Zaffiri Precision P365XL Ported Barrel

The factory P365XL barrel is a non-ported, standard-profile part with no gas venting. This match-grade ported barrel redirects propellant gas upward through precision-cut ports, counteracting muzzle rise for faster follow-up shots — but it requires a Zaffiri Precision ported slide to function, making it part of a dedicated upper build rather than a standalone barrel swap.

Fitment notes: Drop-in fit for Sig P365XL. PORTED barrel — compatible ONLY with Zaffiri Precision ZPS.4 and ZPS.P slides. Will NOT work with OEM or other aftermarket slides. Flush & crown (non-threaded). 416R stainless, broach-cut 6-groove rifling, 1:10 LH twist. SAAMI spec chamber. 3.64" length. Made in USA.
