Constructed from stainless steel and finished in Durable Nitron, the Sig Sauer 3.9" slide provides corrosion resistance and wear protection for long-term reliability. The built-in expansion chamber functions as an integral compensator, helping reduce felt recoil and muzzle rise without the need for threaded barrels or external devices.
The slide comes factory-equipped with a ROMEO-X Pro red dot sight, offering a crisp reticle and robust aluminum housing. Co-witness XRAY3 Day/Night suppressor-height sights provide backup aiming and are perfectly aligned with the optic window. Standard forward cocking serrations add enhanced grip for press checks and manipulations.
This slide is compatible with factory SIG 3.9" barrels and full-size recoil spring assemblies (sold separately), making it a drop-in upgrade for existing P320 setups.
Serrations: Standard Front and Rear Cocking Serrations
Application: Carry, Tactical, or Competition Slide Upgrade
