This SIG Sauer factory replacement barrel (SIG part number 8900791) is designed for the P320 Full-Size, chambered in 9mm and finished in Gold Titanium Nitride for added lubricity over a standard finish. At 4.7 inches, it is a non-threaded, standard-profile barrel built as a direct factory replacement rather than a suppressor-ready upgrade. It is only compatible with slides and pistols that do not use the loaded chamber indicator, and it is not compatible with X-Five-length pistols, so confirm your slide and frame configuration before ordering.
