This SIG Sauer factory threaded barrel (SIG part number 8900568) is built for the P320 X-Compact and Subcompact, chambered in 9mm with a 4.3-inch length. It is machined with a cut for the factory loaded chamber indicator, so it keeps that function working after installation, and it also fits any P320 variant designed around a 3.6-inch 9mm barrel. The 1/2-28 RH threading lets shooters mount a suppressor or other muzzle device, and a thread protector cap is included to cover the threads when nothing is attached.
