SIG Sauer P365 Custom Works Black Fire Control Unit

The SIG Sauer P365 Custom Works Fire Control Unit is the serialized core of a modular P365 build. Manufacturer part number 8900165 is identified by its black nitride finish and flat trigger and is intended for compatible 9mm and 380 Auto P365 configurations. Because the FCU is the serialized firearm component, it must transfer through a Federal Firearms License holder and is not a complete pistol.

A factory foundation for a custom P365

The FCU allows the owner to select a compatible grip module, slide, barrel, magazine, sights and optic around the serialized operating unit. SIG describes the P365 FCU platform as compatible with its 9mm and 380 Auto P365 accessories, but individual components still must match the intended caliber and final configuration.
