Published on:

I’ve been spending a good amount of time testing the Beretta M9A4 in the field, and let me tell you, it’s a robust and reliable handgun. 

While I’ve mostly had a smooth experience with the M9A4, I did come across some issues you might find worth knowing about if you own this firearm or are planning to get one.

Beretta M9A4 problems include barrel issues, feeding failures, firing issues, and hammer complications. 

Now, don’t fret! In this article, I will break down each of these issues. I’ll let you know what you can do to either prevent them or fix them if you’ve already encountered them.

Top 4 Beretta M9A4 Problems & Solutions

1. Barrel Issue

So, let’s talk about the barrel issue I came across while using the Beretta M9A4. While shooting, I noticed decreased accuracy over time, which wasn’t something I expected from a firearm of this caliber. 

Initially, I thought it might be me, but after conducting more controlled tests, it was evident that the barrel was the culprit. The rifling seemed to degrade quicker than I anticipated, affecting the overall shot groupings. 

This is crucial, especially if you’re using this firearm for competitive shooting or self-defense.

Solution

Now, onto the solution. What worked for me was getting a high-quality replacement barrel. But before you rush to do that, make sure to inspect your current barrel thoroughly. 

Clean it meticulously and check for signs of abnormal wear or erosion in the rifling. If you find any, a barrel replacement becomes necessary. I got mine from a trusted manufacturer, and after installation, my shot groupings were back to being tight and accurate. 

Always remember to regularly clean and lubricate the barrel to extend its lifespan. This simple maintenance can save you a lot of headaches down the line.

2. Feeding Failure

Alright, next on the list is feeding failure. While out on the range, I had a few instances where the rounds wouldn’t feed properly into the chamber. 

Man, that can be frustrating! I was using quality ammunition, so it was pretty clear that the issue wasn’t with the rounds. Feeding failure can be alarming because it’s the kind of thing that you just can’t afford to happen in a high-stakes situation. 

I dug a little deeper and found that the magazine springs were weak, and the feed ramp was not as smooth as it should be, causing these hiccups.

Solution

Here’s what I did to fix it. First, I replaced the magazine springs with new, high-tension springs. This is a straightforward fix that ensures the rounds are pushed up reliably. Second, I took some time to polish the feed ramp. 

You’d be surprised how much a smooth feed ramp can improve the reliability of your firearm. After these tweaks, the feeding failures were completely resolved. I went through several hundred rounds without a single issue. 

So, if you encounter feeding problems, check those magazine springs and feed ramp. A little bit of maintenance goes a long way.

3. Firing Issue

Okay, let’s move on to firing failure. This one is a doozy because, well, a firearm that doesn’t fire isn’t much use to anyone. In my time with the Beretta M9A4, I experienced a couple of instances where the gun simply wouldn’t fire when the trigger was pulled. 

It’s not a great feeling, let me tell you. On inspecting, I realized that the firing pin was not striking the primer with enough force. This is a serious issue because it directly affects the firearm’s primary function: shooting.

Solution

So, what’s the fix? After taking it apart and examining the components, it became clear that the firing pin spring was worn out. Replacing it was the logical next step. 

Additionally, I also cleaned the channel where the firing pin moves; grime can accumulate there and affect its movement. After these adjustments, I went back to the range, and voila! The firearm performed flawlessly through multiple rounds of testing. 

The take-home message here is to regularly inspect and maintain your firing pin and spring. A worn-out spring can lead to a non-functioning firearm, and that’s the last thing you want.

4. Hammer Issue

Last on our list, but definitely not least, is the hammer issue. I was out in the field, squeezing off rounds, and guess what? The hammer started sticking intermittently. 

Yeah, it’s not fun. A sticky hammer can be a safety concern and could also lead to misfires or even accidental discharges. My immediate thought was that it might be a spring issue, but upon closer inspection, it seemed more complex. 

The hammer was not rotating back into its correct position consistently, causing it to stick.

Solution

So, how did I tackle this? First things first, I disassembled the hammer assembly to take a closer look. Turns out, there was some visible wear on the hammer strut, and the hammer spring appeared weak. 

The fix involved replacing these worn-out components. I used factory-certified parts for the replacement to ensure reliability. 

After putting it all back together and applying proper lubrication, the hammer functioned as smoothly as one would expect from a top-tier firearm like the Beretta M9A4.
