SIG P320 Problems

Last Update:

Welcome to my SIG P320 Problems Blog.

I’ve had the chance to take the SIG P320 out for quite a few runs. While using it, I’ve encountered a handful of SIG P320 Problems that seemed to pop up more often than I’d like. 

I’ve grappled with extraction failure, problems with the lever, feeding issues, failure to fire, and even some trigger complications. 

The good news? I’ve also found solutions for these issues. My goal here is to share them with you. That way, you can enjoy your SIG P320 without any headaches.

Quick SIG P320 issues & Solutions

Top 5 SIG P320 Problems & Solutions

1. Extraction Failure

Ah, the dreaded extraction failure. In my time using the Sig P320, this has been one of the more pesky issues I’ve run into, especially when using TulAmmo. 

Picture this: You’ve just fired a shot, and you’re ready to fire again, but bam! An empty shell decides it wants to hang out in the barrel a little longer. It’s frustrating, to say the least. 

I found myself unable to manually rack the slide to remove the spent shell. I tried, folks, but that shell was acting like it paid rent to stay there.


After a lot of tinkering, I figured out a way to tackle this. I took apart the gun and made sure the spring was properly placed. Then, reassembled it and tried firing it again. 

Most of the time, this did the trick. But if this sounds like too much hassle, or if the issue just won’t quit, it might be time to reach out to Sig Sauer customer service. They could potentially replace the extractor for you. 

And trust me, sometimes it’s better to let the experts handle it.

2. Problem with the Lever

Now, let’s dive into the lever problem I stumbled upon. The takedown lever on the Sig P320 just wasn’t cooperating. And let’s be honest, the last thing you need is a takedown lever throwing a tantrum when you’re out in the field. 

I wasn’t in the mood for games. After some close inspection, I realized the issue was an interfering guide rod. Yup, the guide rod was out of line, and it made the whole operation of disassembling the gun a hassle.


Here comes the easy part. My solution was pretty straightforward. I locked the slide back and checked to see if the guide rod was tilted or misaligned. 

Then, I nudged it gently until it was parallel to the slide. It was like magic—everything clicked into place! After that, the takedown lever was back to being my friend. No more stubbornness, just smooth operation.

So there you have it. If you find yourself wrestling with the takedown lever, give that guide rod a little nudge. It could save you a whole lot of stress and get you back to enjoying your Sig P320 the way you should.

3. Feeding Issue

Alright, let’s talk about another issue that can be a real pain: feeding problems. While using the Sig P320, I’ve had times where the ammunition just wouldn’t load into the chamber as it should. 

This is not something you want to deal with, especially when timing is crucial. Whether you’re at the range or in a situation where you need your firearm to perform, a feeding issue can throw a wrench into your plans. 

I examined the magazine, the chamber, and even the ammo itself, looking for the culprit.


So, what did I do to get past this? I started by cleaning the magazine. Dirt and debris can accumulate and mess with the smooth operation of the ammo feed. 

Then I inspected the feed ramp; this often-overlooked part plays a crucial role in how ammo gets from the magazine to the chamber. A quick cleaning and polishing of the ramp worked wonders. Finally, I examined the type of ammunition I was using. 

Certain brands may not feed as smoothly, so consider switching if you encounter consistent issues.

Remember, the key here is a well-maintained weapon. Regular cleaning and choosing the right ammo can go a long way in preventing feeding issues.

4. Failure To Fire

Next on my troubleshooting list is Failure to Fire, commonly known as FTF. It’s incredibly irritating when you pull the trigger, and all you get is a disappointing click instead of a bang. 

In my experience, this often occurred after reassembling the Sig P320. I tried to use the same tricks I’ve used on other Sig P-series pistols, like nudging the slide back into place and flipping the takedown lever. 

But guess what? Doing that caused misalignment issues in the P320, leading to the dreaded FTF.


Now, for the fix. I went back to basics. The instruction manual is there for a reason, right? Instead of trying to find a shortcut, I used the slide lock to ensure proper internal clearance during reassembly. 

Sure, it might take an extra second or two, but guess what? No more FTF issues. The slide and internal components aligned perfectly, allowing the gun to fire as expected.

So, if you find yourself with an FTF after reassembling your Sig P320, stick to the book and use that slide lock. It’s a small step that can save you from a big headache later on.

5. Trigger Problem

Last but definitely not least is the trigger issue, and trust me, it’s one that’ll make you scratch your head. 

While using the Sig P320, I noticed the trigger wasn’t as responsive as it should be. I’d pull it, and it would either stick or feel gritty, making for a less than ideal shooting experience. In the heat of the moment, that kind of inconsistency can really throw you off. 

I mean, when you’re out there, you need your trigger to be as reliable as the sunrise. This problem needed a fix, pronto.


So what’s the remedy for this trigger trouble? I started by disassembling the trigger assembly for a good, thorough cleaning. 

Sometimes, grit or small debris can get lodged in the works, causing that sticky feeling. Once it was clean, I applied a light coating of gun-specific lubricant to the moving parts, taking care to avoid over-lubing, which can attract more dirt. And lo and behold, the trigger was back to its smooth self.

Bottom line? A clean trigger assembly and a dash of the right lubricant can go a long way in solving trigger issues. So don’t overlook the small stuff; it really makes a difference.
