SIG Sauer P320 Compact 9mm 3.9" Optics Ready 10rd - Black

The SIG Sauer P320 Compact delivers modular versatility and striker-fired reliability in a mid-size platform optimized for concealed carry and duty use. This optics-ready variant features a 3.9-inch barrel and 10-round capacity, making it compliant with restricted states while maintaining the P320's renowned accuracy and modularity.

What Makes This Different

The P320's modular fire control unit allows complete customization of grip size, barrel length, and caliber without requiring additional background checks or transfers. The optics-ready slide comes factory-milled to accept popular red dot sights including Romeo1Pro, DeltaPoint Pro, and RMR footprints. Unlike traditional striker-fired pistols, the P320 features a completely removable trigger group that enables quick configuration changes in minutes.
