Rival Arms will offer standard and threaded barrels for the Sig Sauer P365, P365 XL, P320 Carry, P320 Full Size, and P320 X5 pistols. All Rival Arms barrels start with a stainless-steel billet to deliver maximum durability and are then precision CNC-machined to exacting tolerances to ensure the greatest possible accuracy before being treated with a PVD coating. This coating provides exceptional wear and corrosion resistance and is available in black or gold colors. Threaded barrels come with 1/2-28 threads for use with popular aftermarket suppressors and compensators. A color-matching thread protector is included for use without muzzle devices.
