Why Choose This FCU

The P320 platform's genius lies in its modularity. By starting with a premium Fire Control Unit, you establish a reliable foundation for a truly custom pistol. Whether you're building a competition shooter, a duty weapon, or a personal defense firearm, this FCU delivers the precision and quality Sig Sauer is known for.

The titanium construction and gold nitride finish aren't just cosmetic—they represent a commitment to longevity and performance. The skeletonized trigger reduces unnecessary mass while maintaining the crisp, predictable break shooters demand.

Note: This is a Fire Control Unit only and requires compatible P320 grip modules, slides, and barrels to function as a complete pistol.
