Common SIG P365 Problems, Fix & Reason

Failure to Extract

So, you’ve noticed your SIG P365 is acting a bit finicky and not ejecting spent casings like it should. It’s like it’s gotten too attached to them, right?

Well, don’t worry.It’s a typical issue known as a “failure to eject,” and it can really mess up your shooting groove.

Failure to Extract

The Solution

The key to solving the extraction issue is straightforward: maintain a clean chamber and ensure the extractor claw is functional. Regular cleaning of the chamber prevents buildup that can hinder casing ejection. 

Additionally, inspecting and maintaining the extractor claw for proper operation is crucial. This preventive maintenance ensures your P365 operates smoothly, enhancing your shooting experience without interruption.

The reason: Dirty chamber or broken extractor claw can hinder extraction process

Slide Lock Issues

Ever find yourself in a bit of a tussle with your firearm, where the slide seems to think it’s playing a game of hide and seek on that crucial last round? Or perhaps you’ve been in the ring, going toe-to-toe with an extended mag that seems to think it’s auditioning for the role of “World’s Heaviest Object”? 

Yeah, we’ve all been there. It’s like the gun decides to throw a mini-rebellion just when you need everything to run smoothly.

Slide Lock Issues


For the slide issue, it’s often about your grip. If you’re accidentally pressing on the slide lock, the slide won’t budge. Adjust your grip to keep clear of it.

As for the stubborn mags, it’s more about technique than muscle. A firm push and a bit of patience usually do the trick. 

No need for drama, just a small tweak in how you handle it, and you’re good to go.

The reason: Improper grip or worn magazine spring can prevent slide from locking back after last round

Night Sight Failures

Running into issues with your SIG’s first-gen night sights not lighting up your target as expected? 

It’s a common snag for early models, leaving shooters in the dark when accuracy matters most, especially in low-light conditions. Just when you need them, those sights seem to fade into the shadows. 

Night Sight Failures


SIG Sauer’s response? A serious upgrade to the X-Ray 3 Night Sights. Think of it as flipping on the high beams while cruising on a dark, winding road. 

These enhanced sights offer superior visibility and precision, ensuring your low-light aiming is spot-on. It’s SIG’s way of ensuring that when the lights go down, your confidence in hitting the mark goes up. Sometimes, Upgrading, warranty checking and alignment checking can solve the problem in this regard.

The reason: Early models had sights that could break or fail to illuminate.

Extended Magazine Loading

Ever felt like loading your SIG P365’s extended mag is a test of strength you didn’t sign up for? It’s like the magazine has its own stubborn personality, especially when it’s fresh out of the box.

Getting those last couple of rounds in can feel like you’re pushing against an immovable object. We’ve all been there, thinking, “Should it really be this tough, or is it just me?”

Extended Magazine Loading


First, consider using a mag loader. It’s not admitting defeat; it’s being smart. These handy gadgets take the grunt work out of loading, making it a breeze to get every round in place.

Plus, giving your mag a bit of a break-in period can work wonders. Load it up as much as you can, let it sit for a while, and you’ll find it becomes more cooperative over time. 

Remember, it’s not just you – those mags can be tough customers, but with the right approach, you’ll have them loaded up and ready to go without breaking a sweat.

The reason: Stiff magazine springs make loading challenging, especially when new.

Striker Drag

Noticed those odd marks on your spent shells and wondered, “What’s going on here?” That’s striker drag for you. It happens when the firing pin sticks around too long as the casing ejects, leaving a mark. 

Over time, this can wear out your striker. Not just annoying, but it could mess with your gun’s reliability too.

Light Primer Strikes


Seeing those marks and feeling worried? Keep an eye out for wear and tear. Something doesn’t look right? Time to get on the phone with SIG or swing by your local gunsmith. They might have the perfect fix or upgrade to get rid of those drag marks for good. 

Remember, staying on top of maintenance keeps your gun happy and reliable. So, why wait?

The reason: Excessive primer drag could indicate wear or need for adjustment.

The Battery Blues

Ever had one of those moments with your P365 where it just refuses to snuggle back into battery? Yeah, it’s a real vibe dampener. It’s like you’re all set for action, and your trusty sidekick decides to take a nap instead. What gives, right?

The Battery Blues


Hit with a P365 that’s playing hard to get into the battery? A gentle tap on the back of the slide might just coax it into place.

Regular, thorough cleaning and lubrication are your best bets for avoiding this snag. Dirt or grit in the slide rails or on the barrel can impede smooth movement. 

Using a high-quality lubricant in the right amounts on the slide rails, barrel lug, and other friction points helps ensure seamless operation. 

Plus, check the recoil spring; if it’s showing signs of wear or isn’t seated correctly, it could be time for a replacement.

Remember, a clean, well-lubricated P365 is a happy one that jumps into action when you need it.

The reason: Tight magazine fit or inadequate lubrication can prevent slide from fully returning to battery position
