The Backup Tactical Threaded Barrel for the SIG P320 Compact in black (Backup Tactical part no. S320TB-BLK) is machined specifically for the standard P320 Compact with the 3.9 inch SIG factory barrel, not the P320 X-Series Compact with its 3.6 inch factory barrel, which SIG has since discontinued. That distinction matters for fit, so shooters should confirm their factory barrel length before ordering. Once installed, the threaded muzzle accepts a compensator or suppressor without further gunsmithing.
