5 Glock 20 Problems & Fixes of Glock 20
1. Feeding Issue
So, I’m out on the field and noticed something odd with my Glock 20, particularly when using hotter loads like Underwoods 180gr TMJ.
The thing doesn’t want to feed the ammo right. I’m like, “What gives?” After digging, I found it’s an issue with high slide speeds. Turns out both the gen 3 heavier RSAs and the gen 4 dual spring can worsen the feed issues.
But hey, it’s not just the gun; your grip matters, too. Hold it too tightly, and you might compound the problem.
How To Fix
Alright, onto the good stuff: fixing this annoying issue. After some tinkering, I came across a few solutions that genuinely worked for me. First off, I swapped out some springs for wolf springs and updated the followers.
You won’t believe how much that alone helped. Also, loosening my grip a bit made a world of difference. But why stop there? Polishing the feed ramp also proved useful; it is smooth as butter now.
Finally, I decided to change the stock barrels for LW barrels. Boy, were they more dependable and accurate. With these adjustments, my Glock 20 feeds like a champ, no matter the ammo.
2. Extractor Issue
Alright, here’s another kicker I noticed while firing my Glock 20. About every 15 to 30 rounds, I faced an issue where the next round just wouldn’t feed.
The slide would sit right behind the next round, while the casing of the last round was halfway stuck in the chamber.
Pretty inconvenient, right? After inspecting the firearm, I realized the plunger pin had been dislodged, affecting the extractor.
Another culprit could be a faulty extractor that might fail over time, especially if you’re using overcharged bullets.
How To Fix
So, how did I tackle this? First, I performed a thorough slide teardown. I wanted to identify anything that could mess with the extractor tension.
The initial findings were clear: something was off. My go-to solution involved using a 22-pound caught flat spring RSA, and let me tell you, it made a noticeable difference.
But the real game-changer? Switching out the extractor entirely. I also spent more time at the range, refining my technique and letting the gun settle into its new setup.
End result: the feeding issue is history. It’s all about knowing your hardware and making those adjustments, folks.
3. Problem with the Recoil Spring
So there I was, laying down some heavy loads with my Glock 20, and I started noticing something concerning. The frame seems to be taking a beating from the stock RSA, and I’m thinking, “This can’t be good.”
It became clear that the RSA wasn’t robust enough to handle these powerful rounds consistently.
Adding to the mix, the Gen 4 RSA has this tendency to stack up when it’s new, which can stop slide-to-frame contact even under really high loads. All in all, it’s a situation that could lead to long-term damage if not addressed.
How To Fix
First, you should check the frame right in front of the front slide lugs. This is where the slide’s gonna hit during recoil. If you see some wear or even plastic starting to deform, you’re gonna need a sturdier spring.
In my own hands-on experience, I found that using a 22lb flat IMSI recoil spring assembly with a KKM barrel worked wonders. These KKM barrels are top-notch; they fit well and are incredibly well-machined.
After making these changes, the recoil spring problem was totally sorted. No more frame battering, and the gun could handle those heavy loads like a champ.
4. Jamming Problem
While out on the range with my Glock 20, I noticed a consistent issue: jamming. Now, let me tell you, a jammed gun is not just frustrating; it’s also potentially dangerous.
The bullet wouldn’t fully eject from the chamber, leaving me in a bit of a pickle. There could be a number of reasons for this issue, from a dirty firearm and damaged magazine to just plain weak ammunition.
Essentially, you’re dealing with a firearm that’s not functioning the way it’s supposed to, and that’s something you want to fix right away.
How To Fix
Alright, let’s get into how I tackled this annoying issue. First off, I disassembled my Glock 20 and gave it a thorough cleaning.
Make sure to get into all those tiny spaces where dirt can accumulate. Secondly, I checked the magazine. If it’s damaged or not fully seated, that can definitely contribute to jamming issues.
I also lubricated all moving parts with the right gun oil; don’t skimp on this step. Last but not least, I experimented with different brands of ammunition.
What you want is quality ammo that works well with your firearm. And guess what? The jamming issue was history.
5. Issues with the Trigger
Alright, let’s dive into another issue I encountered while shooting hotter loads with my Glock 20. In terms of cycling and shooting, everything seemed fine with regular ammo.
But the moment I switched to the hotter loads, I noticed the trigger wasn’t resetting. That’s a serious problem because, well, if the trigger isn’t resetting, you can’t fire your next shot smoothly.
Upon further inspection, I realized that the spring in the trigger mechanism had slipped to one side.
This was due to the updated trigger bars, and the misalignment caused the side of the housing to rub against the bar.
How To Fix
So, what’s the fix for this issue? Thankfully, it’s not too complicated. You can make adjustments without even having to disassemble the pistol.
What I did was take a thin instrument, in my case, the rear edge of a small paring knife, and gently push down on the misaligned spring.
Voila! The spring flipped back to its rightful place in the center. A few test rounds later confirmed that the trigger was resetting perfectly with the hotter loads. Problem solved.
Alright, let’s wrap things up. I’ve taken my Glock 20 out for a spin many times, and while it’s a pretty reliable piece of machinery, it’s got its share of issues.
Don’t let these issues deter you; use them as a learning experience. With proper maintenance and the correct adjustments, you’re not just fixing glock 20 problems; you’re optimizing performance.
The end game is a more reliable, efficient, and safer firearm. So yeah, while the Glock 20 isn’t without its faults, it’s a firearm you can count on once you’ve got it dialed in.
