SIG Sauer P320 FCU with Skeletonized trigger, Factory NEW. *THIS IS A FIREARM AND REQUIRES AN FFL TRANSFER*

A little late to the party, but here is SIG's OEM Standalone P320 complete FCU with all Factory SIG FCU parts and the Legion trigger.  Details are not finalized, but it appears to include the flat, skeletonized trigger from the X5 Legion model and a TiN Gold coating. The FCU will work with most P320 9mm, 40SW or 357SIG (not 45ACP or manual safety versions). ALL FCU PARTS are post-upgrade with the new drop parts. Will not work with pre-upgrade slide. Note: this product is yet to be released by SIG so there may be changes to the production version.

Includes: Factory SIG Sauer serialized FCU, all SIG FCU parts assembled in frame with skeletonized, flat trigger, extended X-Series slide catch and takedown lever. SIG has stopped including the safety lever spring in the FCU. No Slide, optic, grip, etc. included. Pistol shown for reference only. (SIG Part #130XXXX).


Prices include shipping to your FFL.

Barrel, Slide, Grip, Magazines, Chamber flag, etc. are NOT INCLUDED.

FFL is REQUIRED for transfer of frame. Serialized frame not available in CA unless Law Enforcement. Federal law requires that the purchaser must be 21 years of age or older to transfer a serialized frame.

For quickest shipping please have your FFL send their license to our email: We will only ship to the FFL address.
