SIG P365 Problems With Their Practical Solutions

1. Bad (flawed) Striker Design:

First concern: the notorious firing pin breakage. This alarming problem occurred during dry-firing with an empty chamber. Users discovered their firing pin was prone to stress and damage.

The issue is largely attributed to intense pin drag against case primers. It results in unexpected and live discharges.

Such incidents raise significant safety concerns among firearm enthusiasts and demand swift attention to prevent further mishaps.

Through thorough testing conducted on post-2018 models, SIG confirmed the necessity of adjusting the striker’s strength and reconsidering its material and design.

This comprehensive approach aims to provide users with a viable solution to the notorious firing pin breakage problem.

Now, enthusiasts can take matters into their own hands by executing a simple swap from the old striker assembly to the new P365 striker assembly.

It ensures a smoother experience without burdening their wallets with additional expenses.

2. Gun Not Returning to The Battery:

Next, the gun is not returned to the battery as expected. This malfunction can be quite pesky and tends to occur frequently. This is particularly true for one particular magazine.

The problem often stems from a tight fit and inadequate lubrication. This exacerbates the issue and potentially compromises the firearm’s reliability and functionality.

Trust me, SIG P365 owners need to address this concern promptly to ensure a smooth operation.


Let’s seek a solution. A light tap on the magazine well or a firm rack of the slide can do the job in many cases.

For daily users, it’s essential to nip the issue in the bud by maintaining proper cleaning and greasing of the weapon.

This helps prevent excessive dirt and fouling from impeding the return-to-batteries process.

It ensures continuous use without the need for frequent maintenance.

With these practices, the possibility of the problem disappearing significantly increases.

3. Trigger Return Spring (TRS) Issues:

A concern that occasionally plagues the SIG P365 involves the trigger return spring (TRS).

Users may notice visible scuff marks and scratches on the surface of their pistol’s box magazines, an indicative sign of a potential problem with the TRS.

This ill-sized or long spring can lead to complications. This not only tarnishes the gun’s aesthetics but also leaves behind an unnecessary “rattle” movement that disrupts the smooth operation of the firearm.


To address the concern, the company has taken a proactive approach.

They’ve worked to ensure that the TRS is manufactured to the correct specification within the trigger group of newer models.

For older models experiencing issues, the remedy is to replace the existing spring with one that is correctly sized.

These replacement springs are sourced from reliable suppliers like Midwest.

While updating the TRS can reduce potential issues, it’s important to note that replacing parts in any firearm carries its own set of risks.

4. Slide Lock Function Issues:

Next, a problem emerged regarding its slide function. Users have observed instances where the slide fails to operate as intended.

This malfunction can lead to a failure to discharge a round. It is particularly true when the magazine is only partially inserted.

The slide may also fail to move forward after being pulled back, failing to return to its original position.

These issues often arise during the post-cleaning and reassembly process.

They leave the slide stuck or locked in place, which compromises the pistol’s functionality.


So, it was found that the issue could arise due to a tight slide release lever. To balance this, users should ensure that the takedown lever is properly engaged to allow for smooth rotation of the firearm’s components.

Keeping the firearm well-lubricated and clean can also help alleviate this issue.

During disassembly and reassembly, it’s important not to complicate matters by exerting excessive force.

Instead, gently squeeze the trigger to simplify the slide reassembly process.

5. Failure to Extract (FTE):

Ahh! Failure to extract! These failures occurred during the firing process, where the spent case failed to be properly extracted from the chamber.

The issue seemed to be particularly prevalent with certain types of ammunition. This is especially true with brass and silver-cased variants. It indicates a potential malfunction within the firearm itself.


One effective solution involves replacing the weak extractor spring.

By swapping out the existing spring with a new, more robust one, users can ensure the smooth functioning of their SIG P365 handguns.

Thereby reducing the risk of extraction failures.

6. Striker Drag:

One of the recurring issues faced by SIG P365 owners is striker drag. A phenomenon commonly observed in short-barreled, striker-fired handguns like the P365.

When the slide cycles, the cartridge may not be fully ejected. This results in the casing dragging along the primer end of the next round in the magazine.

This repetitive contact can cause wear and physical damage to the firearm. Result? It compromised its reliability and led to frustration among Sig owners.


Solution? Regularly inspecting spent casings becomes crucial to identifying any signs of the sig sauer romeo 5 problems problem’s severity.

Seeking assistance from a local gunsmith or contacting Sig Sauer directly is a practical approach to address the issue and prevent potential long-term damage to the firearm.

7. Trigger Reset Failure:

Experiencing trigger reset failure with the Sig P365 can disrupt the firearm’s normal operation. This leads to potential issues during the firing.

In normal operation, after a round is fired, the slide cycles back. reset the trigger to its forward position for the next shot.

However, users may encounter instances where the trigger fails to reset properly. This causes complications in subsequent firing sequences.


Here, a comprehensive solution involves several steps.

Firstly, thoroughly cleaning the firearm to remove any accumulated dirt or debris that may hinder the trigger’s motion is essential.

Ensuring that the trigger mechanism is free of obstructions can significantly mitigate the issue.

In addition to cleaning, replacing the trigger spring might be necessary. Especially if it has worn out over time or shows signs of fatigue.

Regular maintenance, including periodic inspections and dry-fire practice, can also help identify and address potential problems before they escalate.

8. Recoil Spring Assembly (RSA) Problem:

Do you know? The recoil spring assembly (RSA) within the Sig P365 is pivotal for its reliable operation.

Designed to absorb recoil after each shot, the RSA ensures the smooth return of the slide to the battery, a fundamental aspect of semi-automatic firearms.

However, reported issues with the RSA have raised concerns among users regarding the gun’s functionality and performance.

These issues can disrupt the overall shooting experience. They hinder the firearm’s effectiveness and reliability.

Here, a solution is right. Right?


A diligent approach to cleaning and inspecting the entire assembly is important. Any accumulation of dirt or debris within the RSA can compromise its functionality.

Replacing worn components is another crucial step in addressing the issue effectively.

If the problem persists despite these efforts, it is advisable to consult a local gunsmith for further diagnosis and resolution.

My Final Conclusion:

Don’t get me wrong: SIG Sauer P365 stands out as a compact gun.

But, it can have many problems, which I discussed in this article and gave you solutions.

For example, some issues stem from a flawed striker design and TRS intricacies. They led to slide complications and failure to extract (FTE) incidents.

These concerns don’t overshadow the firearm’s reliability and convenience.

The P365 offers a blend of virtues, including its compactness and robustness. This makes it an appealing choice for concealed carry and daily use.

It’s essential to understand that every firearm may encounter occasional setbacks.

However, with proper maintenance and adherence to recommended procedures, many of these challenges can be mitigated.

This allows users to enjoy the full potential of this compact firearm.
