SIG Sauer P320 Full 9mm 18-Round Pistol

The SIG Sauer P320 Full 9mm is the modular duty-standard semi-automatic pistol trusted by law enforcement, military units, and professional shooters worldwide. This full-size variant delivers the proven reliability and accuracy that have made the P320 platform the sidearm of choice for federal, state, and local agencies. Whether for duty carry, training, or sport shooting, the P320 Full offers the ergonomics and performance required in high-stress environments where dependability is non-negotiable.

Built on SIG's legendary short-recoil operating system, the P320 Full 9mm features a 4.7-inch barrel and ships with an 18-round magazine, providing substantial capacity for extended engagements or tactical operations. The striker-fired action delivers a consistent trigger pull geometry essential for precision under pressure, while the full-size frame accommodates a standard grip module for maximum control and recoil management. The modular serialized chassis design allows users to customize grip sizes, trigger groups, and fire control assemblies—a critical advantage for shooters seeking a platform that adapts to individual hands and mission requirements rather than forcing the shooter to adapt.

Law enforcement officers, military personnel, and civilian professionals benefit from the P320 Full's proven track record and extensive aftermarket ecosystem. The 9mm chambering offers cost-effective training and reduced recoil impulse compared to larger calibers while maintaining sufficient stopping potential for duty and defensive applications. The 18-round capacity exceeds most service pistol competitors, and the P320's modular architecture ensures long-term relevance—components remain compatible across generations, supporting platform investment and serviceability for years to come.
