Mossberg 590m – Common Problems

Detachable magazine-fed guns have, over time, been produced in many countries outside the USA.

And currently, the leading American firearms makers are bringing these shotguns’ designs into production in this era.

The 590m is a magazine-fed variant of the 590-pump shotgun manufactured by Mossberg. This model is every bit as durable and trustworthy as its predecessor.

In addition, 590m have magazines that can be switched out for others with capacities of 5, 10, or 20 rounds.

Mossberg 590m Common Problems

The Mossberg 590m is made up of three separate parts, and you can remove the floorplate for the sake of maintenance.

The bodies are sizeable, but not excessively so.

However, aside from these great features, the Mossberg 590m also has some common problems, which we will discuss in this article.

Bore Obstruction

Bore obstruction is one of the common problems associated with the Mossberg 590m.

Over time, people who have used the Mossberg 590m have always complained about this problem.

However, it is essential for new and old users to be familiar with this problem.

Bore obstruction occurs in the Mossberg 590m when the trajectory of your bullet is altered.

It happens if there is dirt, debris, or any other foreign object trapped in the bore of your 590m barrel. It will cause your accuracy to suffer as a result.

To make matters worse, if there are obstructions in your bore regularly, the performance of the Mossberg 590m will degrade over time.

Timing-Related Issues

Timing issues occur in the 590m when the cylinder’s action is slightly off.

In other words, it’s not rotating into the locking position because it’s out of alignment with the barrel.

However, this is a very severe issue that everyone using the Mossberg 590m to be conversant of.

If the timing on your 590m is off, you risk having it misfire, which can be a very deadly circumstance.

To modify the timing, a professional must disassemble and repair it first. They can adjust the timing of your pistol following its caliber of it.

Firing Pins Deformities

Due to the amount of wear it sustains over time, the firing pin on the Mossberg 590m may become bowed or distorted.

If the firing pin is damaged, the primers may explode. And this may damage the Mossberg 590m and other problems with how it fires.

Failure To Feed

A cartridge would not usually feed because it does not entirely fit within the chamber.

The following are some of the reasons why the Mossberg 590m frequently experience feeding issues:

  • Damaged Magazines
  • The magazine springs do not have sufficient strength
  • Accumulation of dirt or oil within or close to the chamber
  • Improper arrangement of magazines
  • Cartridges are not in good condition

Even though you have thoroughly cleaned and oiled the gun, it is still possible to have a problem.

This issue can be remedied by removing the magazine and clearing the chamber.

You can reload your weapon and give it another try after you’ve cleaned it if you feel like it’s necessary. This kind of behavior is referred to as “riding the slide.”

You’ll discover that when you shoot your 590m, you’ll make it more difficult for the recoil spring to drive the cartridge into place since you’ll be blocking the slide.

If you are aware of this, you will likely be able to avoid problems with the feeding process.

Failure To Extract

This issue is most often caused by mistake on the user’s part. Because of this, the Mossberg 590m cannot remove the spent cartridge.

And as a result, it draws two cartridges from the magazine simultaneously.

This critical problem might rapidly deteriorate into a dangerous one if appropriate action is not taken.

The first thing you’ll want to do is take the magazine out of the Mossberg 590m. Move the slide back and forth a few times to clear the weapon’s chamber.

When doing this, make sure you maintain the muzzle of the 590m pointed in a secure position.

To guarantee that the 590m does not contain any ammunition, perform a visual inspection of the magazine well and the chamber.

After then, you can give it another shot by refreshing the page.

Common Problems With Mossberg 590m

Corrosion And Erosion

This problem occurs when proper maintenance is not given to your 590m.

If the 590m is not cleaned after each use, the residue of burned powder and then copper from the barrel can trap moisture. And this can destroy the 590m.

The sound moderator is left on the gun whenever it is not used. Because of this, corrosion may start to form in the first five or six inches of the barrel at the earliest.

Discuss the possibility of cutting and redrawing the barrel with your gunsmith, as the performance of some barrels suffers when they are shortened.

Squib Load

Squibs are rounds with insufficient powder charge to propel the bullet through the chamber and out the barrel. The bullet thus becomes lodged in the barrel.

A squib could endanger both you and your 590m. It would be best to comprehend what occurs once you press the trigger.

A squib won’t go Bang! But merely Pop! and most likely will experience less recoil than usual.

You might be able to reload and shoot another round if you don’t see a squib. However, that might seriously harm your shotgun.

Stop shooting when you notice a squib. Ensure your gun is secure, clean the action, and inspect the barrel.

Hand loads produce the most frequent squibs; however, manufactured ammo can also result in one.

With tap-rack-bang! It is impossible to clear a squib in the Mossberg 590m. Using a barrel cleaning rod and the bullet, you might be able to extract it.

If you’re doubtful, have the bullet removed by a gunsmith or by contacting the range officer.

Double-Feed Malfunction

When a round is successfully fed into the 590m magazine, the next round in the magazine will sometimes attempt to join it from behind.

As a result, the slide cannot enter the battery because a second round is jammed up against the base of the chambered cartridge.

There is no doubt that this issue is magazine-related. Magazine parts can deteriorate over time, like any other 590m part.

Most frequently, the problem is worn feed lips. However, if the slide lock is engaged, you can potentially have a frail magazine spring that lets the bullet bounce through.

Innovative shooters mark each of their magazines individually to identify which magazine is producing issues immediately. It is done in part to prevent double feeds.

Experienced shooters always carry a spare magazine as a result of this failure.

Other Common Problems Include

  • It is impossible to increase the magazine’s capacity in any way.
  • Pistol grips on the stock make it more difficult to maintain safety.
