Sig P320 X-series 9mm 3.6" Or Sh Blk

The Sig P320 X-series 9mm 3.6" slide assembly is a factory-engineered replacement component designed for serious shooters who demand modularity and optic-ready capability from their compact duty or defensive platform. This slide assembly allows you to upgrade your P320 X-Series frame without needing to purchase a complete firearm.

Built with SIG SAUER's commitment to precision manufacturing, this slide features an integrated optic mounting system that accepts industry-standard footprints—ROMEO1-PRO, ROMEO2, Delta Point Pro, and RMR (with sealing plate)—providing flexibility to run the red dot solution that matches your operational requirements. The slide ships with XRAY3 day/night suppressor-height sights, allowing co-witnessed aiming when your optic is mounted.

This slide assembly is purpose-built for P320 X-Series shooters seeking upgrade paths without purchasing a complete new pistol. The durable, hardened steel construction ensures consistent accuracy and longevity even under demanding training cycles or defensive use, while the 3.6" barrel length maintains the X-Compact's ergonomic footprint ideal for appendix or strongside carry.
