Common SIG P365 SAS Problems and How To Fix

Check out some of the most common Sig P365 SAS problems and their solutions.

1. Failure To Feed

Have you ever encountered a failure-to-feed issue with your SIG P365 SAS handgun? If so, you’re certainly not alone. This problem is one of the most common issues encountered with the SIG P365 SAS and can cause many frustration for owners.

But what exactly causes this failure to feed issue, and how can it be addressed? Let’s look at the main causes of this problem and how to correct it. An inadequate magazine usually causes the failure to feed issue with the SIG P365 SAS.

The magazine may be old, damaged, or incompatible with the gun. If the magazine is not functioning correctly, the gun may not be able to feed the rounds properly, failing to feed. The wrong type of ammunition or improper loading may also contribute to this issue.

To address the failure to feed issue, begin by inspecting the magazine. Check for signs of wear and tear and any damage, such as bent or missing feed lips.

If the magazine appears in good condition, try a different type of ammunition or ensure it is loaded properly. If the magazine is damaged or old, it may need to be replaced. Cleanliness is also key in addressing the failure to feed issue.

The gun should be thoroughly cleaned and inspected for debris preventing rounds from feeding properly. A good cleaning and lube job can go a long way towards restoring the gun’s reliability.

Finally, it’s important to ensure that the magazine is firmly seated in the gun and that the release is not stuck. If the magazine is not being seated properly, the gun may not be able to feed the rounds reliably.

2. RTB (Return to Battery) Problem

Are you having trouble with RTB issues in the SIG P365 SAS Gun? If so, you’re not alone. Many people have experienced this issue, and finding a solution can be frustrating. Luckily, you can do a few things to help alleviate the issue.

The first cause of RTB issues in the SIG P365 SAS Gun is when the gas system has not been properly tuned. This means the gas pressure is too high or too low for the particular load you’re shooting.

If the gas pressure is too high, it can cause the gun to cycle too quickly and cause the bolt to ride back for a long period. If the gas pressure is too low, it can cause the gun not to cycle at all.

To fix this issue, you’ll need to adjust the gas system of your gun until it is properly tuned for the particular load you’re shooting. Another common cause of RTB issues in the SIG P365 SAS Gun is when the recoil spring is too weak. If the recoil spring is too weak, it can cause the gun not to cycle properly and result in the bolt riding back for a long period.

You’ll need to replace the recoil spring with a stronger one to fix this issue. Finally, another cause of RTB issues is if there is a malfunction in the trigger assembly.

If the trigger assembly is not functioning properly, it can cause the gun not to cycle properly and result in the bolt riding back for a long period. You’ll need to take apart the gun and inspect the trigger assembly for any issues to fix this issue. You’ll need to replace the trigger assembly if there are any issues.

3. Jamming Issues

One of the most common causes of jamming in SIG P365 SAS guns is inadequate lubrication. When a gun isn’t properly lubricated, friction increases as the slide moves back and forth, leading to buildup of dirt, dust and debris that can create blockages in the firing chamber.

Regularly cleaning your gun and applying a quality lubricant can help prevent jams from occurring due to lack of lubrication.

Another cause of jamming is incorrect ammunition being used in the gun. Using reloaded or substandard ammunition can cause problems such as misfires or jams due to improper fit between the bullet and chamber walls.

Always use quality new ammunition for your SIG P365 SAS to reduce chances of jamming issues.

Improper magazine insertion can also lead to SIG P365 SAS gun jams. Make sure that you fully insert your magazine into the magwell before engaging the slide stop lever so that it sits securely against the frame—this will ensure any cartridges inside are correctly aligned with the barrel’s breech face when they are chambered.

If you experience a jam while shooting your SIG P365 SAS, stay calm and use safe handling practices while clearing it.

Lock back the slide to ensure there is no live round in the chamber, then use an appropriate tool (such as an unloading tool) to clear out any obstruction preventing the slide from cycling smoothly.

4. Magazine Release Button Problem

This is a common issue that many people face with their SIG guns and can be easily resolved. The magazine release button may become stuck due to the accumulation of dirt or other debris, which prevents it from being activated. The dirt or debris can also cause problems when inserting the magazine into the gun’s chamber.

The problem with the magazine release button on the SIG P365 SAS gun can be traced back to two main issues. First, the button is made out of a lightweight plastic material.

This material is not strong enough to withstand the pressure to release the magazine. Secondly, the button is too small and difficult to press, making it difficult to use.

Fortunately, there are some solutions available to address this problem.

First, you can replace the plastic magazine release button with a metal one. Metal buttons are much stronger and more durable than plastic ones and can withstand the force of being pressed. Additionally, you can purchase a larger button, which is easier to press and more comfortable to use. You can also adjust the tension on the magazine release button.

This can be done by using a flathead screwdriver to loosen the tension on the button. This will make the button easier to press and will also reduce wear and tear on the button over time. Finally, you can lubricate the button. This will help to reduce friction and make it easier to press.

Use a lubricant specifically designed for firearms, as other lubricants may damage the gun.

5. Failing to Lock Open After the Last Round: 

Many SIG owners have experienced this issue, which can be incredibly frustrating. Several factors, including a worn-out recoil spring, a dirty or damaged magazine, or an overly-tightened extractor, can cause this.

The most common cause of this issue is a worn-out recoil spring. Over time, the spring can become weak and unable to cycle the slide properly. If this is the issue, the solution is simple: replace the recoil spring.

To ensure optimal performance, SIG recommends replacing the recoil spring every 3,000-4,000 rounds. Another possible cause is a dirty or damaged magazine. Residue from ammunition can build up inside the magazine and cause the rounds not to feed properly.

This can also be caused by a damaged magazine, such as one that has been dropped or has sustained damage from extensive use.

If so, you should thoroughly clean and inspect the magazine for damage. If the magazine is damaged, it should be replaced. Finally, an overly-tightened extractor can also cause this issue.

The extractor is the gun part that pulls the rounds from the magazine and chambers them. If the extractor is too tight, it can cause the rounds not to feed properly, and, as a result, the gun won’t lock open after the last round. If this is the issue, the solution is to adjust the extractor tension.

6. Reassenmbly Problems

Reassembly problems with the P365 SAS often arise due to the gun’s unique design.

The gun slide is designed to be incredibly tight, which helps reduce recoil and improve accuracy. However, taking the gun apart and reassembling it properly isn’t easy.

The main cause of reassembly issues is that the slide is too tight, which makes it difficult to get everything back in place. To solve this problem, lubricate the gun before reassembling it.

This will help to reduce friction and make it easier to reassemble the gun. Additionally, you may need to use a punch or screwdriver to help push the slide into place.

You can also gently tap the slide into position with a plastic mallet. Use light taps and gentle movements, as too much force can damage the gun.

It’s also important to ensure all the components are in the correct position before you try to reassemble the gun. Otherwise, the slide may not fit properly, and the gun may jam. Finally, if you’re having trouble getting the slide back on, you can use an allen key to loosen the slide lock. This should make it easier to reassemble the gun.

6. Recoil Spring Rod Problems    

The recoil spring rod of a SIG P365 SAS Gun is a vital part of the firearm, as it helps to absorb the recoil force created when a round is fired. It also helps to return the slide to its original position, ready to fire another round.

Over time, however, the recoil spring rod can become worn down, resulting in inadequate force being applied to the slide. This can lead to difficulties such as slide jams, misfires, and even the firearm failing to fire. There are a few different ways to address this problem.

The first is to replace the recoil spring rod with a new one. This will give the firearm a new lease of life, as it can apply the correct amount of force to the slide and ensure reliable operation. However, this can be a costly exercise, as the recoil spring rod is not a cheap part to replace.

The second option is to thoroughly clean and lubricate the recoil spring rod. This can help reduce friction and wear, extending the part’s life and improving the firearm’s overall performance.

It’s important to ensure the part is properly lubricated and not over-lubricated, as this can lead to problems such as slide jams and misfires. Finally, if you’re having problems with the SIG P365 SAS Gun’s recoil spring rod, it’s worth considering servicing it professionally.

7. Accuracy issues

The SIG P365 SAS is a semi-automatic pistol that shoots one bullet at a time. This type of firearm has some inherent accuracy issues compared to other types, such as revolvers, bolt action rifles and single-shot shotguns.

This is because semi-automatic pistols tend to produce more movement during the firing cycle due to their rapid rate of fire. This movement causes a decrease in accuracy, which often results in inaccuracy when shooting targets at distances over 25 yards.

Fortunately, there are several things you can do to improve the accuracy of your SIG P365 SAS gun. One such solution is improving your shooting stance by ensuring you have a solid foundation from which to shoot. Also, proper grip technique is essential for consistent accuracy; ensure your grip is firm but not too tight.

Furthermore, practice dry firing your gun regularly to become familiar with the trigger pull and increase your familiarity with the firearm.

Finally, ensure that any ammunition you use is reliable and accurate; always test out different brands or weights before settling on one specific load for target practice or competition shooting.

8. Poor Sight Alignment

Have you ever noticed that your SIG P365 SAS gun may not always have perfect sight alignment? Various factors, such as incorrect holster positioning, improper grip, and recoil, can cause poor sight alignment. Additionally, the gun’s trigger pull can also cause poor sight alignment.

To ensure proper sight alignment, the shooter should practice proper grip technique and hold the gun firmly in the same position while shooting.

Additionally, using quality holsters designed specifically for the SIG P365 SAS gun can help to reduce improper holster positioning.

Finally, shooters must practice proper trigger control to not jerk or pull the trigger, which could lead to improper sight alignment.

9. Slide Problems

The main reason for slide problems is excessive wear of the parts that make up the slide assembly. This includes recoil springs, recoil buffer assemblies, slide stops, and frame rails.

Over time these parts may become worn or weakened from constant use, and they must be replaced to ensure that your gun operates properly.

In addition to wear-and-tear on the parts, improper maintenance can contribute to slide problems. Dirt and debris can build up inside the pistol over time and interfere with the function of the slide assembly components.

Additionally, not cleaning or lubricating your gun regularly will lead to increased friction between moving parts which may affect the movement of the slide or cause other issues such as jamming or misfiring.

Fortunately, there are a few easy steps you can take to help keep it functioning properly:

Firstly, regularly inspect all of its components for signs of wear and tear; secondly, ensure it is kept clean and well lubricated; finally, replace any worn or damaged components as soon as possible to maintain optimal performance.
