The Sig Sauer P320 Compact 9mm Luger barrel is a direct replacement component engineered for shooters who want to upgrade, maintain, or customize their P320 or P250 Compact/Carry platform. At 4.6 inches, this threaded barrel opens the door to suppressor-ready shooting while maintaining the compact profile that makes these pistols so popular for carry and defensive use. Whether you're refreshing worn components or building a suppressed setup, this factory-quality barrel drops into your frame with straightforward field maintenance—no gunsmiths required.

The threaded 1/2"-28 muzzle is standard across modern 9mm suppressors and brake platforms, giving you real flexibility in how you configure your pistol. A thread protector cap is included to keep the threads clean and protected during storage or range sessions. Sig's Nitron finish delivers corrosion resistance and a professional look that matches the rest of your P320, and the steel construction ensures durability through thousands of rounds.

Barrel swaps on the P320 platform are refreshingly simple: unload, remove the slide from the receiver and grip module, and swap out the old barrel for this one. No special tools or guesswork—it's one of the reasons the P320 has become such a favorite for shooters who like to tinker and adapt their gear to their needs.
