Sig Sauer P320 9mm Luger 3.9" Gold Titanium Nitride Replacement Barrel - Compact/Carry

The Sig Sauer P320 3.90" Gold Titanium Nitride Replacement Barrel is a factory-direct 9mm Luger barrel engineered to drop into the P320 Compact and P320 Carry pistol slides. Machined from steel and treated with a durable Gold Titanium Nitride (TiN) coating, this barrel gives P320 owners a straightforward way to refresh a worn factory tube, swap a configuration, or add a striking gold accent to a carry pistol without sending the slide to a gunsmith.

The P320 platform is built around a serialized Fire Control Unit (FCU) that accepts a wide variety of grip modules, slides, and barrels, which is what makes a factory replacement barrel the simplest path to reconfigure the pistol. This 3.90" barrel is chambered in 9mm Luger and is built specifically for the Compact/Carry length slide, delivering the original-spec fit, feed, and accuracy that Sig Sauer's modular system was designed around. The Gold Titanium Nitride finish lays down a hard, low-friction surface that resists corrosion, makes cleaning easier, and stands up to the heat and pressure of repeated cycling.

This is the NO LCI version of the 3.9" P320 Compact/Carry barrel, meaning the chamber end is not cut for a Loaded Chamber Indicator so it properly matches Carry slides that omit that feature. No sights are mounted on the barrel itself - Sig Sauer's slide-mounted sights stay in place during a barrel swap. With basic field-stripping and standard armorer procedures, the barrel drops into the locking block and locks up exactly the same as the factory original, keeping factory headspacing and reliability intact.

Condition on this new Sig Sauer barrel is unused factory stock, ready to install in any compatible P320 Compact or P320 Carry slide.
