Sig Sauer P320 9mm Luger 4.30" Threaded Black Nitron Barrel

The Sig Sauer P320 9mm Luger 4.30" Threaded Barrel is a factory replacement and upgrade barrel built specifically for the P320 X-Compact and P320 Subcompact modular handgun platforms. Chambered in 9mm Luger and measuring 4.30" long, this barrel gives compact and subcompact P320 owners a longer, threaded option for suppressor or compensator use while keeping the factory slide footprint.

The barrel features a 1/2x28 RH thread pitch - the standard pattern for 9mm muzzle devices - and ships with a thread protector cap to keep the threads clean and protected when no device is installed. Sig Sauer's signature Black Nitron finish is applied for corrosion resistance and a low-glare surface, matching the look and durability of the factory pistol slide.

Designed as a drop-in barrel for the P320 X-Compact and P320 Subcompact slides, this unit carries no sights and is intended to use the host pistol's existing sight system. It is an ideal solution for shooters looking to add a suppressor or muzzle device to their compact P320 without permanently modifying the factory barrel, or simply to replace a worn original.
