Sig Sauer P320 9mm Luger 4.60" Threaded Replacement Barrel - Black Nitron

The Sig Sauer P320 9mm Luger 4.6" Threaded Barrel is a factory replacement barrel built specifically for the modular Sig Sauer P320 platform. Designed to fit the P320 Compact, P320 Carry, and P320 XCARRY variants, this barrel lets you swap configurations or add a muzzle-ready option to your existing pistol. Chambered in 9mm Luger and machined to CIP specification for reliable feeding and accuracy, it is a direct drop-in upgrade for the popular P320 family.

At 4.60" long, this barrel is sized for the compact and carry-length P320 slides. It is finished in Black Nitron, the same durable coating used on Sig Sauer's factory slides, giving it a clean factory look and excellent corrosion resistance. The barrel incorporates a Loaded Chamber Indicator (LCI) for a visible and tactile indication of chambered status. There are no integrated iron sights on this barrel, allowing end users to install their preferred sights or run the factory slide-mounted sights as intended.

The barrel features 1/2x28 RH threads at the muzzle, so you can mount standard 9mm pistol muzzle devices, compensators, or thread-on suppressors. This makes it an ideal choice for owners who want to add a suppressor or comp to their P320 Compact, Carry, or XCARRY without sending the pistol in for custom work. Like all Sig Sauer factory parts, it is engineered to factory tolerances for drop-in fit and reliable function with quality 9mm Luger ammunition.
