Sig Sauer P320 Conversion (How To)

Published on March 30, 2018
Duration: 2:06

This guide details the process of converting a Sig Sauer P320 pistol, specifically demonstrating how a P320 X5 can be modified using its modular components. The video, presented by Rich Morovits, a Sig Sauer Corporate Trainer, emphasizes the importance of the Fire Control Unit (FCU) as the serialized part and shows how it can be transferred between different grip modules and slide configurations. Proper safety procedures for clearing the firearm are demonstrated before disassembly and reassembly.

Quick Summary

The Sig Sauer P320's modularity allows for easy conversion by transferring the serialized Fire Control Unit (FCU) to different grip modules and slides. This process involves safe disassembly, removing the FCU, installing it into a new grip module, and reassembling with a desired slide, enabling configuration changes from full-size to compact or carry models.

Frequently Asked Questions

What is the serialized part of a Sig Sauer P320?

The serialized part of the Sig Sauer P320, considered the 'firearm' by the ATF, is the Fire Control Unit (FCU). This component houses the trigger mechanism and must be transferred legally during sales.

How do you disassemble a Sig Sauer P320 for conversion?

To disassemble, first ensure the pistol is unloaded. Lock the slide, remove the magazine, and clear the chamber. Rotate the takedown lever 90 degrees, push out the takedown pin, and lift out the FCU.

Can a Sig Sauer P320 X5 be converted to a smaller size?

Yes, the P320's modular design allows for conversion. The Fire Control Unit (FCU) from a P320 X5 can be transferred to different grip modules (compact, carry, subcompact) and paired with various slides.

What is the role of the Fire Control Unit (FCU) in P320 conversions?

The FCU is the legally defined 'firearm' for the P320. It contains all the critical components for firing and is the only part that needs to be serialized and transferred. It's moved between different grip modules and slides for configuration changes.
