Sig Sauer BBLMODC9 P320 9mm Luger 3.9" Black Nitride Replacement Barrel

The Sig Sauer BBLMODC9 is a factory replacement P320 pistol barrel chambered in 9mm Luger. Measuring 3.90" long, it is engineered as a drop-in fit for the P320 Compact and P320 Carry modular pistols.

Machined from steel and finished in black nitride, this OEM barrel delivers the same factory dimensions and tolerances as the original, making it a reliable choice for pistol rebuilds, slide upgrades, or as a fresh spare. The black nitride surface treatment increases surface hardness and corrosion resistance for a long service life under range and carry use. No sights are installed, so the host slide's factory or aftermarket sight set controls the sight picture.

Designed specifically for the Sig Sauer P320 pistol family, the BBLMODC9 is the correct barrel for any compact or carry-length 9mm P320 slide configuration. Use this Sig Sauer factory replacement part to restore factory-spec performance or expand an existing build.
