1. Cycling Issue:

The Beretta A400 Xplor has had multiple complaints from users about the cycling issues that come with the gun itself.

The A400 Xplor Action will often not cycle standard factory loads. Even after the gun has been broken in properly for a prolonged period.


Almost all cycling issues that the Beretta A400 Xplor Action faces, can be solved by following a simple cleaning method.

Every A400 Xplor model has two gas ports. The first one, which is drilled, oftentimes does not meet exact quality standards.

To fix the issue you have to clean up this port. Find a drill bit with the exact same size as the existing hole on the A400 Xplor Action. You have to use the said drill bit to clean up the gas port.

Do not use a drill. Only the drill bit. And operate it with your hands slowly. Only a few metal flakes should be removed.

2. Ejector Displacement:

The ejector has a specific channel on which it rides back and forth the gun. However, with prolonged usage, the ejector may work out of its dedicated channel.

The ejectors on the A400 Xplor are staked in from the factory. But with time, the metal might slowly get loose from its dedicated slot.


The solution is to simply re-stake the ejector back into its guiding channel. And if there is any wear on the ejector, you could also replace it.

Replacement ejectors (Fig 1) for the Beretta A400 Xplor Action are easily found online. You could either replace it yourself or consult a qualified gunsmith for the task.

A qualified gunsmith can also assist you with the re-staking of your old ejector pin if needed.

3. Jamming Issues:

Sometimes the Beretta A400 Xplor Action faces problems with the shells jamming inside the gun.

This can be due to several reasons. One must hold the gun with appropriate strength so that much of the recoil cannot be absorbed by the shooter.

Or it could be due to the ammo type. And finally, it could be due to a dirty gun.


The first step is to see if changing the stance of the shooter fixes the problem or not. If the issue persists, you may try different ammo to remedy the issue.

And finally, properly clean the gun and lubricate it as intended. This should hopefully remedy any issue regarding the shells jamming while shooting the gun.

4. Extractor Damaging Chamber Lip:

As stated previously, the Beretta A400 Xplor Action, does not always meet the quality control standards of many users.

One such issue is the extractor damaging the chamber lip (Fig 2) with prolonged usage. The extractor slowly chips away a bit of material where it contacts the lip of the chamber.


The chamber lip material is quite soft to withstand that sharp angle of the extractor constantly rotating against its surface.

With more wear, the bolt head gets harder to rotate. It also grabs onto the shell rim and hence the harder it is for the bolt head to rotate and lock into the barrel.

The issue may be fixed by removing the extractor and grinding a nice radius on the bottom edge of the extractor. This will slightly grind off the valley that forms on the chamber lip.

Then you may proceed to polish both surfaces with a polishing compound of your choice.

However, if that extractor should happen to wear out, it can be easily replaced. Replacing the extractor is significantly easier than replacing the barrel.

5. Ejection Problems:

The Beretta A400 Xplor Actin often faces ejection issues due to several reasons. Such as an obstructed gas port or low-quality ammo. Cheaper shells with steel bases are most likely to cause this issue.


It is always advised to keep the gas port clean. As it can introduce several malfunctions into the gun.

Some ammo that has good compatibility with the Beretta A400 Xplor Action are Remington Gun Clubs, Estate SS, AA, and the Academy Monarchs.

And it might also be due to not properly breaking in the gun. Hence it is good practice to shoot the gun for a prolonged period to break it in, to ensure intended functionality.
