The SilencerCo 9mm Threaded Barrel for the Sig P320 Compact (SilencerCo part no. AC2486) turns the pistol into a suppressor-ready host. It is a 4.5-inch barrel in 416R stainless steel with a black nitride finish. It arrives threaded 1/2×28 straight from SilencerCo, so no gunsmithing is required. A thread protector ships with it. It is the P320 Compact version, so it is the one to choose over the full-size barrel.
