New Hampshire-based Sig Sauer is putting its money where its mouth is when it comes to the inherent modularity of its popular P320 series pistols by shipping standalone Fire Control Units as a base for custom work.

Teased earlier this year and now a reality, the P320 Custom Works Fire Control Unit consists of the serialized portion of the system, with no barrel, grip module, slide, or magazine. Available through licensed firearms dealers, individuals can pick up the ATF-controlled FCU, then elect to finish out any way they want. The units are complete with a gold titanium nitride finish and the company’s Legion series trigger. The units will have a dedicated FCU Serial Number (FCU ###), and be compatible with 9mm, 357 SIG, and 40 S&W calibers.

"The P320 pistol is renowned for both its unprecedented modularity and unmatched capability to become the pistol of choice amongst firearms enthusiasts and all branches of the U.S. Military,” said Tom Taylor, Sig's CMO and EVP.  "The soul of the P320, and the driving force behind its modularity, is the patented, serialized fire control unit that gives the consumer the ability to build their dream pistol from the ground up."

Buyers will be able to register their product on Sig’s Custom Works P320 Studio which will allow them to “test drive” builds much in the same way that car makers have long allowed visitors to explore different models. 

The P320 Studio gives the consumer an online experience to build a P320 pistol from the ground, trying various grip modules, slides, barrels, guides and springs, optics, or complete CAL-X Kits with the virtual P320 configurator.
