2. Failure to Eject 

The primary cause of the Failure to Eject in Bersa Thunder 380 is due to a weak magazine spring or an out-of-spec magazine.

This means the magazine spring is either too worn out or too stiff, thus resulting in a jam when the gun is fired. A faulty extractor or out-of-spec chamber dimensions can also cause the issue.

To fix the Failure to Eject issue in your Bersa Thunder 380, there are a few steps that you need to take.

Firstly, ensure your magazine springs are in good condition and aren’t excessively worn out or damaged. Secondly, inspect your extractor for any damage or wear and tear and replace it if necessary.

Lastly, check the chamber dimensions for accuracy according to factory specifications and make any necessary adjustments.

3. Failure to Feed

A Failure to Feed (FTF) issue in the Bersa Thunder 380 typically occurs when the pistol’s slide fails to strip a round from the magazine and properly seat it in the chamber.

This can be due to several factors, including damaged or dirty magazines, poor ammunition, improper grip or stance, and even general wear and tear in the firearm.

To fix Failure to Feed issues in your Bersa Thunder 380, follow these steps:

1. Thoroughly inspect the magazine:

The magazine is the most likely culprit for FTF issues. Check the magazine lips for deformities, cracks, or damage that may prevent the smooth passage of rounds.

Ensure the magazine spring is free of rust or debris and provides adequate tension. Replace any damaged components or consider purchasing a new, quality magazine.

2. Clean and lubricate your firearm:

Regular maintenance is crucial for the longevity and performance of your Bersa Thunder 380. Field strip the pistol and thoroughly clean any debris or fouling from the barrel, feed ramp, and other moving parts.

Apply a light coat of lubricant to the slide, rails, and other metal surfaces in contact with each other. Reassemble the pistol and function check to ensure proper operation.

3. Evaluate your ammunition:

Poor quality or improperly stored ammunition can lead to FTF issues. Inspect your rounds for dents, corrosion, and differences in overall length.

Stick to using factory-loaded, brass-cased ammunition that meets the manufacturer’s specified power factor for the best results.

4. Adjust your grip and stance:

A loose grip or improper body positioning can result in ‘limp wristing,’ where the inertia lost during recoil effectively robs the pistol’s slide of its momentum.

This can lead to FTF issues. Maintain a firm grip on the pistol, and adopt a more aggressive stance. Engage your arms and upper body to absorb the recoil while allowing the slide to cycle fully.

5. Inspect the firearm for wear and tear:

Finally, if these steps do not resolve the FTF issue, internal components may have experienced excessive wear or damage.

Check the extractor, ejector, recoil spring, and guide rod for any visible signs of wear. If necessary, consult a professional gunsmith for further diagnosis and repair.

4. Failure To Fire

Failure to fire, also known as a “misfire” or a “click but no boom”, occurs when the gun fails to discharge a round despite the trigger being pulled and the hammer falls.

There are several possible reasons for this issue in Bersa Thunder 380, including ammunition problems, a dirty firearm, or malfunctioning components. Let’s examine each cause and its respective solutions.

1. Ammunition Problems:

The most common reason for a failure to fire is faulty or old ammunition. Over time, the primer compound in the ammunition can deteriorate, preventing the round from discharging.

How To Fix:

First and foremost, always use high-quality and fresh ammunition. Check the expiration date on the packaging and discard any ammunition that is excessively old or shows signs of corrosion. If you’ve had a misfire, wait for at least 30 seconds before ejecting the faulty round to ensure it’s not a hangfire (delayed ignition).

2. Dirty Firearm:

A dirty or poorly lubricated firearm can cause a failure to fire. The buildup of fouling, debris, or excess lubrication can prevent the firing pin from striking the primer with enough force to ignite the fuel.

How To Fix:

Regularly clean and maintain your Bersa Thunder 380. Disassemble the firearm, remove any fouling or debris, and properly lubricate all moving parts.

Pay particular attention to the firing pin and its channel, ensuring that they are free from excessive dirt or grease. Reassemble the gun, making sure all components are in their correct positions.

3. Malfunctioning Components:

A broken firing pin or a malfunctioning trigger mechanism can also cause a failure to fire.

How To Fix:

Inspect the firing pin for any visible damage, such as a fracture or excessive wear. If there is apparent damage or malfunction, replace the faulty part.

Similarly, check the trigger mechanism for any broken or worn components that might require replacement.

4. Weak Hammer Spring:

A weak or fatigued hammer spring may not provide enough energy to drive the firing pin into the primer with sufficient force to ignite the propellant.

How To Fix:

Inspect the hammer spring for any signs of weakness, such as deformation, rust, or fatigue. If the spring is suspect, replace it with a new one.

By following the steps mentioned above and addressing the specific issue causing the failure to fire, you can ensure that your Bersa Thunder 380 remains reliable.

5. Safety Problems

The most notable safety issue with the Bersa Thunder 380 is accidental discharges. This occurs when an operator mishandles or improperly stores their firearm, leading to an unexpected shot being fired unintentionally.

The most common causes of accidental discharge are improper finger placement on the trigger and not ensuring that a round is not in the chamber.

To address this, operators should ensure their fingers are nowhere near the trigger until they are ready to shoot.

Secondly, it is important to visually inspect each round while loading magazines and checking each chamber prior to firing.

Lastly, if an operator feels uncertain about safely handling a gun, they should immediately consult a qualified instructor before continuing.

Another risk posed by the Bersa Thunder 380 is its tendency for jamming and failure to feed issues when loaded with certain types of ammunition.

This can cause malfunctions, leading to serious injury or even death if left unchecked.

To reduce these risks, operators should use only direct factory-approved ammunition for their particular pistol model and avoid aftermarket counterparts that may not have been tested for compatibility and reliability.

Additionally, regular cleaning and maintenance will help ensure that your firearm remains functioning properly, as well as inspecting all components using it, such as springs, extractors etc..

6. Trigger Problems

One of the primary reasons for trigger problems in the Bersa Thunder 380 is due to an issue with the trigger return spring.

After firing every shot, this spring helps move the trigger back into its starting position.

When this spring becomes weak or broken, it won’t be able to do its job effectively.

As a result, the owner may experience sticking or slipping triggers as well as short or long pulls – all of which can lead to misfires or jams.

In addition to a worn-out trigger return spring, certain parts within the gun can wear down over time and cause similar issues.

For example, if the hammer strut is too worn, it can interfere with the reset action of the trigger; similarly, if there is excessive wear on either side of the sear notch where it engages with the hammer hooks, it can cause misfires and other problems.

Fortunately, all of these potential issues are relatively easy to diagnose and resolve with some basic maintenance steps.

First, you should visually inspect all components inside your Bersa Thunder 380 to check for any wear or damage.

In particular, pay close attention to those mentioned above (i.e., trigger return spring, hammer strut and sear notch).

You should also ensure that none of these parts is excessively loose or tight in their respective spots within the frame assembly; if they are, they may need to be adjusted accordingly so that they function properly again.

Finally, after inspecting each component carefully, consider replacing any part that appears excessively worn out or damaged beyond repair – such as broken springs or badly damaged hammers – with new replacement ones from your local gun store; doing so should help restore your gun’s functionality to normal levels again without further troubleshooting is necessary.

7. Hammer Problems

The first step in fixing hammer issues is to understand what might be causing them in the first place.

Generally, these malfunctions are caused by poor-quality ammunition or parts out of tolerance.

Poorly constructed rounds or components can cause light primer strikes and failure-to-fire problems, leading to hammer failure.

Weak springs or worn firing pins may also be the culprit behind hammer misfiring and other malfunctions.

To ensure the proper functioning of your Thunder 380’s hammer system, it’s important to use only high-quality ammunition and components.

Always inspect all rounds before loading your firearm and look for any signs of damage or defects in both the cartridge case and primer.

Additionally, you should regularly check all springs associated with the firing pin system for wear – especially after extended storage periods. Finally, clean and lubricate your firearm regularly for optimal performance.

8. Jamming Problems

One of the leading causes of jamming problems in the Bersa Thunder 380 is the use of low-quality or incorrect ammunition.

The Bersa 380 is specifically designed to use factory-made, brass-cased FMJ (Full Metal Jacket) rounds.

However, using cheap or reloaded ammunition, steel-cased rounds, or hollow point bullets can lead to feeding problems or jams.

To avoid this, always use high-quality, factory-produced ammunition recommended by the manufacturer.

Another common issue is a dirty or improperly lubricated firearm. Over time and use, gunpowder residue and dirt can build up inside the gun, affecting its performance and causing jams.

Insufficient lubrication can create friction between moving parts, leading to jamming issues. Follow these steps to clean and lubricate your Bersa Thunder 380 to resolve these issues:

1. Ensure the firearm is unloaded: Double-check that there is no round in the chamber and remove the magazine.
2. Disassemble the firearm: Follow the manufacturer’s instructions to field strip the gun into its main components (slide, barrel, recoil spring, and frame).
3. Clean the barrel: Using a cleaning rod with a properly sized bore brush and cleaning solvent, scrub the inside of the barrel to remove the buildup of gunpowder residue and dirt. Then, use a clean cloth or patch to remove the loosened debris.
4. Clean the other components: With a clean cloth, toothbrush, or nylon brush, gently scrub the slide, frame, and other parts to remove dirt, debris, and residue. Pay attention to the feed ramp and chamber, which are critical for proper functioning.
5. Lubricate the firearm: Apply a quality gun lubricant on the slide rails, barrel, and other moving parts, as the manufacturer recommends. Ensure you don’t over-lubricate, which can attract more dirt and debris.
6. Reassemble the firearm: Follow the manufacturer’s instructions to assemble the gun and perform a function check to ensure everything is in order and working properly.

Lastly, weak or worn magazine springs can also cause jams in your Bersa Thunder 380.

The springs push the rounds into position for feeding into the chamber, and if they are weak or worn, it can cause improper feeding or misfires.

Inspect the magazine springs for signs of wear, and replace them if necessary.

9. Slide Won’t Go Back On

The main cause of the slide not going back on a Bersa Thunder 380 usually lies in the improperly positioned recoil spring assembly or the slide release lever.

There’s no need to worry; this is an easy fix with a few simple steps.

To resolve the issue, follow these steps carefully:

1. Remove the magazine and ensure the firearm is unloaded before proceeding. Remember always to practice safe firearm handling.

2. Inspect the recoil spring assembly. Ensure that it is correctly seated and aligned with the barrel. The thicker end of the spring should be resting on the front lip of the slide, while the thinner end should be around the barrel.

3. Once you have verified the proper placement of the recoil spring assembly, check the position of the slide release lever. This is a common issue when trying to reassemble the Bersa Thunder 380. The slide release lever must be positioned correctly for the slide to go back on smoothly.

4. To do this, align the slide release lever so that it is parallel to the ground with the firearm pointed upwards. The elbow-like curve at the end of the lever should be facing the rear of the gun.

5. After verifying the proper positioning of the slide release lever, you can begin reassembling. Hold the slide at a slight angle as you begin to slide it back onto the frame. This helps guide the slide onto the rails without any hang-ups.

6. When you are about halfway, tilt the firearm so the muzzle points downward. Gravity will cause the slide release lever to land in its desired notch, allowing you to smoothly slide back the rest of the way. Keep a firm grip on the slide, and do not force it.

7. After the slide is fully seated, lock it back using the slide release and carefully insert the takedown lever or pin back into its original position, completing the reassembly.
