This SIG Sauer factory replacement barrel (SIG part number 8900790) is designed for the P320 Compact and Carry, chambered in 9mm and finished in Gold Titanium Nitride.

It is a non-threaded, standard-profile barrel meant as a direct factory replacement rather than a suppressor-ready upgrade, and its 3.9-inch length matches the factory-length P320 Compact and Carry slides.
