The Faxon Duty Series Threaded Barrel For P320 Compact 9mm delivers a precise, drop-in upgrade for your SIG P320 Compact. Machined in-house from stress-relieved 4150 CMV steel and finished in a full salt bath nitride, this barrel is built for long service life, smooth operation, and consistent accuracy. Its 4.65" threaded muzzle with 1/2-28 threads is ready for suppressors, compensators, or a thread protector, while conventional button rifling and a 1:10 twist support a wide range of 9mm loads, including cast bullets.

This model is purpose-built for shooters who want dependable performance in a compact package, whether for range sessions, training, or defensive carry with a compatible slide. The tighter-than-factory tolerances promote improved lockup and repeatable point of impact, and the 11-degree target crown helps maintain precision shot after shot. Backed by Faxon’s reputation for careful machining and rigorous quality control, this barrel is a straightforward way to enhance your P320 Compact.
