The modular, serialized fire-control unit is the heart of the P320 system, allowing easy caliber and grip-size changes without additional FFL transfers.
Factory SIGLITE tritium 3-dot night sights provide a clear, non-electric sight picture day or night, and the slide’s front and rear cocking serrations offer positive grip for press checks and manipulations.
An ambidextrous manual thumb safety complements the striker, disconnect, and trigger-tab safeties, meeting Massachusetts compliance while adding layered mechanical protection.
The compact Nitron-finished stainless slide houses a 3.9-inch stainless steel barrel and mirrors the dimensions of the U.S. military’s M18, giving a balance of shootability and concealability.
Three steel Mec-Gar magazines (one 15-round, two 10-round) come standard, providing reliable feeding and compatibility with the pistol’s textured polymer grip module and integral accessory rail.
