SIG P365 Problems

Last Update:

Hey Gunners, Welcome to my SIG P365 Problems Blog In 2023.

As an avid shooter, I tested the SIG P365, and let me tell you, it was an eye-opener. 

As many of you know, this compact pistol has been making waves for its size-to-capacity ratio and general usability. 

But during my hands-on time, a few problems reared their heads. I encountered issues with extraction failure, slide problems, a less-than-ideal striker design, trigger issues, and jamming. 

I will break down these issues one by one and then offer you solutions to tackle them head-on. We’ll ensure your SIG P365 is running as smoothly as possible, enhancing your safety and shooting experience.

QuicK Sig p365 Issues & Solutions

Extraction FailureUpgrade to a new, robust extractor spring to ensure proper ejection of spent cases.
Slide ProblemsEnsure the takedown lever is fully rotated, keep the firearm well-lubricated, and avoid squeezing the trigger during disassembly.
Problem with StrikerReplace the old striker assembly with a new P365 striker assembly to improve reliability.
Trigger IssueReplace the Trigger Return Spring (TRS) with a correctly sized one for older models or consider upgrading to a newer model.
Jamming IssueUse high-quality, factory-made ammunition, maintain and lubricate the firearm, and consider swapping older magazines for new ones.

Top 5 SIG P365 Problems & Solutions

1. Extraction Failure

Ah, yes, the dreaded Failure To Extract issue. This snag happened to me when I was putting the SIG P365 through its paces at the range. 

Specifically, I was firing rounds with brass and silver-cased ammo. Right when I thought I had everything down, boom; an issue. 

The spent case would just stick around in the chamber like an unwanted guest. Clearly, it’s a big no-no, especially if you’re in a situation where you can’t afford a malfunction. 

So, what’s causing this mess? Upon closer examination, the extractor spring seemed like the weak link in the chain.


Let’s get down to business. The issue primarily came from a weak extractor spring, so it was time for an upgrade. I got myself a new, robust extractor spring and popped it in. Just like that, the problem was as good as gone. 

No more stubborn cases hanging around in the chamber. The new spring ensured that each spent case was ejected properly, making the shooting experience a lot smoother.

So, if you’re running into extraction issues with your SIG P365, a new extractor spring could be your ticket to a more reliable shooting experience. Trust me, it worked wonders for me.

2. Slide Problems

Let’s talk about another issue that gave me a bit of trouble: complications with the slide function. 

During my rigorous field testing of the SIG P365, I noticed the slide wasn’t always playing nice. After emptying a magazine, the slide would just partially inch forward instead of fully retracting. 

Oh, and get this: the slide even got stuck a few times, particularly after cleaning and during reassembly. A slide that doesn’t behave is more than a small issue; it’s a reliability concern, especially when you need the firearm to function correctly.


So what did I do? After a bit of tinkering and analysis, I pinpointed the issue to a tight slide release lever. 

The fix? Make sure the takedown lever is fully rotated when you’re dealing with this problem. Sounds simple, but it makes a world of difference. I also found that keeping the gun well-lubricated helps in this case. 

And here’s a pro tip: don’t squeeze that trigger during disassembly; it only makes slide reassembly trickier. Follow these steps, and your slide should operate smoothly. Take it from me: it worked like a charm.

3. Problem with the Striker Design

Now we get to the elephant in the room: the flawed striker design. During my time with the SIG P365, I noticed something that had already made the rounds in firearm circles: the issue with the firing pin breaking. 

No kidding, my first run-in with this happened while I was dry-firing into an empty chamber, something lots of us do. What’s the catch? The firing pin tends to suffer stress and damage, mainly because of significant pin drag on the case primers during live firing. 

It’s a significant concern, given that a malfunctioning firing pin could compromise your safety.


Now, for the good news. SIG apparently caught wind of this flaw and made adjustments to the striker design.

I can attest to this improvement, having tried out models manufactured after 2018. If you’re grappling with this issue, here’s the remedy: switch out the old striker assembly with a new P365 striker assembly. Seriously, it’s that straightforward. 

The cost is manageable, and the result? A significantly more reliable firing pin leads to a better, safer shooting experience. It worked for me, and I bet it’ll work for you too.

4. Trigger Issue

Alright, let’s dive into another problem: issues with the Trigger Return Spring, or TRS for short. 

How did I figure this out? Well, the signs were there: visible scuffs and scratches on my pistol’s box magazines. Trust me, no one likes an unsightly magazine. 

Digging deeper, it was apparent that an ill-sized TRS was the culprit. Not only did this long TRS mess up the look of my magazines, but it also introduced an annoying “rattle,” throwing a wrench into the smooth operation of my SIG P365.


On to the solutions. SIG Sauer stepped up by fixing the TRS in newer models, making sure it’s 

up to spec. 

If you’re stuck with an older model, you could replace the existing TRS with a correctly sized one from a reliable source like Midwest. But if you ask me, updating to a newer model might be your best bet. 

Why? Swapping parts can sometimes invite new problems, and going for a newer model just sidesteps this issue altogether. 

5. Jamming Issue

Let’s get into one of the more nerve-wracking problems: jamming. While putting the SIG P365 through its paces, I had a few instances where the firearm jammed on me. 

And let’s be real; a jammed weapon is not just an annoyance; it’s a safety hazard. The issue seemed to occur more frequently with older magazines and certain types of ammunition, which is still no excuse for a firearm that’s supposed to be top-tier. 

A jam at the wrong time can spell disaster, making this issue far from trivial.


Okay, so how did I resolve this? First things first, make sure you’re using high-quality, factory-made ammunition; it does make a difference.

Second, be diligent about cleaning and lubricating your firearm; a clean gun is generally a reliable one. I also went ahead and swapped out my older magazines for new ones. 

The result was a noticeable improvement in performance and fewer jams. But remember, firearms are complex machines and can still face wear and tear over time. 

So, regular maintenance checks are a must. I found these steps immensely helpful, and they might just do the trick for you, too.

Final Thoughts

After spending ample time with the SIG P365, my conclusion is this: Yes, the firearm has its fair share of problems, but hey, show me a machine that doesn’t!

The good news is that most of these issues are fixable. The company itself has made improvements in newer models, especially addressing some significant concerns like the striker design. 

From my hands-on experience, a bit of attention to maintenance, using quality parts, and following the solutions outlined can transform this gun into a reliable tool.

The SIG P365 offers better capacity than the Glock 43, making it the winner if ammunition capacity is a priority for you.

Which is better P365 or P365XL?

The P365 is shorter in grip length and therefore easier to conceal, but the P365XL has advantages like better recoil mitigation due to its longer grip.

Is the Sig P365 snappy?

Yes, the SIG P365 has a snappy recoil, although the P365XL offers slightly better recoil management due to its longer grip.
