Sig Sauer Custom Works P320 Fire Control Unit (FCU)
The Sig Sauer Custom Works P320 Fire Control Unit (FCU) program takes that idea and brings it to an unprecedented new level. From the beginning, the P320 was built to be a pistol that could adapt to meet the user’s specific needs. From grip modules and magazines to custom slides, barrels, and optics, the P320 can be configured in thousands of different ways to make your P320 unique and exactly the pistol you are looking for. The Sig Sauer P320 FCU features a titanium nitride frame as well as a titanium nitride skeletonized trigger that fits into all P320 frames.
