SIG Sauer P320 Compact 9mm 3.9" Optic Ready 15rd Black

The SIG Sauer P320 Compact delivers striker-fired reliability in a versatile platform that adapts to multiple roles. This optic-ready variant features a 3.9-inch barrel and ships with a 15-round magazine, offering substantial firepower in a compact frame. The modular FCU design allows users to reconfigure the pistol across different grip sizes and barrel lengths without additional background checks.

What Makes This Different

The P320's serialized Fire Control Unit represents a fundamental shift in pistol design philosophy. Unlike traditional firearms where the frame holds the serial number, the FCU contains all regulated components in a removable chassis. This innovation enables users to swap between compact, carry, and full-size configurations instantly. The optic-ready slide eliminates machining costs while maintaining zero integrity across multiple sight systems.

Key Features

• Modular Fire Control Unit transfers between grip modules without FFL transfer
• Optic-ready slide accepts RMR, DeltaPoint Pro, and Romeo1 Pro footprints
• 3.9-inch stainless steel barrel with 1:10 twist rate
• 15-round flush-fit magazine with witness holes
• SIGLITE night sights with tritium inserts
• Reversible magazine release accommodates left-handed shooters
• Nitron-finished slide resists corrosion and wear

Range testing consistently produces 2.5-inch groups at 25 yards with quality ammunition. The 90-degree break angle and 5.5-pound trigger pull weight provide predictable shot placement for both precision shooting and rapid engagement sequences. Law enforcement agencies report function rates exceeding 99.8% through 10,000-round service intervals. The compact grip length conceals effectively while maintaining full firing grip for all hand sizes.
