This is the genuine Sig Sauer factory replacement barrel for your full-size P320 in 9mm. At 5.5 inches, it matches the length of the standard full-size slide and comes threaded with 1/2-28 RH threads to accept most common muzzle devices and suppressors. The Nitron finish is tough and corrosion-resistant, holding up well to range use and the elements.
Sig Sauer heat-treats all their factory replacement barrels for exceptional toughness and longevity. This thermal processing makes the steel significantly harder and more resistant to wear compared to untreated barrels. If you're planning on running a suppressor or compensator regularly, or just want a barrel that will handle thousands of rounds without complaint, the heat treatment process really shows its value.
This barrel is designed specifically for full-size P320 pistols without a loaded chamber indicator (LCI). It's a straightforward drop-in replacement—no gunsmithing required. Simply unload your pistol, separate the slide from the grip module, and swap out the old barrel. The process takes just a few minutes. Note that this barrel is not compatible with P320 X-Five slides, so verify your specific model before ordering.
The 1/2-28 RH thread pitch is the industry standard for 9mm pistols, so you have plenty of options for suppressors, compensators, and muzzle brakes. A thread protector cap comes included to keep the threads clean when you're not running a muzzle device. The threaded design gives your full-size P320 real versatility without sacrificing the clean lines of your pistol.
This barrel works with full-size P320 pistols that do not have a loaded chamber indicator (LCI). It is not compatible with P320 X-Five slides. Check your specific model before purchasing to ensure compatibility.
