If you're running a Sig Sauer P365XL and want to dial in accuracy without replacing the whole gun, a match-grade barrel upgrade is one of the smartest moves you can make. The Zaffiri Precision ZP.365XLBTBN is a threaded 9mm barrel built to tighter tolerances than factory, giving you the kind of precision you'd expect from a purpose-built competition or duty pistol. Drop it in, and you've got a USA-made upgrade that transforms how your compact carries and shoots.
This is a threaded barrel—1/2 x 28 at the muzzle, with a thread protector included—so it'll work with suppressors, flash hiders, or any compatible muzzle device. The 4.30-inch length keeps you in compact-carry territory while the 416R stainless steel construction means it'll stand up to years of shooting and cleaning. Zaffiri stress-relieved and heat-treated the steel to RC 40–42 hardness, so you're not getting a soft or brittle tube; you're getting something built to last. The bore and chamber are polished and shaped to feed and fire everything from plinking ammo to quality defensive loads—no finickiness about bullet type.
The engineering details matter here: a fully supported chamber, improved feed ramp design, target crown, and an oversized lock-up area all work together to reduce wear, improve reliability, and keep your groups tight. Conventional broach-cut rifling with a 1-in-10 left-hand twist completes the spec sheet. Important note: Threaded barrels aren't legal everywhere. Before ordering, verify your local and state laws—you're responsible for compliance.
