Mossberg MC2SC Problems With Their Practical Solutions:

1. Not Returning to Battery:

The issue can disrupt the shooting flow, mainly when quick and successive shots are necessary.

It often results in a delay between shots, affecting the performance and reliability of the firearm.

These factors contribute to this problem:

  • Faulty ammunition
  • A dirty slide
  • Improper lubrication
  • Worn or damaged slide rails


The first step to tackling this issue is to ensure the slide and extractor pin are sorted out.

Sometimes, a simple cleaning can remove any gunk that may have accumulated, hindering the slide’s movement. Switching to quality ammunition can also help alleviate this problem.

For a quick fix in a shooting situation, giving the slide a firm bump forward can sometimes move it back into place.

However, thoroughly cleaning the firearm and ensuring the extractor pin is a more consistent solution which will help ensure the slide returns to the battery smoothly.

2. Failure To Feed:

Feeding issues can be frustrating for semi-automatic firearms owners, and they’re no exception with the Mossberg MC2SC.

Despite its reliable shooting reputation, feeding hiccups can disrupt the experience. As an owner, I’ve encountered these firsthand.

Jams and failure to properly chamber rounds are not uncommon, especially with older magazines or certain rounds. Given the firearm’s apparent reliability, this can be unexpected.


To address failure to feed requires some detective work to get to the root of the issue. While it can be complicated, several steps can help resolve it:

  • Examine the magazine’s spring for wear or damage, and replace if necessary.
  • Check the extractor for proper function, and consult a qualified gunsmith if needed.
  • Clean the chamber to remove any gunk affecting the feed.
  • Maintain a firm grip on the firearm and make adjustments if necessary.

In my experience, a spring replacement and chamber cleaning effectively resolved feeding issues with my Mossberg MC2SC. With these adjustments the problem vanishes, as it does in Remington 1911 R1 problems.

3. Slide Problem: 

First, addressing slide issues is crucial for smoothly operating your semi-automatic firearm like the Mossberg MC2SC. Any hang-ups can be a deal-breaker during running drills or practicing for quick reloads.

If you encounter a slide issue, don’t dismiss it as a one-time thing. Pay attention to ensure it doesn’t become a recurring problem that affects your shooting experience.


The good news about slide issues is that they are often straightforward to resolve with proper maintenance. If you encounter a hiccup with the slide there are steps you can take to ensure it operates smoothly:

  • Start by thoroughly cleaning the slide and rails and removing dirt or debris.
  • Proper lubrication of the components can also help.
  • If the problem persists or you’re unsure, consider seeking assistance from a qualified gunsmith to ensure your firearm is safe and reliable for the range.

4. Trigger Sear Problem:

Last but not least, if you’re familiar with firearms, you know that the trigger sear holds the hammer or striker in place until you pull the trigger.

Over time, you may have noticed inconsistent or smooth trigger pulls, which can be a noticeable hitch when you’re about to fire a shot.

When your trigger sear isn’t functioning correctly, it can lead to an unreliable shooting experience.


If you have a specific issue with the trigger sear, consult a certified gunsmith for a manual inspection and a tailored solution.

They can address the issue with professional servicing, including cleaning, repositioning, or filing down surfaces for smoother operation.

After servicing, conduct multiple test runs to ensure consistent and reliable trigger pulls. This will resolve the problem and instill confidence in your firearm’s reliability.

My Friends Feedback:

My friends who own the MC2SC have provided valuable insights into the issues they’ve encountered. One common problem is failure to feed when using different ammo types. They’ve experienced instances where the slide fails to catch the magazine properly, especially with the 11th and 14th mags.

Some have tried Remington 124 gr brass FMJ rounds but have encountered consistent malfunctions. Despite being an EDC handgun, they hesitate to recommend it due to these malfunctions.

The Mossberg MC2SC boasts features like metal sights, front and rear cocking serrations, and a flat trigger. However, some have encountered issues with loose rounds and have had to use blue Loctite for a secure fit.

Despite its flaws, its ergonomic safety and rounded slide-top design have received praise, although there are common complaints about the grip angle.

Comparisons with other subcompact 9mm handguns, such as the Kahr CW9, Springfield Hellcat, and M&P Shield 2.0, reveal that while the MC2SC offers features like optics readiness and drop-free mags, it may lack the refinement of its competitors.

Some users have noted issues with barrel length, recoil, and grip, preferring models with a slimmer profile for concealed carry.

Despite these drawbacks, Mossberg’s strides in the handgun market, particularly with its MC2SC offering, are recognized.
