Sig Sauer P320 9mm Luger 4.30" Threaded Barrel - Nitron - Fits X-Compact/Subcompact

The Sig Sauer P320 9mm Luger 4.30" Threaded Barrel (part 8900568) is a factory OEM replacement barrel engineered for the P320 X-Compact and P320 Subcompact pistols. Chambered in 9mm Luger, this barrel allows the host slide to be configured for use with a suppressor, compensator, or other 1/2x28 muzzle device.

The barrel carries the factory Black Nitron finish for corrosion resistance and a low-friction surface, and is machined with 1/2x28 RH threads to industry-standard spec. An integrated Loaded Chamber Indicator (LCI) matches the original feature set of the X-Compact and Subcompact pistols. A thread protector cap is included to keep the threads clean and protected when no device is mounted.

Cut to factory tolerances for a drop-in fit, this Sig Sauer barrel installs directly into the X-Compact or Subcompact slide without additional fitting. The barrel ships with no sights installed, allowing the host pistol's existing iron sights or red-dot setup to be retained. Built to original Sig Sauer specifications, the 8900568 threaded barrel is a reliable solution for shooters configuring a threaded P320 slide or replacing a worn original.
