### Detailed Features

The Gold Nitride finish is a hard surface treatment that improves wear and corrosion resistance while giving the unit a distinctive gold appearance. The flat face trigger geometry changes where the finger contacts the trigger face, which some shooters find improves consistency and the perceived pull weight. At 1 lb and 6 inches, this is the FCU alone. The complete pistol requires a grip module and slide assembly.

The P320's modularity means this FCU can be moved between different grip modules and slide configurations as needs or laws change.
