The Zaffiri Precision P365XL 3.64" barrel is a match-grade upgrade for shooters who want to wring more accuracy out of their Sig Sauer P365XL. Unlike generic replacements, this non-threaded, stainless steel barrel is purpose-built for precision—stress relieved, heat treated, and finished to exacting standards that make a measurable difference on the range and in the field. It's the kind of drop-in upgrade that tells you the maker understands what separates a duty gun from a tack-driver.
Built from 416R stainless steel and manufactured in the USA, this barrel features a fully supported chamber and improved feed ramp design that work reliably with all bullet types—lead, plated, and jacketed. The precision-machined target crown and oversized lockup area minimize runout and maximize consistency. Six-groove broach-cut rifling with a 1-in-10 left-hand twist and a polished bore give you the accuracy gains you're after without any breaks-in nonsense.
The non-threaded flush crown design means this barrel integrates cleanly into your P365XL's profile while delivering the performance you need. It's SAAMI spec chambered and ready to install—just drop it in and shoot. A distinctive large "ZP" logo is machined into the lockup area, a subtle mark of quality that shows Zaffiri stands behind their work.
