I’ve had my fair share of time with the Mossberg 835 out in the field. You could say I know this shotgun inside and out, but nothing’s perfect, right? During my time using it, I’ve stumbled upon some Mossberg 835 Problems that I believe should be addressed.

I’ve encountered issues ranging from ejection difficulties to problems with firing and cycling. Even the trigger assembly gave me a bit of a hard time. So, you’re not alone if you’ve faced these issues, too.

This article aims to guide you through these common issues and give you straightforward solutions to fix them. These are just the facts and fixes you need to get your Mossberg 835 running like a champ again. So, let’s dive in.

Top 4 Mossberg 835 Problems & Solutions

1. Ejection Issue

Ah, the ejection issue. Believe me, I’ve been there. Picture this:: you’re out in the field and take that perfect shot. 

But then, your spent shell doesn’t eject properly. It’s frustrating and could easily ruin a good day of shooting. In my experience, the ejection system can sometimes be inconsistent.

It’s not a constant issue, but it occurs just often enough to catch my attention. This problem can throw you off your game when you’re in a situation requiring rapid-fire shots.


Now, here’s the deal with the solution. After some trial and error, I found that cleaning the ejection port and replacing the ejector spring usually do the trick. 

You don’t need to be an expert to do it. Just follow the manufacturer’s guidelines on disassembling the shotgun for cleaning. Get in there with a brush and some cleaner, make it all nice and spotless, and replace the spring if needed. 

Do a test run afterward to ensure everything is in working order. It worked for me and made the shotgun more reliable, giving me peace of mind the next time I went out in the field.

2. Firing Issue

So, let’s talk about another issue that’s bothered me: firing problems. Yeah, you heard that right. I was out in the field, feeling pretty good about my setup. 

I aimed, pulled the trigger, and… nothing. A misfire is one of the worst feelings, especially when you’re relying on your shotgun to perform. 

A misfire isn’t just disappointing; it’s a safety concern. I’ve faced this issue a couple of times, and each time it happened, it was enough to make me wonder about reliability during critical moments.


Alright, enough of the problem. Let’s get to fixing it. The first thing I did was take a good look at the firing pin and chamber. Turns out, debris can accumulate there, and that can mess with your firing. 

A thorough cleaning session worked for me—just take apart the bolt assembly and give it a good cleaning. Use a soft cloth, and you might also want to use some gun oil. 

Test it with a few shots once it’s all clean and reassembled. This simple solution made a world of difference for me, making my Mossberg 835 reliable once again.

3. Cycling Problem

Okay, let’s get into another hiccup I’ve run into: cycling issues. Trust me, there’s nothing more frustrating than your shotgun jamming up when you’re cycling rounds, especially in those high-pressure moments. 

It felt like the shotgun wasn’t properly feeding the next shell into the chamber. I’ve had times where I had to manually manipulate the pump to get it to cycle. 

You don’t want to deal with that when you’re focused on your aim and your shot.


So, how did I solve this problem? Well, the first thing I did was check for obstructions. Nope, all clear. Next, I disassembled the pump action to look for worn-out parts. 

In my case, it was the action slide that was the culprit. A worn-out action slide can make the cycling process cumbersome. I replaced it and made sure to properly lubricate all moving parts. 

It’s a pretty straightforward process; just make sure you consult the owner’s manual to get it right. Afterward, I did some test shots to ensure the new parts were doing their job. And guess what? Smooth cycling restored! 

The issue was resolved, and my confidence in the Mossberg 835 was back.

4. Problem with the Trigger Assembly 

Let’s tackle the last issue on the list: the trigger assembly. In my time using the Mossberg 835, I’ve found the trigger to be less than perfect. 

Sometimes, it felt sticky, other times it felt too loose. In a couple of instances, it even affected my aim. 

Trust me, when you’re in the zone, the last thing you want is a trigger that doesn’t feel right. It disrupts your focus and can affect the outcome of your shot.


So, how did I go about solving this? I started by disassembling the trigger assembly, always making sure to follow the manufacturer’s manual. 

First, I inspected for any signs of wear and tear or debris. In my case, the issue was as simple as some gunk buildup around the trigger components.

I thoroughly cleaned it up and used some light gun-specific lubricant. If you notice worn-out parts, replace them as needed. Then, put it all back together and, of course, perform a safe test to ensure it’s functioning as it should. 

That solved the problem for me, making the trigger pull smooth and consistent, just how it should be.

Final Verdict

After spending considerable time with the Mossberg 835, I can safely say it’s a versatile and reliable shotgun for various scenarios. 

However, no firearm is without its flaws. From inconsistent ejection to firing hiccups and cycling issues, this shotgun has its share of minor drawbacks. 

Thankfully, most of these problems have straightforward solutions, which I’ve tested myself. With a bit of regular maintenance and occasional part replacements, most of these issues can be sorted out. 

Overall, despite its weaknesses, the Mossberg 835 remains a strong contender for anyone looking for a reliable shotgun, especially with the right care and adjustments.
