The P320 Compact format delivers a 3.9 inch barrel and a 13+1 capacity in .40 S&W, with a striker-fired action and a textured polymer grip module for secure handling. This variant is the non-manual-safety configuration and is designated by mfg part number 320C-40-BSS.
Sight picture is handled by dovetailed tritium 3-dot night sights, with the rear unit marked "MH3 AO." The slide features front and rear serrations and a matte black finish. The slide has no optics cut.
The modular design centers on SIG's removable, serialized fire-control unit (FCU), allowing the core of the pistol to be moved between compatible P320 grip modules and calibers. The FCU serial matches the label on the included factory case. Manufacturer markings note SIG Sauer, Newington, NH, and the pistol is made in the USA.
On the frame, a 4-slot accessory rail on the dustcover supports common weapon lights or accessories. Three steel magazines are included; each is stamped "MADE IN ITALY" and features 13-round witness holes.
