The heart of this pistol is SIG’s serialized, removable fire-control unit (FCU), allowing the user to swap grip modules, slides, and calibers while keeping the same firearm on paper. This modularity means the buyer can tailor the P320 to multiple roles without additional paperwork.
The compact Nitron-finished slide features front cosmetic cuts and rear cocking serrations for solid purchase during manipulations. Fixed 3-dot sights provide a clear, traditional sight picture, and the slide is cut for the factory optics plate (not included).
A 3.9-inch carbon-steel barrel with nitride treatment resists corrosion and wear, while the striker-fired action and crisp trigger break enhance consistency shot to shot. Internal striker and disconnect safeties add mechanical security without external levers.
The polymer grip frame houses a full 5-slot Picatinny rail for lights or lasers, extending the pistol’s versatility for defensive or duty use. At 15+1 rounds of 9mm Luger, the P320 Compact balances capacity and concealability in a platform that remains in active production and support.
