Factory- and 80%-compatible Sig Sauer P320 grip modules. 

The Sig P320 is one of the company's most unique and capable handgun platforms. That's thanks in large part to its high degree of modularity, which allows you, the shooter, to quickly and easily swap out one configuration for another. This includes the exterior frame of your P320 chassis, which is itself not considered a firearm under federal law. Instead called "grip modules", these high-quality polymer exoskeletons provide you with custom color options, Picatinny accessory rails, and an ergonomic, high-grip fit to make your P320 the perfect shooter.
