Published on:

Hey Shooters, Welcome to my Glock 45 Problems Blog.

I’m here to share some insights about my time with the Glock 45. I’ve put this gun through its paces, taking it out to the range and even incorporating it into my daily carry routine. 

Through all this hands-on experience, it became clear that the gun had its issues; I’ve stumbled upon a few issues that some of you might also face when you’re out and about with your Glock 45.

We’re looking at issues with the barrel, firing failures, ejector problems, feeding issues, and slide difficulties. 

I’ll discuss these common glitches and offer some tried-and-true solutions. You know, the kind that helps you keep your Glock 45 operating smoothly.

Quick Fixes For Glock 45 Issues

Barrel ProblemSwap original barrel or clean thoroughly after every 100 rounds.
Firing FailureClean or replace firing pin, switch to quality ammo.
Ejector IssueAvoid +P+ ammo, adjust ejector, extractor, and extractor plunger spring pressure.
Feeding IssueReplace magazine springs, use quality ammo, improve grip.
Slide IssueExperiment with different magazines and ammo, consider replacing or adjusting the slide lever release spring.

Top 5 Glock 45 Problems & Solutions

1. Barrel Problem

So, let’s dive right into the first issue I encountered with the Glock 45: the barrel challenges. After spending considerable time on the range, I noticed a glaring issue with the barrel, mainly the lack of chamber support. 

This didn’t just affect the gun’s performance; it made shooting lead bullets a real pain. The thing would jam frequently, and I even experienced some annoying Brass to Face (BTF) incidents. 

Trust me, handling the firearm started to feel like a chore rather than an enjoyable experience it should be.


Alright, on to the good stuff: the solutions. One approach I took was swapping out the original barrel for a different one with better chamber support and ammo compatibility.

This change was a game-changer, making my time at the range way more enjoyable and hassle-free. However, if you’re keen on sticking with the factory barrel, don’t sweat it; there’s a fix for you, too. 

Grab a brass brush and thoroughly clean the barrel after every hundred rounds. It’s a simple solution, but it worked wonders for me, significantly reducing jams and those pesky BTF issues.

2. Firing Failure

So, next on the list is the issue of firing failure. What’s a gun worth if it can’t fire reliably, right? 

While using the Glock 45, I ran into situations where the gun just wouldn’t fire. I’d pull the trigger, and no bang, just a whole lot of frustration. 

This is more than just a minor inconvenience; it’s a significant flaw that compromises the utility of the firearm, especially in critical situations where every shot counts.


Okay, so how did I get around this problem? First, I inspected the firing pin and found it was pretty gunked up. A good, thorough cleaning was in order, and that helped a lot. 

However, if you’ve already cleaned your firing pin and are still facing issues, you might want to consider replacing it altogether. Another trick I tried was checking the ammunition; poor-quality ammo can sometimes be the culprit. 

So, I switched to a more reputable brand, and sure enough, the firing failures went down noticeably. All in all, a clean firing pin and quality ammo turned my Glock 45 from a finicky tool into a reliable companion.

3. Ejector Issue

Alright, let’s move on to the ejector issue. You know you’ve got a problem when your Glock 45 is sending brass flying fifteen feet away! That’s not just a little hiccup; that’s a full-fledged problem right there. 

This issue persisted even when I was using weaker ammunition, which should technically reduce the distance the brass is ejected. After some digging around, it appeared the Breech Face cutout was a likely culprit.


So, how did I go about fixing this? First of all, I decided to steer clear of +P+ ammo; given the already excessive distance the brass was traveling, I didn’t need the extra oomph. 

Next, I got down to tinkering with the ejector, extractor, and extractor plunger spring pressure. Now, let me tell you, it was a learning experience! Adjusting these components is not for the faint-hearted or the inexperienced. 

If you’re new to firearms, I would advise leaving this kind of tweaking to the professionals. When I finally got the balance right, the ejection distance became much more manageable, and it felt like I had a whole new gun in my hands.

4. Feeding Issue

Next up is a truly vexing issue, the “Fail to Feed” problem. Now, there’s not much more frustrating than firing a few rounds only to find out that your Glock 45 is staring back at you with an empty chamber despite a loaded magazine. 

I mean, come on, the gun just wouldn’t feed! The suspects in this case were many: a dirty magazine, a weak spring, a deformed mag, improper insertion, or even subpar ammo. Honestly, identifying the culprit felt like a wild goose chase.


So, what worked for me? Well, first off, I replaced those magazine springs. It was a bit tedious, sure, but ultimately worth the effort. 

Next up, quality ammo. No need to break the bank, but steer clear of the bottom-of-the-barrel stuff; it makes a world of difference. Another hot tip? Make sure you’ve got a firm hold on your firearm when you’re shooting. 

This can significantly improve feeding and overall performance. These tweaks worked wonders for me, turning a frustrating issue into a distant memory. Trust me, it’s all about the little things you do right.

5. Slide Issue

Alright, let’s talk about slide issues. Here’s a funny one: my Glock 45’s slide wouldn’t lock back when the magazine was empty. 

Oddly enough, it did lock back when manually racking the slide with an empty mag. Now, that’s perplexing! 

My thoughts went to a couple of possible reasons: maybe inadvertent pressure on the slide lever release during that final shot or perhaps a mechanical issue with the slide lever release itself.


Fixing this required a bit of Sherlock Holmes-style investigation. I experimented with different 

magazines and various types of ammunition to isolate the problem. 

But, the most effective thing was to consider replacing or adjusting the slide lever release spring. Now, this was trial and error, for sure. It wasn’t an overnight fix, but patience paid off. 

After a bit of tinkering, I managed to get that slide to behave just as it should. So, if you’re encountering a similar issue, it may be time to roll up your sleeves and get to work!
