SIG Sauer P320 Full 9mm 18-Round Pistol

The SIG Sauer P320 Full 9mm is the modular duty-grade platform trusted by federal, state, and local law enforcement agencies nationwide. This full-size striker-fired pistol delivers the reliability and ergonomics that armed professionals demand in high-stress scenarios. With an 18-round magazine capacity and refined ergonomic design, the P320 Full combines tactical capability with shootable accuracy for defensive and service applications.

Built on SIG's battle-proven modular platform, the P320 Full features a steel slide and polymer fire-control unit that separates from the grip module for simplified maintenance and customization. The 4.7-inch barrel delivers superior velocity and sight radius compared to compact variants, enhancing accuracy at defensive distances. A consistent, manageable trigger break and superior ergonomic controls—including ambidextrous slide catch and magazine release—ensure fast, reliable operation under pressure. The full-size frame and extended sight radius make follow-up shots faster and more precise than compact platforms.

This configuration appeals to duty officers, security professionals, and serious civilian shooters who prioritize capacity and shootability. The P320 Full accepts standard P320 holsters, magazine carriers, and aftermarket components, making integration into existing tactical systems straightforward. Its modular architecture allows grip-module swaps for size customization, while the rails support tactical lights and laser systems. Whether configured for duty carry or home defense, the P320 Full provides the capacity, control, and reliability that defensive shooters expect from a modern service pistol.
