Ejection Issues, Unwanted Brass to Face
One of the more frequently cited concerns with the Glock 19 Gen 4 involves ejection issues, often manifesting as “brass to face” (BTF). This occurs when the spent cartridge casing fails to eject properly, sometimes striking the shooter in the face or the side of their head. This can be more than just an annoyance; in a self-defense situation, a malfunction can be dangerous.
Several factors can contribute to these ejection problems. The original design of the Gen 4 saw some revisions, including changes to the ejector design compared to previous generations. While intended for other performance benefits, these changes, in certain circumstances, could impact the ejection process. Further, the extractor, the part responsible for grabbing the spent casing and pulling it from the chamber, may exhibit less consistent tension in some pistols. This variation can sometimes affect the reliability of extraction. The extractor’s ability to firmly grip the casing is crucial for preventing issues.
Moreover, the ammunition itself plays a role. Some Glock 19 Gen 4 pistols may be more sensitive to the specific characteristics of the ammunition being used. This sensitivity can manifest as unreliable ejection when certain brands or bullet weights are employed. The geometry of the cartridge, the propellant used, and even the crimp of the bullet can all influence the ejection process.
Fortunately, solutions are available to address these ejection problems. A common solution is to replace the factory ejector with an updated or more robust version. Various aftermarket ejectors are designed to improve ejection reliability, often providing more consistent and forceful ejection. Assessing and potentially adjusting the tension of the extractor is another step. A competent gunsmith can assess the extractor and make adjustments. Examining and, if necessary, replacing the magazine can also help. Worn or damaged magazines can contribute to feeding and extraction difficulties. Experimenting with different ammunition types may also be beneficial. Trying various brands and bullet weights will allow the shooter to determine which types perform most reliably in their particular Glock 19 Gen 4. It’s essential to determine the root cause and employ the correct solution.
Trigger Troubles, Smoothness and Function
The trigger is a critical component of any firearm, and the Glock 19 Gen 4 is no exception. While generally praised for its simplicity, the trigger system is prone to certain issues over time, or with improper use or maintenance. Users sometimes report a gritty or inconsistent trigger pull. This may manifest as a sensation of roughness during the trigger press, making accurate and controlled shooting more difficult.
One primary cause of a less-than-ideal trigger pull is the wear and tear of the trigger components. Like any mechanical system, the trigger mechanism experiences friction and stress during use. Over time, this can lead to wear on the trigger bar, connector, and other internal parts, resulting in an uneven and potentially unpredictable trigger pull.
Insufficient lubrication can further exacerbate trigger issues. The Glock 19 Gen 4’s trigger components require proper lubrication to function smoothly. If the gun is not cleaned and lubricated adequately, the trigger parts may experience increased friction, leading to a gritty feel.
Debris, such as unburnt gunpowder residue, dirt, and other contaminants, can also accumulate inside the trigger mechanism. This buildup can interfere with the proper functioning of the trigger parts, contributing to an uneven or unreliable trigger pull.
Fortunately, these trigger issues are usually addressed with relatively simple measures. A thorough cleaning and lubrication of the trigger mechanism is often the first step. Disassembly and meticulous cleaning of the trigger parts to remove any debris is critical. Lubricating the components with a high-quality gun lubricant is important. If the trigger pull persists or is very bad, replacing worn parts is also a viable solution. The trigger bar, connector, or other key components may require replacement to restore smooth operation.
While aftermarket trigger upgrades are available, it is important to research such upgrades well. Some may offer significant performance enhancements, while others may introduce reliability issues. The user should understand that any aftermarket trigger modifications may also affect the gun’s warranty.
Dealing with Issues Involving the Guide Rod
The guide rod, or recoil spring assembly (RSA), is a crucial component in the Glock 19 Gen 4, responsible for guiding the slide during recoil and returning it to battery after each shot. Problems with the guide rod, or RSA, can significantly impact the firearm’s function. The guide rod itself may break, or the RSA may fail to fully return the slide to the forward position after firing.
The use of aftermarket guide rods can be a contributing factor to such issues. While some aftermarket guide rods are made from quality materials, some can introduce problems. If the guide rod is not correctly designed or made with inferior materials, it may not function correctly and can lead to damage. Poorly designed or incompatible guide rods can potentially cause the slide to bind or fail to cycle properly. Improper disassembly or reassembly of the firearm can also damage the guide rod. Bending, distorting, or improperly seating the guide rod during the maintenance process can lead to malfunctions.
The guide rod and its associated recoil spring are subject to wear and tear over time. The constant compression and decompression cycles during firing can eventually weaken the spring, leading to decreased performance.
Solutions often include replacing a defective guide rod with a quality factory or aftermarket replacement, and being sure to replace the RSA periodically. Following proper maintenance procedures, being very careful during disassembly and reassembly, and using quality parts will prevent many of these issues.
The Magazine’s Impact, Feed and Drop Concerns
Magazines are critical for reliable feeding, yet they, too, can sometimes create problems. Issues with magazines can disrupt the smooth operation of the Glock 19 Gen 4, leading to frustrating malfunctions. The magazines can sometimes fail to drop freely from the grip when the magazine release is activated. In some cases, the magazine might experience feeding issues, resulting in failures to feed or to properly chamber a round.
Damage to the magazine itself can cause these problems. Dropping the magazine onto a hard surface, for example, can result in denting, warping, or cracking, which can impede proper feeding and ejection. Wear and tear can also contribute to magazine issues. The spring inside the magazine provides the force necessary to push rounds upwards toward the chamber. As the spring is compressed and decompressed during use, it can weaken over time, causing feeding problems. Similarly, damage to the feed lips, the top portion of the magazine that holds the cartridges, can compromise reliable feeding. Finally, debris inside the magazine can interfere with the smooth movement of rounds. Debris, dirt, or other contaminants can obstruct the rounds from correctly aligning and feeding into the chamber.
Addressing magazine-related issues involves simple yet effective measures. Removing debris and other obstructions from the magazine can resolve many feeding problems. Cleaning the magazine thoroughly can help remove dirt, and other contaminants. Replacing the magazine spring with a new one can restore the magazine’s ability to properly feed rounds. Replacing the entire magazine with a new one is often the most effective solution if the magazine itself is damaged or worn out. Always check the feed lips for damage and replace the magazine if any wear is detected.
Recoil Spring Assembly Problems
The recoil spring assembly (RSA) is designed to absorb the energy of recoil and return the slide to battery. However, the RSA may fail due to wear and tear. The spring inside can break.
Wear and tear is the primary cause. The constant compression and decompression cycles during firing lead to metal fatigue. Over time, the spring can weaken and eventually fail.
The solution is to replace the RSA. Regular replacement intervals are recommended, which is often specified by the manufacturer or dependent on round count.
Surface Wear, Managing the Finish
Cosmetic wear and tear is a less-critical concern but can detract from the appearance of the pistol. The Glock 19 Gen 4’s finish is a durable one, but it is still subject to wear. Holstering and unholstering the firearm can cause wear on the slide finish, particularly along the edges. Handling the pistol, whether during training, shooting, or cleaning, can also lead to minor scratching or scuffing of the finish.
These cosmetic blemishes are usually a result of normal use. The consistent contact with the holster or other surfaces leads to some inevitable wear.
Solutions include considering refinishing methods such as Cerakote. Cerakote and other durable coatings provide a protective layer and can restore the pistol’s appearance. However, it is important to understand that this is primarily a cosmetic issue and does not affect the firearm’s function.
General Maintenance and Preventative Practices
A diligent approach to maintenance is crucial for maximizing the reliability of the Glock 19 Gen 4 and minimizing the likelihood of encountering the problems. Regular cleaning and lubrication are the cornerstones of preventative maintenance. Firearms should be thoroughly cleaned after each shooting session, removing carbon buildup, debris, and other contaminants. Use high-quality gun cleaning solvents and brushes to remove grime. After cleaning, apply a high-quality gun lubricant to all moving parts, including the slide rails, barrel, and trigger mechanism.
Regularly inspect the firearm, paying attention to critical components like the extractor, trigger components, and guide rod. Look for any signs of wear, damage, or unusual function. Check the extractor’s condition and the trigger pull’s feel. Periodically examine the guide rod and recoil spring for signs of wear.
Only use quality ammunition. The use of low-quality or improperly stored ammunition can lead to malfunctions. Proper storage is also important. Store the firearm in a secure, dry place. Avoid leaving the firearm exposed to extreme temperatures or humidity, as these conditions can damage the internal components.
