Glock 34 Problems You Must Know

Last Update:

Hey Shooters! Welcome to my Glock 34 Problems Blog.

I recently spent some time at the range, putting the Glock 34 through its paces. 

Let me tell you, I had high hopes for this bad boy. I mean, it’s a Glock, right? Renowned for its reliability and performance. But alas, even the best aren’t perfect. 

While shooting, I faced issues ranging from feeding problems to ejection failures. Oh, don’t get me started on the slide lock and firing issues. And the grip, well, it had its own set of problems, too. 

So do not worry; the goal here is to give you the lowdown on these common Glock 34 Problems and offer some straightforward solutions. 

Quick Table For Glock 34 Problems

Here’s the quick reference table for the top 5 Glock 34 problems and their solutions:

Feeding ProblemTry different ammunition, clean the feed ramp, replace recoil springs or switch barrels if needed.
Ejection FailureSwitch to factory ball rounds, clean and lube regularly, consider sending it for professional service.
Slide Lock IssueCheck for misaligned coil spring in lever’s center, replace extended slide stop with a regular one.
Firing FailureRemove any lubricant from the firing pin passage, strip the gun to inspect parts for wear or damage.
Grip ProblemAdd grip tape to handle, experiment with different backstraps.

Top 5 Glock 34 Problems & Solutions

1. Feeding Problem

So, there I was at the range, all set to get some good trigger time with my Glock 34. Everything seemed fine until I ran into this annoying “failure to feed” issue. 

About every twentieth round or so wouldn’t feed, leaving me scratching my head. I thought, “Could it be the PPU ammo I’m using?” But the problem wasn’t limited to that. 

My mind raced through other possibilities: maybe it’s the magazines, or could it be the feed ramp or slide causing the hang-up? Trust me, it’s frustrating when you’re all set for some smooth shooting, and then you hit a snag like this.


After a good old trial and error session, I cracked the code. First, I switched up the ammunition. I tried some 124-grain round-nose range cartridges, and voila, they fed like a charm. 

But wait, there’s more. I also gave the feed ramp a good cleaning, making sure to remove any burs that might cause issues. 

And let me tell you, that made a significant difference. Last but not least, if you’re still facing problems, consider switching barrels or replacing the recoil springs. 

In my case, these changes rounded out the troubleshooting process, and now my Glock 34 is back to its reliable self.

2. Ejection Failure

Alright, let’s talk about another hiccup I encountered: “failure to eject.” Now, I noticed this issue more often when I was using 115-grain range ammo. 

Basically, every so often, the Glock 34 decided it didn’t want to eject a round, causing a jam. It’s super frustrating, especially when you’re in the zone, and suddenly, your gun’s not playing nice. 

I had a few suspects in mind that could be causing this. Was it the optics I had on? Maybe the increased mass of the slide? Could it be the light ammo loads or even underpowered ammunition? Lots of factors were at play here.


So, how did I solve this? First off, I switched to using factory ball rounds, specifically the W-W white box ball ammo. 

That seemed to do the trick for the most part. However, if the problem keeps bugging you, don’t hesitate to send your Glock 34 back to the manufacturer for a quick service. 

They know their stuff and fixed mine up well as new. Regular cleaning and lube also made a world of difference. 

And hey, if you really want to keep that ejection performance smooth, you might want to think twice before adding any optics. Just a tip from someone who’s been there, done that.

3. Slide Lock Issue

Well, well, well, just when you think you’ve seen it all, another issue pops up, right? After putting about 600 rounds through my Glock 34, the slide started having a mind of its own. 

Specifically, the slide locked back when it definitely wasn’t supposed to, like when the mag was empty. I heard a few theories about what could be causing this, like a misaligned coil spring or an extended slide stop. 

And let’s be honest, when you’re in the middle of shooting, the last thing you want to deal with is a finicky slide.


It’s time to roll up the sleeves and figure this out. First, I made sure that the small coil spring in the lever’s center was straight. 

A misalignment here can mess things up, so make sure to check that. Then I swapped the extended slide stop for a regular one, and guess what? Problem solved. 

Oh, and never underestimate the power of good-quality ammo. A better-grade bullet can make your day a whole lot easier. 

And, as always, a clean, well-oiled gun is a happy gun. After taking these steps, my Glock 34’s slide was back to behaving itself.

4. Firing Failure

Just when I thought I’d seen it all, my Glock 34 threw me another curveball: a “failure to fire.” This one was pretty noticeable with certain ammo, like the 147gr. Ranger and the 115gr. White Box. There’s not much that can be as frustrating as pulling the trigger and not hearing that bang you’re expecting.

 My hunch was that this might have something to do with the striker assembly, specifically some improper lubrication in the firing pin passage.


Here’s how I went about fixing it: First, I ensured the firing pin passage was completely free from any lubricant or oil. You’d be surprised how a little residue can throw the whole system off. 

To be thorough, I did a detailed strip of the gun to see if any parts were unusually worn or non-standard. Having a second Glock for comparison was a lifesaver in this regard. 

Going through these steps together made a big difference. Now, the “failure to fire” issue has been significantly reduced, and I’ve got my trusty Glock 34 back in reliable form.

5. Grip Problem

Alright, so here’s something you might not see coming: grip issues. Now, I love my Glock 34, but the grip wasn’t giving me the comfy, secure feel that I’d like when I’m firing. 

It’s not just a cosmetic thing; a bad grip can really mess with your aim and overall shooting experience. You start to feel it, especially after you’ve been out in the field for a while, and believe me, it’s annoying.


So, how did I fix it? First off, I tried adding some grip tape to the handle. 

This is a straightforward fix that can drastically improve your hold. I also experimented with different backstraps that Glock offers. 

4 Alternatives to Glock 34

When it comes to selecting a firearm, options are always good to have. Although the Glock 34 is a fantastic choice for many reasons, it’s worth considering other guns that might better suit your needs or preferences. Let’s dig into some worthy alternatives.

1. Smith & Wesson M&P9 M2.0

This is a solid option for those who are looking for a 9mm. Similar to the Glock, the M&P9 offers a polymer frame but differentiates itself with an 18-degree grip angle for a natural point of aim. It’s also known for having a comfortable grip texture.

2. CZ 75 SP-01

The CZ 75 SP-01 is an all-steel gun, which gives it added weight for better recoil management. Its accuracy is superb, and its grip ergonomics are praised by many. It’s a great option for competition shooting, much like the Glock 34.

3. Beretta 92FS

This Italian-designed firearm is a classic. It has seen use in various military forces and police units worldwide. The 92FS offers a high magazine capacity and is noted for its durability.

4. Sig Sauer P320 XFive Legion

This gun comes with a lot of the high-end features you’d usually pay extra for, like an improved trigger, enhanced ergonomics, and sights optimized for competition. The P320 XFive Legion also features a tungsten-infused grip for added weight and recoil control.

Final Verdict

Alright, folks, let’s wrap this up. While the Glock 34 has its share of problems, it’s still a solid firearm. We’re talking about feeding issues, ejection hiccups, slide lock anomalies, firing failures, and grip concerns. 

But, as I’ve shared, there are straightforward solutions for all of these. Whether it’s changing the ammo type, getting some quality cleaning done, or even replacing certain parts, these problems are fixable. 

So, when you invest time in troubleshooting, you can trust your Glock 34 to be as reliable as they come. You’ll be left with a firearm that runs like a well-oiled machine. 


Is Glock 34 good for home defense?

Yes, the Glock 34 in 9mm or the G35 in .40 S&W are both suitable for home defense and recreational shooting. The G35 can also be converted to 9mm with a new barrel and adjusted sights.

Is Glock 34 good for carry?

Carrying the Glock 34 IWB (Inside the Waistband) is possible, but its longer muzzle may not be comfortable for everyone. A Glock 17 might be a more manageable option for concealed carry.

How far can a Glock 34 shoot accurately?

In my experience, the Gen 5 Glock 34 models can shoot groups of two inches or better at 25 yards.

Is Glock 34 more accurate than Glock 17?

Yes, the longer slide of the Glock 34 provides a longer sight radius, which generally allows for more precise sight alignment and better accuracy, especially at longer distances.
