Zaffiri Precision BA-P365-TH-BN 9mm Luger 3.75" Threaded Barrel - Fits Sig Sauer P365 - Black Nitride

The Zaffiri Precision BA-P365-TH-BN is an aftermarket threaded pistol barrel built for the Sig Sauer P365. Machined from 416R stainless steel and finished in a low-reflective black nitride coating, this drop-in barrel is chambered in 9mm Luger and is broached and honed to a SAAMI-spec chamber for reliable feeding and consistent accuracy.

The barrel measures 3.75 inches and is cut with 1/2x28 muzzle threads, giving P365 shooters the option to mount a compensator or suppressor while keeping a clean, factory-look setup. A thread protector is included to keep the threads clean and protected when no device is installed.

Whether you are building a suppressed carry pistol, dialing in a compensated range gun, or simply want a more durable replacement for the factory barrel, the Zaffiri Precision threaded P365 barrel offers the precision, fit, and finish that have made the brand a favorite among pistol builders.
