The Zaffiri Precision P365 3" barrel is a match-grade drop-in replacement built for shooters who want precision and reliability from their compact 9mm. This non-threaded barrel ships with a flush crown and is engineered as a direct upgrade for your Sig Sauer P365, requiring no gunsmithing—just remove the factory barrel and install. Zaffiri manufactures these barrels in the USA using 416R stainless steel, heat-treated to exacting standards and stress-relieved for longevity. The black nitride finish offers corrosion resistance and a professional appearance that complements modern carry setups.

Built for accuracy from the ground up, this barrel features a fully supported chamber and improved feed ramp design that works reliably with lead, plated, and jacketed ammunition. The broach-cut rifling (1/10 left-hand twist, 6 groove) is paired with a polished bore and chamber to minimize fouling and maximize consistency shot to shot. The oversized lock-up area and target crown ensure tight tolerances and repeatable performance, whether you're running defensive loads or hitting the range.

The 3-inch length preserves the P365's compact profile while delivering the ballistic advantages of a proper match-grade barrel. The non-threaded design keeps things simple and streamlined—no suppressor ready configuration here, just a no-compromise barrel optimized for accuracy and reliability in a duty or carry pistol. The large "ZP" logo machined into the side is a subtle mark of quality and pride in craftsmanship.
