several potential scenarios:
The spent casing may remain partially in the chamber, with the new round attempting to feed into the same space. This is a major malfunction.
The spent casing might remain lodged in the chamber, requiring manual intervention to clear the stoppage.
Failure to Eject
Failure to eject (FTEJ) occurs when the spent casing is extracted from the chamber but doesn’t eject cleanly from the firearm.
Brass stovepiping. This happens when the spent casing becomes lodged in the ejection port, pointing upwards like a stovepipe.
Cases getting jammed in the ejection port, blocking the next round from feeding.
Inconsistent Ejection Pattern
A properly functioning Glock 19 Gen 5 will usually eject spent casings consistently. A loose extractor may cause the casings to eject in unpredictable directions, spraying brass in various directions.
Other Possible Symptoms
Occasionally, other symptoms may be associated with a loose extractor, especially if the problem is severe or compounded by other issues:
Occasional light primer strikes. While not directly caused by a loose extractor, other mechanical issues can cause these problems, which could, in rare instances, be tied to issues within the slide.
General reliability issues with the pistol. Multiple malfunctions or a general lack of confidence in the firearm’s function.
Troubleshooting a Loose Extractor
Visual Inspection
Begin with a thorough visual inspection.
Inspect the extractor claw for wear, damage, or deformation. Look closely at the grasping surfaces to see if they have lost their original shape.
Check the extractor spring for damage, corrosion, or signs of weakening.
Inspect the spring loaded bearing for wear and tear.
Inspect the breech face for any burrs or damage.
If you are unfamiliar with any of these steps, consider seeking assistance from a qualified gunsmith.
Functional Tests
Carefully perform several functional tests.
Try to manually remove a spent casing from the chamber. A loose extractor might not hold the case firmly, allowing it to slip out easily.
The “drop test.” This is a simple test. With the slide removed, hold the slide in your hand. Place a spent casing into the extractor. Then, carefully turn the slide upside down, allowing the casing to fall. If the extractor is loose, the casing should fall out easily.
Live fire test. Perform a live fire test in a safe and controlled environment. Observe the ejection patterns and note any malfunctions.
Checking Ammunition
Verify the ammunition used is within specification and not reloads if you are not familiar with the source.
Cleaning and Lubrication
Thoroughly clean and lubricate the extractor assembly and related parts. Remove any dirt, debris, or old lubricant. Use a quality firearm lubricant.
