Glock 45: Problems with Practical Solutions

1. Fail to Feed (FTF):

First of all, our big concern is failure to feed. The Glock 45 has occasionally refused to feed rounds properly. It leads to a subpar performance.

The root cause of dirty or improperly inserted ammo proved challenging to pinpoint.

This ongoing quest for solutions underscores the imperative need for a comprehensive understanding of the Glock 45’s intricacies.


Let’s seek a solution. A long way has been traveled in understanding the importance of a well-maintained and properly functioning magazine.

Whether it’s a subtle spring issue or a task as simple as ensuring a clear path for the rounds, these seemingly small fixes go a long way.

The white box of ammunition proved to be a valuable partner.

2. Barrel Challenges:

Next is the barrel issue. The chamber’s support for several bullets brings forth frequent and cumbersome brass-to-face (BTF) issues. It makes the gun’s handling more cumbersome.

Exploring the intricacies of the Glock 45’s barrel reveals significant and ongoing challenges and frequent headaches during continued handling.

Addressing these issues becomes imperative for ensuring smoother and more efficient handling of the Glock 45.


The solution requires more than routine cleaning; it necessitates a comprehensive solution.

Opting for enhanced compatibility between different ammunition types and factory barrels, we replace the stock barrel with an aftermarket one.

It provides better support and efficacy after each round is fired.

3. Ejector Issue:

Our next frustration is the ejector issue.

I’ve researched the possible causes behind erratic ejection patterns, especially when dealing with weaker ammunition.

One likely culprit pointed to the ejector, which seemed to struggle with brass expulsion at distances beyond the usual tossed brass.

This prompted me to delve deeper into the intricacies of the breath-face cutout and its role in ensuring consistent ejection.


Addressing this required a learning curve, considering the pressure curve with +P+ ammo. Owners implemented tweaks to both the extractor and ejector.

Tampering with the spring and plunger proved crucial in refining the ejection process.

Embracing this learning curve is recommended for Glock 45 owners.

Understanding these nuances not only builds trust in the firearm but also empowers users to optimize their weapon’s performance effectively.

4. Slide Complications:

Do you know? Owners encountered instances where the slide failed to rack back after the final round. They explored the possibility of a mechanical issue with the release lever.

Deliberately emptying the magazine revealed an interesting scenario: the slide failed to lock back.

This led them to hypothesize that an inadvertent release during the final round could be the cause.


Tackling slide complications demands a strategic approach. It involves adjustments to the release lever and experimenting with various spring varieties.

Careful adjustment and, if needed, replacement of magazines are essential for ensuring a smooth slide operation.

5. Difficulties with the Trigger:

Over time, owners experienced challenges with trigger control and noticed additional effort needed to depress the striker pin fully.

This led to misalignment issues, where the striker pin failed to seat properly.

Upon investigation, I discovered that the trigger channel had aged, necessitating more effort than ideal to manipulate the trigger.

This aging process is common in firearms.


The solution involves carefully removing all parts of the trigger assembly and then reinstalling them into their recesses.

However, I suggest considering an alternative solution, such as replacing the connector or improving the striker.

In one instance, I found that applying grease to the spring and carefully reinstalling all parts effectively improved the situation.

6. Jamming Problems:

Jamming problems with the Glock 45 can be a frustrating ordeal. A common cause of jams is a dirty or worn-out extractor. It is a crucial part of the firearm that removes spent casings from the chamber after firing.

Poor maintenance over time can lead to debris buildup.

Additionally, an improper grip on the gun can lead to misfires or rounds failing to eject properly.

Magazine issues, such as dirty or damaged magazines, can also prevent rounds from feeding properly.

Furthermore, ammunition issues, such as using damaged or wrong-caliber ammunition, can also cause firearm malfunctions.

Lastly, recoil spring issues, such as worn-out or damaged recoil springs, can affect the cycling of the slide, leading to jams.


To fight this, it’s crucial to clean and regularly inspect the extractor. It ensures it’s in optimal condition.

If necessary, replace worn-out or damaged parts with the right type of extractor to prevent future issues.

Additionally, proper lubrication of the recoil spring and magazine can significantly contribute to smoother operation. It reduces the likelihood of jams.

7. Stove piping:

So, encountering stove piping becomes a frustrating and potentially dangerous issue for shooters.

Here, a spent casing fails to fully eject. Its sticking up from the pistol’s chamber demands a strategic approach.


Start by ensuring you use high-quality, properly sized ammunition that provides ample force to cycle the slide smoothly.

Additionally, thoroughly clean your pistol, paying special attention to the chamber and extractor.

Remove any debris or fouling, and inspect the ejector for any signs of wear or damage.

If necessary, potentially replace the ejector.

By taking these steps, you can avoid the frustration and potential safety hazards associated with stove piping.

My Final Conclusion:

As a Glock 45 lover, I’ve researched a fair share of complications with this firearm.

While it may disappoint at times with glitches and minor issues, its overall reliability and sturdy build have proven invaluable.

From feed problems to ejector concerns, each challenge presented an opportunity to experiment and uncover solutions.

It’s essential to approach these common problems with patience and elbow grease, knowing that with perseverance, even the most stubborn issues can be sorted out.

For Glock 45 enthusiasts, it’s crucial to recognize that this firearm may not be invincible. Its potential issues are part of the broader discussion among Glock users.

By acknowledging stovepipes, failures to extract, and slide lock issues, we can collectively strive to enhance our experience with this iconic pistol.

My Friends Feedback:

Some of my friends who own Glock 45s have had some issues with them.

One friend with a Gen 5 G19 had trouble with the gun not ejecting brass properly, which led to jams and the gun not feeding properly.

They tried adding good-quality optics like the Holosun 407 and the Streamlight TLR-7A but still had problems like the batteries dying and rounds getting stuck in the gun.

Another friend who owns a Glock 45 had problems with the Optic Ready version of the gun.

They had issues with a screw on the right side of the gun, which caused problems with the gun feeding properly and going back into the battery after firing.

My brother-in-law bought a Glock 45 from Academy Sports and had issues with it just a month later.

The gun wasn’t ejecting spent cartridges properly and was having trouble feeding new rounds during shooting.

Even after sending it back to the manufacturer and trying different magazines, recoil springs, and fixing a tight chamber, the gun still wasn’t reliable.

When comparing it to an older Gen 1 Glock 17 that had similar issues when firing certain types of ammo, it made us wonder if Glock’s reputation for reliability is always true.

These stories show how important it is to deal with problems quickly, use warranties, and understand that even well-known guns can have issues sometimes.
