The SIG P320 is a semi-automatic pistol. SIG Sauer has manufactured this gun with a modular design which you can configure with your choice of calibers and other options.<\/p>\n\n\n\n

But, you may face some issues with the SIG P320. The most common SIG P320 problems are firing pin problem, ejector bending, trigger not resetting, takedown lever issue, and magazine movement.<\/strong><\/p>\n\n\n\n

1. Firing Pin Problem:<\/h3>\n\n\n\n

Numerous instances of firing pin problems resulted in injuries to people. Their SIG P320 pistols started firing without them pushing the trigger.<\/p>\n\n\n\n

In rare instances, dropping the gun might trigger it. Additionally, there have been instances of this issue when the user attempted to holster it.<\/p>\n\n\n\n

The Fix:<\/h4>\n\n\n\n

SIG Sauer released an optional upgrade for their P320 handgun in April 2023 to address safety concerns. The upgrade features a redesigned sear and a new firing pin safety system.<\/p>\n\n\n\n

So, if you have bought the gun before the upgrade, you should install a new firing pin. If you send the gun back to SIG, they can fix it for you.<\/p>\n\n\n\n

According to the manufacturer, the modification will stop the rifle from shooting when the trigger is not pushed.<\/p>\n\n\n\n

2. Ejector Bending:<\/h3>\n\n\n\n

The ejector bending is one of the most common SIG P320 problems. It typically occurs when a 21-round full-size magazine is inserted firmly enough.<\/p>\n\n\n\n

This might occur if the user tries to close the slide before the magazine is properly inserted in the slot. The ejector may drag on the slide if it is deformed. Your gun will lock up as a result of this.<\/p>\n\n\n\n

The Fix:<\/h4>\n\n\n\n

You might try to bend the ejector back into place to solve the issue. You need to use needle nose pliers to accomplish this.<\/p>\n\n\n\n

You should take care not to over-bend the ejector, though. This might make things even worse. Take the rifle to a gunsmith if you are uncomfortable bending the ejector back into place.<\/p>\n\n\n\n

Another choice is to just swap out the ejector. For the P320, SIG Sauer supplies new ejectors.<\/p>\n\n\n\n

3. Trigger Not Resetting:<\/h3>\n\n\n\n

A common problem with the SIG P320 gun is that the trigger does not want to reset sometimes. You can also notice the inconsistency with the split times.<\/p>\n\n\n\n

When disassembling and reassembling the gun, you will notice that the trigger will not want to reset.<\/p>\n\n\n\n

This problem might be brought on by a trigger bar spring that was distorted. The fire control system itself can also be flawed.<\/p>\n\n\n\n

The Fix:<\/h4>\n\n\n\n

Make sure the trigger bar spring is not deformed or damaged by carefully inspecting it. If so, it might need to be changed.<\/p>\n\n\n\n

To check for any obvious damage that might be preventing the trigger from resetting, remove the FCU from the frame. Make sure nothing is damaged and that everything is seated correctly.<\/p>\n\n\n\n

Disconnect the takedown safety and take out the FCU. Now, you should manually operate the trigger to determine if it resets correctly when separated from the slide assembly.<\/p>\n\n\n\n

4.  Takedown Lever Issue:<\/h3>\n\n\n\n

During field stripping, the takedown lever is in charge of disengaging the takedown safety. Trigger pull difficulties may arise if the takedown safety is not seated correctly in the slide lock hole during reassembly.<\/p>\n\n\n

It is possible for the SIG P320’s takedown safety to not seat properly due to tolerance variances. During reassembly, the factory lubrication may have an impact on how components move.<\/p>\n\n\n\n

The Fix:<\/h4>\n\n\n\n

Follow these steps to fix the issue:<\/p>\n\n\n\n
