JK Armament JKBBLS320C 9mm Luger 3.90" Black 416 Stainless Steel Sig P320 Compact Threaded Barrel

The JK Armament JKBBLS320C is a drop-in 9mm Luger replacement barrel engineered specifically for the Sig P320 Compact pistol. Machined from 416 stainless steel with a Black finish, this 3.90" threaded barrel serves as a direct-fit replacement for the factory P320 Compact unit.

Built as a direct-fit replacement for the factory P320 Compact slide, the JKBBLS320C is profiled for the Compact-length 9mm P320 platform. The 416 stainless steel construction offers excellent corrosion resistance and dimensional stability, while the precision-cut bore and rifling support consistent performance. A thread protector is included to shield the muzzle threads when the barrel is run without a compensator or suppressor attached.

Whether you are upgrading a factory slide, replacing a worn barrel, or building a dedicated P320 Compact pistol, the JK Armament JKBBLS320C provides a quality drop-in option. Installation is straightforward: field-strip your P320 Compact, drop the JK Armament barrel in place of the factory unit, and reassemble.
