Understanding the Glock 17 Magazine and Its Vital Spring
The Role of the Glock 17 Magazine Spring
At its core, the Glock 17 magazine is a robust and straightforward device. Designed to hold cartridges in a ready-to-feed configuration, it plays a pivotal part in the semi-automatic action. The magazine itself consists of a body, a baseplate, a follower, and, of course, the spring. It’s within this small enclosure where a complex dance of mechanics occurs to ensure reliable cycling of rounds.
The mag spring is the unsung hero within this system. Its primary duty is to apply constant upward pressure to the rounds within the magazine. As each round is fired and the slide cycles back, the spring forces the next round into the path of the slide, ready to be chambered. This continuous feeding process relies entirely on the mag spring’s consistent performance. Without adequate upward force, the rounds will fail to feed properly, resulting in malfunctions and a frustrated shooter. It also ensures the follower, the piece that pushes the rounds upward, engages with the slide’s slide stop to lock the slide back after the last round.
Construction and Design
Mag springs are usually constructed from high-quality spring steel. This material is selected for its elasticity, durability, and resistance to fatigue. The precise design, including the wire gauge and number of coils, are carefully engineered to provide the necessary force while fitting inside the confined space of the magazine. The design is critical because the spring must not only provide enough force to feed the rounds but also compress and store energy for consistent feeding even when the magazine is fully loaded.
Identifying the Symptoms of a Worn or Failing Mag Spring
Common Malfunctions
A malfunctioning mag spring can disrupt the reliable operation of your Glock 17, leading to a variety of performance issues. Early recognition of these problems can save you from frustrating experiences at the range or, more importantly, from malfunctions when it matters most.
One of the most common symptoms of a worn mag spring is failure to feed. The slide might fail to strip a round from the magazine, leaving you with a jam. The round might catch on the feed ramp or fail to chamber entirely. This often manifests as the slide moving partially forward, then getting stuck.
Other Potential Issues
Another related issue is failure to eject. Although not *directly* caused by the mag spring in most cases, a weakened spring can sometimes exacerbate ejection problems, especially if the weakened spring’s inability to fully hold up rounds causes those rounds to be weakly chambered or poorly aligned. A poorly aligned round might fail to extract completely.
The slide failing to lock back on the last round fired is also a telling sign. The follower, guided by the spring, is what typically actuates the slide stop. A weakened spring may not provide sufficient upward pressure to engage the slide stop, which means the slide won’t stay open after the final shot.
If the magazine is dropping freely or falling out of the gun when it should be held in place, it could indicate a problem with how the magazine itself is seated, the catch, or a combination. Still, a weak spring can also indirectly contribute to this issue, because it may not be applying enough pressure to the top of the mag.
Finally, difficulty loading rounds into the magazine can be a warning sign. A worn spring may make it harder to depress the follower to insert the next round, indicating that the spring is not providing the necessary resistance.
Visual Inspection
Visually inspecting your mag spring is a valuable practice. Examine the coils for any signs of compression, where they appear flattened or misshapen. Also, look for rust, corrosion, or other degradation that could compromise its functionality. Check the spring’s “springiness”—how easily it returns to its original shape after compression. A spring that feels limp or lacks tension is nearing the end of its useful life.
Ignoring these warning signs can compromise both the reliability and safety of your Glock 17. A malfunction during a training session might be inconvenient, but one during a self-defense situation could have far more serious consequences.
Replacing the Glock 17 Mag Spring: A Step-by-Step Guide
What You’ll Need
Fortunately, replacing a Glock 17 mag spring is a straightforward task that most gun owners can perform with confidence. It requires no special skills or tools.
Before you start, gather your supplies. You’ll need a replacement Glock 17 mag spring, which are readily available from online retailers and gun stores. Protective eyewear is also recommended. If you have one, a magazine disassembly tool can make the process a little easier, but it’s not mandatory. Finally, gloves are optional, but they can help keep your hands clean.
Disassembly Process
The first and most important step is to ensure your magazine is completely empty. Remove all rounds and visually confirm that the magazine is clear before proceeding.
Now, to disassemble your magazine. The precise method will depend on your magazine design, but the general process is as follows:
- Locate and depress the baseplate retaining button (or use the disassembly tool to compress the baseplate).
- Slide the baseplate off of the magazine body. Be careful, as the spring is under tension.
- Carefully remove the follower and spring from the magazine body. If using a disassembly tool, it helps to retain pressure to keep things from flying out.
Inspection and Reassembly
With the magazine disassembled, you can inspect the components, including the spring, for any additional signs of damage or wear.
Installing the new spring is the reverse of disassembly. Insert the new spring into the magazine body, ensuring the correct orientation (the spring may taper, and the fatter end often goes to the top). Align the follower over the spring. Carefully slide the baseplate back into position, ensuring it locks securely.
Testing
After reassembly, test your work. Load a few rounds into the magazine, and manually cycle the slide to ensure that the rounds feed properly. If the slide consistently locks back after the last round, that’s another good indicator of proper function. If you experience any issues, disassemble the magazine again to re-inspect the components and ensure correct assembly.
Exploring Aftermarket Options: The World of Mag Spring Upgrades
Types of Upgrades
While the factory Glock 17 mag spring is typically reliable, some shooters choose to explore aftermarket options. These upgrades often feature alternative materials or spring rates.
Aftermarket mag springs are available in a variety of configurations. Some are made from stainless steel, which is often touted for its resistance to corrosion. Others may feature an increased spring rate, which provides greater upward force.
Benefits of Upgrading
The potential benefits of an upgraded mag spring are primarily centered around improving reliability and extending the spring’s lifespan. However, you’ll want to do your research and choose a reputable brand. A more robust spring could potentially enhance feeding, especially in harsh conditions or with ammunition with slightly different dimensions. A longer-lasting spring will reduce the frequency of replacements, saving you time and money in the long run.
Potential Drawbacks
It’s essential to be aware of potential drawbacks. Some aftermarket springs may have compatibility issues with certain magazine designs or ammunition types. A stronger spring could place additional stress on the follower or other magazine components, potentially shortening their lifespan.
Making the Right Choice
Ultimately, the decision to upgrade your mag spring is a personal one. The factory spring usually works reliably. Before making a purchase, consider your needs, your shooting style, and your expectations. If you decide to upgrade, look for reputable brands that are known for quality and reliability.
Maintaining Your Glock 17 Magazines for Peak Performance
Cleaning Practices
Proper care and maintenance of your Glock 17 magazines are essential for maximizing their lifespan and ensuring reliable performance.
Cleaning your magazines regularly is crucial. Use a soft brush, a dry cloth, and potentially some mild cleaning solutions to remove any debris or powder residue. Avoid harsh chemicals that could damage the components. Also, use compressed air to clear out any lingering particles. Be sure to disassemble your magazines periodically to thoroughly clean all parts.
Lubrication and Storage
Lubrication should be used sparingly. A light application of a dry lubricant, such as a PTFE-based spray, may help prevent corrosion. Avoid using excessive amounts of lubrication, which could attract dirt and grime.
How you store your magazines can also impact spring longevity. Avoid storing loaded magazines for extended periods, as this can cause the spring to compress. Store them unloaded in a cool, dry place, out of direct sunlight and extreme temperatures.
Regular Inspections
Periodically inspect your magazines for wear and tear. Look for any signs of damage, such as dents, cracks, or deformation. Replace any damaged components immediately to prevent further issues.
Troubleshooting Common Issues
Even with regular maintenance, you might encounter occasional problems with your Glock 17 magazines. Some of the most common include:
If your magazine fails to lock back the slide after the last round, the mag spring is the usual culprit. Inspect and replace it. However, ensure the slide stop lever isn’t damaged or blocked. Check the follower, and ensure that it is making proper contact with the slide stop.
Failure to feed is another frustrating issue that can stem from various problems. A weak or worn mag spring, as we know, is a likely cause. However, other factors may be involved, such as a dirty magazine, damaged feed lips, or ammunition problems. Try different types of ammunition to determine if the problem is ammo-specific.
If the magazine won’t drop freely from the magazine well, check to make sure the magazine release button is working correctly. If the magazine is excessively worn or damaged, it may also be the cause.
