Sig Sauer Custom Works P320 Fire Control Unit (FCU)
The Sig Sauer Custom Works P320 Fire Control Unit (FCU), is a serialized firearm and is required to ship to an FFL dealer.

Starting with the FCU you can add P320 grip modules, barrels, and slides to make a customized P320 pistol. Want multiple custom P320 pistols? Just take the FCU out of one setup and place it in another.

Everything from a sub compact concealed carry pistol to a competition X-5 is possible with FCU.

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.
