Sig Sauer P320 Custom Works FCU Gold Nitride Titanium Frame 9mm

The Sig Sauer P320 Custom Works Fire Control Unit transforms the modularity concept with precision-machined titanium construction and premium gold nitride coating. This serialized FCU serves as the foundation for building a custom P320 platform that exceeds factory specifications in both performance and aesthetics.

What Makes This Different

Unlike standard P320 fire control units, this Custom Works version features a lightweight titanium frame that reduces overall weight by approximately 30% while maintaining structural integrity. The gold nitride finish provides superior corrosion resistance and reduced friction compared to standard Nitron coatings. The flat-face skeletonized trigger delivers a crisp break with reduced pre-travel and over-travel for enhanced accuracy.

Key Features

• Precision-machined titanium frame construction for reduced weight and enhanced durability
• Gold nitride coating provides superior corrosion resistance and self-lubricating properties
• Flat-face skeletonized trigger with improved reset characteristics
• Multi-caliber compatibility: 9mm Luger, .40 S&W, and .357 SIG
• Compatible with all P320 grip modules, slides, and barrel assemblies

This FCU excels in competitive shooting environments where consistent trigger performance matters most. The titanium construction withstands high round counts while the gold nitride coating maintains smooth operation in adverse conditions. Law enforcement and military users benefit from the enhanced reliability and reduced maintenance requirements during extended training cycles.
