The heart of this pistol is SIG’s serialized, stainless-steel fire control unit (FCU), which lets owners swap calibers and sizes as needed. Here, that FCU is paired with a Wilson Combat WCP320 grip module featuring Starburst texturing, an extended beavertail, and tungsten weight pockets for added stability.
A flat-faced X-Series trigger shortens reach and offers a consistent break, complementing the striker-fired action’s clean reset. Both forward and rear slide serrations provide positive traction for chamber checks and manipulations, while the matte black Nitron finish resists corrosion and glare.
Sight alignment is handled by TruGlo TG-H3 tritium 3-dot night sights, delivering quick target acquisition in daylight and low-light conditions alike. An integral five-slot MIL-STD-1913 rail accepts lights or lasers to further tailor the pistol to mission or range use.
The full-size 4.7-inch carbon-steel barrel maximizes velocity and offers a stable sight radius. With four 17-round magazines included, this P320 is ready for extended range sessions or duty use straight from the case.
