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 engineered for serious shooters who demand modularity and optic-ready capability from their compact duty or defensive platform. This slide assembly transforms your P320 Sub-Compact or X-Compact frame into a modern, precision-capable system without requiring complete firearm replacement. Law enforcement and tactical professionals rely on the P320 X-series platform for its unmatched customization depth and proven reliability in the field.

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)—giving you flexibility to run the red dot solution that matches your operational requirements. The slide ships with XRAY3 day/night suppressor-height sights, a critical feature for shooters pairing optics with sound suppressors; suppressor-height sights allow co-witnessed aiming when your optic is mounted. The durable, hardened steel construction ensures consistent accuracy and longevity even under demanding training cycles or defensive use, while the 3.6" barrel length preserves the X-Compact's ergonomic footprint ideal for appendix or strongside carry.

This slide assembly is purpose-built for P320 Sub-Compact and X-Compact shooters seeking upgrade paths without purchasing a complete new pistol. Installation requires basic takedown knowledge; the modular P320 platform makes slide swap straightforward for end-users. Ideal for competition shooters, armed professionals, and self-defense-minded civilians who want one platform capable of supporting multiple optic options and suppressor-ready sighting. Compatibility with both factory and aftermarket barrels in the X-series ecosystem makes this a smart foundation for building your ideal compact 9mm platform for sale or personal use.
