Troubleshooting Common Issues When Removing the FCU on Your SIG P320
The first step is to ensure that the firearm is not loaded and the magazine is removed. After that, the slide should be locked back to the rear. To do this, press the slide lock lever upwards and hold it in place. Once the slide is in the locked open position, you will need to depress the takedown lever. This is a small lever located on the left side of the pistol. Depressing the takedown lever will allow you to separate the slide from the frame.
If the slide still does not separate, you may need to take a look at the slide lock lever. Ensure that the slide lock lever is not in the down position. If so, it should be moved to the upward position. Additionally, you may need to check the lugs on the slide lock lever. These are small protrusions located on the lever that need to be aligned properly with the slide. If they are not aligned correctly, the slide will not separate from the frame.
Once the slide is separated, you should be able to remove the FCU. Make sure that the takedown lever is in the up position and the slide lock is in the down position. Then, depress the trigger and push the FCU out of the frame.
