SIG P320 FCU DISASSEMBLY AND REASSEMBLY: Learn how to maintain your Sig P320 FCU

Our P320 FCU Disassembly and Reassembly Video will walk you through disassembling the Fire Control Unit down to its individual components. From there we walk you through the P320 FCU reassembly.

Normally you do not need to disassemble the P320 FCU however, there are times that you need to maintain the pistol when parts break or wear out. Also, if your Sig P320 was in a flood or submerged in water from a natural disaster, a P320 FCU Disassembly and inspection is critical to make sure that there was no damage.
