This video demonstrates the modularity of the Sig Sauer P320, showing how to convert a full-size model to compact or subcompact configurations. It details the disassembly process, focusing on the Fire Control Unit (FCU) as the serialized component. The tutorial covers reassembly with different grip modules and slides, highlighting the ease of customization and configuration changes.

Quick Summary

The Sig Sauer P320's modularity allows conversion between sizes by removing the Fire Control Unit (FCU), the serialized part. Disassembly involves rotating the takedown lever and pushing out the pin. The FCU can then be installed into different grip modules and paired with new slides.

Frequently Asked Questions

What makes the Sig Sauer P320 a modular pistol?

The Sig Sauer P320 is modular because its Fire Control Unit (FCU), which contains all the serialized components, can be easily removed and installed into different sized grip modules and paired with various slides, allowing for quick configuration changes.

How do you disassemble the Sig Sauer P320 for conversion?

To disassemble, first clear the firearm. Then, rotate the takedown lever 90 degrees and push the pin out from right to left to release the slide and internal components, allowing access to the Fire Control Unit (FCU).

What is the Fire Control Unit (FCU) in a P320?

The Fire Control Unit (FCU) is the core serialized part of the P320, containing the trigger mechanism and other essential components. It is legally considered the 'firearm' by the ATF and is what allows for the pistol's modularity.

Can you change the caliber of a Sig Sauer P320?

While this video focuses on frame and slide conversions, the P320 platform is known for its modularity, which can extend to caliber conversions by swapping the slide assembly and barrel, provided the FCU is compatible.
