I’ve had the pleasure of testing the Glock 48 out in the field, and let me tell you, it’s a solid firearm. 

But in my time with this handgun, I’ve encountered common problems like recoil spring glitches, trigger issues, magazine mishaps, ejection problems, and instances where it didn’t return to battery properly.

Don’t worry though; I’ll break down each Glock 48 Problems, talk about what’s likely causing it, and throw in some solutions to get you back in action. Stick around; you won’t want to miss this.

Top 5 Glock 48 Problems & Solutions

1. Problems with the Recoil Spring

Okay, let’s move on to another gripe I had with the Glock 48: the recoil spring. While testing this bad boy, I realized that the slide didn’t always go all the way forward, especially when the trigger was engaged. 

Sometimes, it took a little nudge at the back of the slide to get things moving again. That’s definitely not what you’re looking for in a situation where reliability is key. 

If you have to manually help the slide along, then something’s not right, period.


So how do we fix this? First, I checked out the Recoil Spring Assembly (RSA) following Glock’s manual to see if it was up to par. 

You could be dealing with improper lubrication or even a weak recoil spring assembly. If it turns out the RSA isn’t strong enough, swap it out for a new one. 

It’s an easy fix, but ensure you adhere to the manual’s guidelines. If you’re not comfortable with this, a call to Glock’s customer service might be a good next step.

2. Trigger Problem

So, let’s dive right into it. One issue that really caught my attention while field-testing the Glock 48 was the trigger mechanism. You’d think it would be smooth sailing, right? Well, not quite. 

Even when the slide cycled as it should, the gun wouldn’t fully charge the battery unless I let go of the trigger. 

But wait, there’s more. As a new round came into position, the trigger just snapped forward all of a sudden. I mean, that’s not what you want when you’re depending on your firearm.


Now, let’s talk solutions. After scratching my head a bit and really getting into the nitty-gritty, I pinpointed a couple of potential culprits. 

First, the trigger bar’s “cruciform” could be misaligned, meaning it needs to sit just right in the hook of the trigger spring. Another possibility? A weak recoil spring assembly. 

But before you start taking things apart, I advise reaching out to Glock customer service. Trust me, they know their stuff and can guide you through it. 

You could also consider modifying the connector as a last resort, but make sure you know what you’re doing, alright?

3. Magazine Issue

Let’s talk about the last issue on the list, which is none other than the magazine. While out in the field, I experienced frequent disengagement from the magazine, causing it to drop. 

It didn’t matter if it was full, half-full, or nearly empty; this thing just wouldn’t stay put. And to top it off, there were times when the magazine seemed to get stuck midway as if some invisible force was blocking it. 

This is a significant disruption, especially if you’re in a situation where you need your firearm to perform flawlessly.


So, how do we tackle this? The root cause appears to be the Glock 48’s mag being too tight. This makes it difficult for the magazine to function efficiently, causing the disruptive behaviors I mentioned. 

Reach out to Glock. Seriously, just give them a call, describe the issue, and ask about upgrading to a later model. Also, in the meantime, try not to load more than ten rounds into the magazine. 

It might help alleviate the problem until you get a more permanent solution. Exercise caution if you’re thinking about modifying anything, and as always, stick to the manual.

4. Ejection Issue

Now, onto another issue that’s hard to ignore: ejection problems. Yep, you heard that right. While out testing the Glock 48, I found that the gun consistently failed to eject brass. 

It didn’t matter who was shooting or what type of ammunition or magazine was used. The extractor just couldn’t keep a grip on the shell, leading to a bunch of wasted brass. 

And let me tell you, the extractor was noticeably floppy, especially when I rotated the slide. Talk about frustrating!


Here comes the good part: I figured out what was going wrong. It turns out the housing/ejector assembly is usually the bad guy in this situation. 

Swapping out that assembly seems to do the trick most of the time. Another issue could be a bent or kinked black plunger or an extractor spring that’s gotten stuck. 

If you notice any of these signs, replacing these parts should fix your problem. Trust me, it worked for me and’ll most likely work for you too.

5. Not Returning To Battery

Let’s dive into yet another hurdle that came up during my field testing of the Glock 48: the gun not returning to battery. 

For those not in the know, “returning to battery” means that the slide fully returns to its forward position after firing, ready for the next shot. 

In my tests, the slide wouldn’t always go back into its proper place. It got stuck partway, leaving the firearm in a not-so-ready state. And let me tell you, that’s the last thing you want when you’re depending on a reliable weapon.


So, what’s the deal here? My investigation led me to a couple of possibilities. One could be improper cleaning and lubrication. 

Grime and residue could build up, causing enough friction to hinder the slide’s movement. The other could be a weak recoil spring, which we’ve discussed before. 

In both cases, thoroughly cleaning the firearm and replacing the recoil spring did wonders. However, consult the manual for specifics on properly cleaning and lubricating your Glock 48. 

If you’re not confident doing this yourself, reaching out to Glock’s customer service is smart.
