Common Problems and Solutions

Recoil Spring Issues

The recoil spring in the SIG P320 X5 Legion can sometimes cause performance hiccups. If the spring is too stiff or too weak, it can lead to issues like the slide not returning to battery properly, or it might affect the ejection and feeding of rounds. Essentially, it messes with the smooth cycling of your pistol.

Recoil Spring Issues


If you’re feeling adventurous, swapping out the standard recoil spring for a 1911 guide rod paired with a lighter spring might just do the trick. This can help smooth out the action and improve reliability.

Don’t feel like tinkering? No worries. Reaching out to SIG for guidance or assistance is always a smart move.

Trigger Pull Problems

Some shooters find the trigger pull on their P320 X5 Legion a bit off – either too heavy, too light, or just inconsistent. This can really throw off your shooting rhythm and accuracy.

Trigger Pull Problems


There are a few roads you can take here. A professional trigger job can make a world of difference, offering a smoother, more consistent pull.

Alternatively, exploring aftermarket triggers that suit your preference can also be a game-changer. Sometimes, just replacing the firing pin block can improve the trigger feel significantly.

Battery Blowout Issues

‘Battery blowout’ sounds dramatic, and it can be concerning. It refers to issues with the optic’s battery failing, which can leave you literally in the dark if you’re relying on it for accuracy.

Battery Blowout Issues


First step, check in with SIG Sauer. Their customer service can offer guidance, and there might be warranty or repair options available. Also, regular checks and maintenance of your optic can prevent surprises.

Sight Issues

Aligning sights and maintaining accuracy can be challenging, especially if the sights become loose or if they’re not calibrated correctly.

Sight Issues


Regular maintenance is key. Tighten and check the alignment of your sights frequently. If you’re still having trouble, consider a professional sight adjustment or even upgrading to a higher-quality sight that holds its zero better.

Slide Locking and Failure to Eject (FTE)

Slide locking or FTE issues can be frustrating, often stemming from improper lubrication or the use of incorrect ammunition.

Slide Locking and Failure to Eject (FTE)


Keep your SIG P320 X5 Legion clean and well-lubricated. Also, experiment with different ammunition brands or types. Sometimes, the gun can be picky about what it likes to eat.

Magazine and Feeding Problems

Magazines can sometimes be the culprit behind feeding issues, whether it’s due to wear and tear, dirt, or a weak spring.

Magazine and Feeding Problems


Regularly clean your magazines inside out and inspect the springs and followers for any signs of wear. Replacing magazine springs or even the entire magazine can resolve many feeding issues.

Ergonomic Concerns

The grip might not feel right for every shooter, leading to discomfort or a lack of control during firing.

Ergonomic Concerns


Customization is your friend here. Adjusting grip size and placement, applying grip tape, or experimenting with different backstraps can significantly improve the ergonomics. Making the pistol feel like an extension of your hand is the goal.
