SIG Sauer P320 Full 9mm 18-Round Pistol

The SIG SAUER P320 Full 9mm Nitron with Romeo-X is a professional-grade striker-fired pistol engineered for law enforcement, military, and serious civilian operators who demand reliability under pressure. This full-size variant delivers the capacity and control needed for duty carry, training, and defensive applications where performance cannot be compromised. The integrated Romeo-X red dot sight system elevates target acquisition speed and accuracy, making this platform ideal for officers transitioning to modern optic-ready duty weapons.

Built on SIG's proven modular P320 platform, this full-size configuration features a 4.7-inch barrel optimized for velocity and sight radius, while the Nitron finish provides superior corrosion resistance in harsh environments—critical for long-term reliability in field conditions. The 17+1 capacity offers tactical flexibility between engagements, and the X-Ray 3 night sights ensure target visibility in low-light scenarios where most defensive encounters occur. The polymer frame delivers a durable, lightweight platform that reduces fatigue during extended wear, while maintaining the ergonomic grip geometry proven across thousands of duty weapons worldwide.

Law enforcement agencies, military units, and armed professionals benefit most from this configuration's combination of mechanical precision and optical modernization. The P320 platform's modular design accommodates future grip module changes and accessory integration, ensuring long-term investment value. Magazine compatibility with standard P320 full-size platforms and widespread parts availability make this an operationally sound choice for departments standardizing on the P320 system. Weighing one pound unloaded, it maintains the balance and maneuverability expected in professional duty use.
