P320 Fire Control Unit

SIG SAUER P320 Custom Works Fire Control Unit (FCU)

From the very beginning, the P320 was designed to be a pistol that can be customized 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’re looking for.

The P320 CustomWorks Studio FCU program takes this concept to a whole new level. Watch the video to get a closer look at what this program has to offer. You can also click one of the buttons above to either start building your custom P320 or purchase your CustomWorks P320 Fire Control Unit.
