5 Most Common Glock 48 Problems And How To Fix Them

Last Update:

I’ve put the Glock 48 under my critical lens. And boy, did I have some things to discover! I’ve encountered a set of issues that left me scratching my heads, and my experiences led me to deep-dive into what was happening.

From ejecting Glock 48 problems to a slide refusing to go to battery, issues with the trigger, an excessively heavy recoil spring, and magazine hitches—these were the common Problems I’ve wrestled with while using this firearm. 

But worry not! I’ve rolled up my sleeves and managed to untangle these knots. I’ll discuss these issues in detail, share my personal experiences, and, more importantly, provide effective solutions. 

Top 5 Glock Problems & Solutions

1. Ejecting Problems

Here’s a snag I’ve noticed often: The Glock 48 fails to eject brass, regardless of the shooter, magazine, or ammunition type. 

It’s as if the extractor loses its grip on the shell, leaving me with a handful of wasted brass. I’ve noticed that the extractor seems a bit floppy, not holding its grip when the slide is rotated.


To my relief, I discovered that a defective housing/ejector assembly is often the culprit. 

Replacing this assembly seemed to resolve the issue in most cases. Another possible reason is a bent or kinked black plunger or an extractor spring stuck in the channel. If you encounter this, replacing these parts should do the trick.

2. Trigger Complications

In my exploration, I encountered a persistent issue with the trigger mechanism. To elaborate, even with an unimpeded slide cycle, I noticed that the slide wouldn’t fully charge the battery unless the trigger was let go. 

This was a peculiar observation as it disrupted the smooth operation of the firearm. Moreover, as a new round slid into position, the trigger unexpectedly snapped forward, further complicating the operation.


Upon deeper examination, I identified potential causes: misalignment of the trigger bar’s “cruciform,” requiring it to be correctly positioned in the hook of the trigger spring or a weak recoil spring assembly. 

As a fix, I suggest contacting Glock customer service for professional guidance. Modifying the connector could also be an alternative solution.

3. Complications with Glock 48’s Recoil Spring

During my tests, I also noted that the Glock 48 has some issues with its recoil spring. 

The slide would not advance fully at specific times until I relinquished control of the trigger. Additionally, there were instances where a gentle nudge on the slide’s back was necessary to advance.


These problems might originate from incorrect lubrication methods or a recoil spring lacking adequate strength. 

To diagnose this, I conducted an inspection of the Recoil Spring Assembly, adhering to Glock’s manual instructions. Should the RSA be identified as weak, a replacement could rectify the issue.

4. Magazine Disruptions

Lastly, I faced challenges with the magazine, which frequently disengaged and dropped, irrespective of the number of rounds it contained. 

Occasionally, it appeared as if an obstruction was hindering the magazine’s entry, causing it to get stuck midway.


The issue likely stems from the Glock 48’s mag being too tight for the magazines to function efficiently. 

my advice in such a situation would be to contact Glock, explain the problem, and request an upgrade to a later model. 

Also, I found it beneficial to limit the rounds inserted to no more than ten and to exercise caution when making any modifications.

5. Slide Won’t Go To Battery

Another pickle I faced was the slide refusing to advance all the way unless I released the trigger. The slide felt sticky and resistant, making it tough to regain control.


It turns out oil entering the striker channel could be the cause. 

Another possible reason could be a weak recoil spring unable to chamber ammunition properly. my fix? I fired FMJ or a box of 124-grain Winchester NATO through the Glock 48 and observed the operation. Strengthening my grip and swapping out a weak RSA proved effective.


The Glock 48 embodies a satisfactory blend of size and reliability, making it a worthy companion for duty use and serious range training. 

Yes, I faced a few snags here and there—issues with the ejection mechanism, a sticky slide, an unpredictable trigger, a heavy recoil spring, and magazine hiccups. But these issues were not insurmountable.

With the right troubleshooting steps and a bit of patience, I were able to navigate through each problem effectively. 


Are Glock 48s reliable?

Yes, Glock 48s are reliable, serving as a great balance of size and reliability, ideal for both duty use and serious range training.

Why is my Glock 48 jamming?

Your Glock 48 may be jamming due to a dirty weapon or improper extraction of the previously fired round. Occasionally, manufacturer defects can also cause jams.

Is the Glock 48 accurate?

Yes, the Glock 48 is known for its accuracy. The longer slide allows for easy sighting even under rapid fire, adding to its reputation for precision.

Is Glock 48 a good carry gun?

The Glock 48 is a good carry gun, making it a strong contender for concealed carry due to its size and reliability.

  1. Hello Michael,

    Thanks for taking the time to put together your comments on the Glock 48.

    I am new to the Glock; actually fairly new to shooting.

    I purchased my Glock with custom trigger work from very reliable company suggested by my instructor.

    During a recent training session, my Glock 48 started failing to reset the trigger. My instructor examined the gun and eventually found the cruciform was out of place. He corrected the placement; we shot about 30 rounds; it now appears to be ok.

    But it has left me not trusting it to happen again so I am researching everything I can to better understand the Glock 48 operation.

    I had previously shot approximately 150-200 rounds, mostly without problem although I did experience jamming and what appeared to be improper ejection of spent shells for about 10 shots the prior weekend. Afterwards, approximately 40 rounds were fired without incident; it was suggested by a friend I might have been experiencing a limp wrist syndrome.

    Again, thank you for taking the time to write up and post your findings.

    • Thanks for reaching out and sharing your experience with the Glock 48. It’s great to hear you’re diving into learning more about your firearm, especially after encountering a few hiccups. It’s common for custom modifications, like trigger work, to require a bit of fine-tuning. The issues you’ve faced, including the trigger reset and ejection problems, are part of the learning curve but are fixable with the right knowledge and practice.

      Limp wristing can indeed cause some of the issues you mentioned, but it’s something that improves with more shooting experience. Trust in your firearm often comes with time and familiarity, so keep practicing and researching.
