Common Beretta PX4 Storm Subcompact Problems

1. Failure to Feed

Failure to Feed is a common issue in firearms, including the Bersa PX4 Subcompact. It is when the pistol fails to chamber a round from the magazine effectively.

This failure can result from various factors influencing the reliability and performance of your firearm. Let’s discuss the reasons and steps to rectify the problem.


1. Magazine issue: A damaged or worn-out magazine can cause the round to be misaligned or move freely, leading to a feeding failure.

How To Fix:

  • Inspect the magazine for any visible cracks or damages, and replace it with a new one if needed.
  • Check the magazine spring for proper tension; replace the spring or the entire magazine if weak.

2. Feed ramp and chamber:

A dirty, rough, or improperly polished feed ramp can lead to the round getting caught or halted during feeding.

How To Fix:

  • Clean and lubricate the feed ramp and chamber regularly.
  • If necessary, polish the feed ramp with a polishing compound carefully. (Note: Consult the manufacturer or a professional gunsmith before attempting this step, as improper polishing can lead to other issues).

3. Ammunition:

Incorrect or low-quality ammunition can affect the performance of your firearm, leading to a Failure to Feed.

How To Fix:

  • Verify and use ammunition the manufacturer recommends for your specific firearm model.
  • Opt for higher-quality ammunition from a trusted manufacturer.
  • Keep an eye on the shape of the bullet, as different profiles (e.g., round nose or hollow point) may affect the feeding process.

How To Fix:

  • Inspect the recoil spring for any damages or wear.
  • Replace the recoil spring if deemed necessary.

5. Operator Error:

Holding the pistol too lightly, commonly known as “limp-wristing,” can cause the slide not to move with enough force, leading to a Failure to Feed issue.

How To Fix:

  • Get proper grip training from a knowledgeable instructor to ensure proper shooting technique.
  • Practice firm and consistent grip to improve shooting performance.

2. Failure To Eject

The first thing to do is ensure the magazine spring is in good condition. A worn or weakened magazine spring can cause a failure to eject.

To check if this is the problem, remove the magazine from the pistol, then look at the hook on one end of the spring and ensure it is secured around its designated lip. If not, reinstall it properly.

Another possible cause for a failure to eject in your Bersa PX4 Storm Subcompact could be improperly attaching the slide stop lever.

This lever helps secure the slide when cycling ammunition rounds, so it must be correctly secured.

To check if this is an issue, open up your pistol’s casing and inspect the slide stop lever to ensure it’s properly attached.

If not, use a small screwdriver to tighten the screws holding them in place until they fit snugly.

A third potential cause could be a dirty chamber or excessive lubricant buildup inside your pistol’s barrel or chamber area.

These things can interfere with how well your ammunition feeds into and out of your weapon, failing to eject.

To address this issue, clean your gun regularly according to manufacturer guidelines and use only recommended lubricants sparingly on all moving parts of your firearm.

Finally, if none of these solutions work for you, consider taking your pistol to a certified gunsmith for more detailed repair.

They will be able to quickly diagnose any underlying issues with your Bersa PX4 Storm Subcompact and determine what needs repair or replacement, so you get back out shooting again soon!

 3. Trigger Pull Gauge Problems

The trigger pull measures the force required to pull the trigger rearward and release the hammer or striker to fire.

Trigger pull weights are usually measured in pounds (lbs). If your pistol’s trigger pulls weight is too high or too low, it can lead to safety concerns and accuracy problems.

Common causes of high or low trigger pull weights include worn or broken parts, improper assembly, improper lubrication, and user error.

To fix these issues, you must take your pistol apart according to the manufacturer’s instructions and inspect all of its components for any signs of wear or damage.

Replace any damaged parts before reassembling your gun. Ensure that all moving parts are properly lubricated with quality gun oil or grease, as the manufacturer recommends.

For proper assembly and installation of parts, always refer to the owner’s manual provided by Bersa when purchasing your weapon.

Lastly, if you have difficulty determining what might be causing your pistol’s poor trigger performance, contact a qualified gunsmith for assistance.

4. Failure To Return To Battery

A weak or worn recoil spring is one of the most common causes of the Bersa PX4 Storm Subcompact failing to return to battery.

As the recoil spring absorbs energy from each shot fired, it will eventually wear out and become too weak to be able to move the slide into the battery effectively.

Another cause could be an issue with a dirty extractor, leading to jammed rounds caused by improper extraction or ejection of spent casings.

Finally, if the pistol has been extensively used with different types of ammunition, there may be a mismatch between the slide and barrel, resulting in too much friction during cycling.

To fix this issue, first check if any visible issues such as dirt or debris, could be causing a blockage in the firing mechanism.

If none are found, replace the recoil spring with a new one specifically for your gun model or follow manufacturer guidelines for replacing them.

Next, clean out any debris from around the extractor and make sure no damage could be causing an obstruction.

Finally, ensure that all ammo being used is compatible with your gun and does not have excessive friction when entering or exiting the barrel chamber.

With these steps, you should be able to enjoy shooting your Bersa PX4 Storm Subcompact without fear of failure-to-return-to-battery problems again!

5. Jamming Problems

There are several possible causes of jamming issues in the Bersa PX4 Storm Subcompact.

The most common include feed ramps that have been improperly shaped or polished during manufacturing, magazines that are not correctly seated or have become worn over time, and old ammunition that has hardened cases or misaligned bullets.

Certain grips and aftermarket parts may cause the firearm to cycle incorrectly due to poor fitment or design flaws.

Fortunately, there are some simple steps you can take to troubleshoot and resolve any jamming issues with your Bersa PX4 Storm Subcompact:

Step 1: Inspect all components for wear and damage. Inspect all parts associated with feeding rounds into the chamber — including the magazine follower, lips, spring tension, and feed ramp — for signs of wear or damage.

Clean these components thoroughly using a good quality cleaning solution.

Pay special attention to any burrs on the feed ramp that could prevent rounds from entering smoothly into the chamber.

If necessary, use a file or stone to lightly polish away any irregularities.

Step 2: Check for correct ammunition fitment.

If you suspect improper fitment is causing your malfunctioning issues, test-fire different types of ammunition through your firearm until you find one which reliably cycles every round without any jams or stoppages.

Step 3: Adjust settings on aftermarket parts if applicable.

If you have installed any parts onto your firearms, such as target triggers, competition slides, or extended mag releases — adjust their settings accordingly so as not to interfere with proper cycling motion once fired.

Occasionally some aftermarket parts may require minor adjustments before they work properly without causing jams or malfunctions when shooting live rounds.

6. Slide Stuck

One of the primary reasons for a slide stuck issue in a Bersa PX4 Storm Subcompact is the presence of dirt, debris, or fouling in the internal parts of the firearm. Excessive carbon build-up from shooting and inadequate cleaning and maintenance can lead to a jammed slide.

Follow these steps to resolve the slide stuck issue in your Bersa PX4 Storm Subcompact:

1. First and foremost, make sure that your firearm is unloaded. Remove the magazine and double-check the chamber to ensure it is empty, taking all necessary safety precautions.

2. Apply a small amount of gun cleaning solvent to a soft, lint-free cloth or gun cleaning patch. You may use a soft toothbrush or a nylon brush to rub the gun cleaning solvent into the slide rails and other areas with visible fouling.

3. Once you have applied the solvent, let it sit for a few minutes. This will allow time for the solvent to penetrate and break down the fouling.

4. Begin gently scrubbing the slide rails, slide grooves, and other internal parts with a soft toothbrush or nylon brush. Pay close attention to the surfaces where the slide meets the frame, as dirt and grime can accumulate in these areas and cause the slide to stick.

5. Using a lint-free cloth or gun cleaning patch, wipe away the loose dirt and fouling from the slide rails, grooves, and other internal parts.

6. After thoroughly cleaning the inner parts of your firearm, apply a thin layer of gun lubricant to the slide rails and slide grooves. Make sure to use a lubricant designed specifically for firearms, as common household oils can attract dirt and grime, leading to more issues in the future.

7. Reassemble your firearm by carefully aligning the slide with the frame and slide rails. You may need to use a small amount of pressure to move it back and forth to ensure smooth operation.

8. Perform a function check to ensure the slide works correctly. This includes cycling the slide several times, engaging the safeties, and dry firing (while ensuring the firearm is unloaded and pointed in a safe direction).

7. Poor Accuracy

One common cause of poor accuracy with the Bersa PX4 Storm Subcompact is improper form and grip.

Consistency is key to good accuracy, so you must develop a habit of proper form and grip every time you shoot.

If possible, seek out professional training or practice with experienced shooters to learn the correct techniques for gripping and shooting with a handgun like the Bersa PX4 Storm Subcompact.

With practice and repetition, you should eventually be able to develop consistent habits that will help improve accuracy.

Another potential cause of inaccuracy is inadequate ammunition selection.

Different types of ammunition can affect handguns like the PX4 Storm Subcompact, so selecting ammunition suitable for your particular firearm is important.

Pay attention to velocity ratings and bullet design; selecting high-velocity rounds or hollow-point rounds may give you better accuracy than standard full metal jacket ammo.

Additionally, ensure you’re using quality ammunition produced by reputable manufacturers; if possible, test out multiple kinds of ammo at the range before committing to any type for serious practice or competition use.

Finally, even if your form and grip are correct and you have selected suitable ammo for your firearm, other external factors, such as too much recoil or an improperly adjusted sight can lead to poor accuracy with a handgun like the Bersa PX4 Storm Subcompact.

If recoil is an issue, try shooting with a lighter load or switching out components such as guide rods or buffers to reduce felt recoil without sacrificing muzzle velocity too much; likewise, make sure that the sights on your pistol are properly adjusted to ensure accurate shot placement at any distance.
