4 Most Common Mossberg Shockwave Problems & How To Fix

Last Update:

I’ve spent some quality time testing out the Mossberg Shockwave, and let me tell you, it’s a fascinating piece. While it has a lot to offer, there are a few areas where it could use a bit of tweaking. 

I’ve noticed some irregularities with the trigger that need attention. Next, there’s an issue with the feeding mechanism, and you can’t overlook it. Oh, and don’t get me started on the cycling action and the guide rod; those need some work, too.

The aim of this article is to shed light on these common Mossberg Shockwave Problems and, more importantly, provide you with practical solutions. 

Stick around as we delve into each problem, identify what’s causing it, and figure out how to get your Mossberg Shockwave running smoothly.

Top 4 Mossberg Shockwave Problems & Solutions

1. Trigger Problem

So, let’s get into it. First on the list is the trigger issue. I’ve noticed that sometimes the trigger feels, well, less than ideal. 

We’re talking inconsistent pull weights, where one pull might feel smooth and the next one, not so much. This inconsistency can throw off your aim, and frankly, it’s annoying when you’re trying to get the job done. 

Now, I’ve experienced this during both practice and actual use, so trust me when I say this isn’t a one-off problem. It’s something you’ll want to address right away if you own a Mossberg Shockwave.


Alright, let’s not waste time. The good news is the trigger issue can be fixed. What you’ll want to 

do is disassemble the trigger housing and give everything a thorough cleaning. 

Use a quality gun-cleaning solvent to remove any debris or fouling that might be messing with the pull. Next, lightly apply a thin layer of lubricant. 

I’ve done this myself, and it made a world of difference. After that, reassemble everything carefully and give it a test.  

You should notice an immediate improvement in consistency. But remember, always follow safety guidelines when doing any modifications or maintenance. Safety first!

2. Issue with the Feeding

Next up, let’s talk about the feeding issue. Ah, this one can be a headache. While I was out testing this firearm, more than once, I had rounds failing to feed properly into the chamber. 

It’s frustrating, to say the least. One minute, you’re nailing your shots, and the next, you’re jammed. Now, this isn’t something that happens every single time you pull the trigger, but it happens often enough to be concerning. 

Whether you’re using it for sport or self-defense, a feeding issue can be a real hindrance. You don’t want to be in a high-stakes situation only to find out your Mossberg Shockwave is not cooperating.


So how do we fix this? After a bit of trial and error, here’s what I’ve found. The root of the problem often lies with the magazine tube or the shell latch. 

Start by cleaning both of these components meticulously. Any gunk or debris can impede the rounds from feeding smoothly. Also, inspect for any worn parts, as they may need replacing. 

After you’ve done the cleaning, lightly oil the moving parts. Personally, this worked for me and eliminated the feeding issue almost entirely. 

Again, always make sure you’re following safety guidelines when performing any kind of maintenance. It’s better to be safe than sorry.

3. Problem with Cycling Action

Now, let’s get into another issue that gave me quite a bit of grief—the cycling issue. Man, this one is particularly annoying. 

I found the magazine super hard to load, and the gun just wouldn’t cycle properly, especially from the second shell onward. 

Sadly, none of that helped. After field stripping the gun a couple of times, it became clear that the elevator and possibly the cartridge stop were the culprits.


So, how did I tackle this issue? After a thorough inspection, I realized that the elevator and cartridge stop needed some serious attention. 

First off, take them out and give them a good cleaning with a gun solvent to remove any debris. Look for signs of wear and tear; if they’re worn out, you might want to consider replacing them. 

After that, lubricate the components with a light layer of oil. Make sure not to overdo it, as excess oil can attract dirt. 

Finally, reassemble and test. For me, this fixed the cycling issue, and the firearm started to function as smoothly as ever. And as always, keep safety in mind throughout this process.

4. Guide Rod Issue

Last but definitely not least, let’s talk about the guide rod issue. This was something that caught my attention pretty quickly. 

I felt some resistance and a lack of smoothness when I was cycling the action. It’s hard to ignore something like that, especially if you’re using the firearm for tasks that require quick and reliable action. 

On disassembling the Mossberg Shockwave, it was clear that the guide rod wasn’t functioning as it should. It seemed to be causing more friction than aiding the slide action, which is a no-go in any scenario.


So, what’s the fix? First things first, carefully disassemble the shotgun to access the guide rod. Inspect it closely for any signs of wear, bending, or damage. 

If you find that it’s visibly worn or damaged, replace it. If it looks okay, clean it thoroughly with a gun-specific solvent. 

Then, apply a thin layer of high-quality firearm lubricant. Once you’ve done that, reassemble your Mossberg Shockwave and test the action. This improved the slide action considerably for me. 

And don’t forget, always follow safety guidelines when working on your firearms. Better safe than regretful, right?

Final Verdict

Alright, let’s wrap things up. The Mossberg Shockwave is a mixed bag, but that’s not entirely a bad thing. Its compact design and versatility are hard to ignore. 

However, it has its share of shortcomings such as trigger inconsistencies, feeding problems, cycling issues, and the guide rod debacle. 

But here’s the thing: no firearm is perfect out of the box. The beauty of the Shockwave is that most of these issues are fixable. 

With some attention to detail, you can turn this firearm into a reliable tool. So yes, it has its drawbacks, but with a little bit of elbow grease, you’ll find it’s a piece worth having in your arsenal.
