The Faxon Sig P320 Fullsize 9mm Flame Flute Threaded Blk is a precision-engineered drop-in replacement barrel designed for law enforcement, military, and serious shooters who demand match-grade accuracy from their duty or defensive pistol. Built by Faxon Firearms—a manufacturer renowned for proprietary flame fluting technology—this barrel transforms the ergonomics and ballistic performance of the Sig Sauer P320 full-size platform. Whether you're upgrading for suppressor compatibility or seeking tighter shot groups at extended distances, this threaded barrel delivers the reliability and precision that professional operators expect.
Manufactured from 416R stainless steel billet stock and finished with salt bath nitride coating, this barrel offers superior corrosion resistance and durability in harsh field conditions. The flame fluted design reduces weight and heat signature while maintaining structural integrity—a refinement that matters during sustained fire or tactical operations. A 1:10" twist rate ensures optimal stabilization across the full spectrum of 9mm projectiles, from 115-grain target loads to 147-grain subsonic ammunition for suppressed fire. The 11-degree target crown and match-grade specifications guarantee reliable feeding and exceptional accuracy, while the threaded muzzle (1/2x28) accepts standard 9mm suppressors or muzzle devices without additional adapters.
Installation is straightforward—this is a true drop-in barrel requiring no gunsmithing or frame modifications for the Sig P320 full-size slide. Law enforcement agencies, competitive shooters, and civilian operators benefit from the immediate accuracy gains and suppressor readiness without altering the pistol's ergonomics or reliability. The 3.2-inch outer diameter and 7.85-inch length integrate seamlessly with standard P320 full-size components, making this an ideal upgrade for those seeking a combat-accurate, suppressor-ready platform without the expense or lead time of custom gunsmithing.
