Sig P320 X-series 9mm 4.7" Or Sh Blk

The Sig P320 X-series 9mm 4.7" slide assembly in Sh Blk is a factory-engineered replacement component designed for law enforcement, military, and civilian shooters who demand modular performance and optic-ready capability. This slide assembly serves as the foundation for P320 X-COMPACT through X-FULL size pistols, enabling shooters to upgrade, repair, or reconfigure their platform without purchasing a complete new firearm. The modular P320 ecosystem has become the backbone of duty carry systems worldwide, and this slide represents SIG SAUER's commitment to weapon platform flexibility.

This slide assembly arrives pre-configured with optic-ready mounting that accommodates ROMEO1-PRO, ROMEO2, Delta Point Pro, and RMR (with sealing plate) footprints, giving operators multiple red-dot options for their specific mission profile. The integrated XRAY3 day/night suppressor-height sights provide absolute co-witness capability, ensuring point-of-aim accuracy with or without an installed optic—critical for defensive scenarios requiring rapid target transitions. The 4.7-inch barrel length and 9mm Luger chamber deliver the velocity and controllability expected from a duty-class platform, while the durable black nitride finish resists corrosion in harsh environments and provides a low-reflectivity sight picture. Engineered from precision-machined steel, this slide assembly maintains the tight tolerances required for reliability under sustained fire.

This replacement slide is ideal for officers upgrading existing P320 platforms, gunsmiths building custom configurations, or shooters transitioning between compact and full-size frames within the modular system. The compatibility with X-COMPACT through X-FULL lower receivers allows seamless integration into established duty or range setups. Installation requires basic takedown knowledge and proper reassembly technique; consult your P320 armorer's manual or SIG SAUER's official documentation to ensure correct function. Whether you're establishing a primary duty gun or building a backup platform, this factory-original slide assembly delivers the precision and reliability expected from America's most-adopted modern service pistol.
