The X01 in stock and shipping! The EXO ONE (X01) is a patent-pending multi-caliber exoskeleton for the Sig Sauer P320 Fire Control Unit (FCU).

In 20 seconds, you can change your 320 pistol into a legal, bigger, more capable pistol with no FFL and no tools. This is just the beginning.

I have had one of the prototypes for three months now and have fired thousands of rounds of 9mm and .40 through it with both mid-size and full size P320 slides. It runs great and everyone at the range wants to shoot it. My only complaint is that I had to buy more magazines because constant reloading was killing me.

The X01 body is injection-molded with glass filled nylon. It can accept SIG® MPX//MCX buttstocks and arm braces.  Read more at firecontrolunit.com
