Sig Sauer P365 Custom Works FCU Gold Nitride Titanium Frame 9mm/380

The Sig Sauer P365 Custom Works Fire Control Unit transforms any P365 build with premium materials and enhanced trigger performance. This serialized FCU serves as the foundation for custom P365 configurations while delivering the precision expected from Sig's Custom Works division.

What Makes This Different

The gold nitride finish provides superior corrosion resistance compared to standard phosphate coatings, extending service life in harsh environments. The titanium frame construction reduces weight by approximately 15% while maintaining structural integrity under high round counts. The flat-face trigger design delivers a consistent 90-degree break angle, improving trigger control and reducing pull weight variability.

Key Features

• Gold nitride finish for enhanced corrosion resistance and lubricity
• Titanium frame construction reduces overall weight while maintaining strength
• Flat-face trigger provides consistent finger placement and improved break
• Compatible with both 9mm Luger and 380 ACP P365 configurations
• Accepts all standard P365 grip modules, slides, and barrels
• Custom Works quality control with tighter tolerances than production models
• Serialized component requiring FFL transfer

This FCU maintains the P365's reputation for reliability while adding premium materials typically found in competition firearms. The gold nitride treatment reduces friction between moving parts, contributing to smoother cycling and extended maintenance intervals. Law enforcement agencies and competitive shooters appreciate the consistent trigger reset and reduced pre-travel that comes standard with this unit.
