Sig Sauer P320 Custom Works FCU Titanium Frame Flat Trigger 9mm

The Sig Sauer P320 Custom Works Fire Control Unit transforms any P320 platform with premium titanium construction and precision trigger components. This serialized FCU serves as the foundation for building a completely customized P320 pistol tailored to specific shooting requirements.

What Makes This Different

The titanium frame construction reduces weight by approximately 30% compared to standard steel FCUs while maintaining structural integrity under heavy use. The flat-face skeletonized trigger provides consistent finger placement and reduces trigger pull weight to approximately 4.5-5 pounds. Black nitride coating on all steel components delivers superior corrosion resistance and reduces friction for smoother operation.

Key Features

• Titanium frame construction for reduced weight and enhanced durability
• Flat-face skeletonized trigger with improved geometry for consistent breaks
• Black nitride finish on steel components for corrosion resistance
• Compatible with 9mm Luger, .40 S&W, and .357 SIG calibers
• Accepts all standard P320 slides, barrels, and grip modules
• Drop-in installation with existing P320 components
• Serialized component requiring FFL transfer

This FCU maintains the P320's modular design philosophy while elevating performance characteristics. Competition shooters benefit from the consistent trigger break and reduced reciprocating mass. Law enforcement applications gain reliability advantages from the corrosion-resistant finish and lightweight construction. The universal caliber compatibility allows users to swap between different cartridges using appropriate slides and barrels.
