Frequently Asked Questions

What are the essential tools needed to build a custom Sig Sauer P320 X Carry from an 80% FCU module?

You'll need a drill press (not a hand drill), a bench block, a hammer and punch set, specific drill bits, and cutting oil like Viper's Venom. A jig from suppliers like JSD Supply is also crucial for accurate drilling.

What is the recommended drill press speed for machining an 80% P320 FCU module?

For steel or aluminum FCU modules, a drill press speed of 1400-1600 RPM is recommended. This speed, combined with cutting oil, helps prevent drill bits from breaking during the process.

Are there any compatibility issues to be aware of when building a custom P320 X Carry?

Yes, standard P320 magazines may require filing of the baseplates to properly fit the wider X Carry grip module. Also, newer FCUs might need minor modifications for certain aftermarket triggers due to Sig's drop safety redesign.

Is building a Sig Sauer P320 from an 80% FCU module legal?

Yes, building a P320 from an 80% FCU module is federally legal in the United States. The components can be shipped directly to your home address, provided it complies with your local and state regulations.
