Faxon Firearms Match Series 365B910Nfsoqt P365 Strght Fluted
A Faxon Firearms Match Series P365 barrel built to tighter specs than your pistol came with. If you shoot a SIG P365 and want to upgrade to a precision drop-in barrel that improves lockup, reliability, and longevity without guesswork or gunsmithing, this straight-fluted 9mm from Faxon's Match line is engineered to do exactly that. It's machined in-house from stress-relieved 416-R stainless steel, finished with black Nitride coating, and ready to seat into your factory slide the moment it arrives.
The upgrade path here is straightforward: Faxon's better-than-OEM tolerances translate to a tighter barrel-to-slide fit that improves shot-to-shot consistency and reduces play at lockup. The conventional rifling profile accepts a broader range of ammunition, including cast lead rounds, so you're not locked into premium factory ammo to get reliable function. The 11-degree target crown and 1:10 twist are optimized for 9mm precision, and the Nitride coating boosts lubricity and wear resistance—your barrel will shoot cleaner and last longer than a softer, uncoated alternative.
This is a working upgrade for shooters who demand reliability and better fit without the downtime or cost of a gunsmith visit. Drop it in, and you've got a precision component that respects your P365's potential.
