The Faxon Match Series Barrel for Sig Sauer P365 XL is a threaded 9mm drop-in barrel built for shooters who demand accuracy and durability without paying match-grade prices. Faxon manufactures these barrels in-house from 416-R stainless steel, starting with stress-relieved bar-stock and finishing with Nitride treatment inside and out. The result is a barrel that stands up to hard use, cleans easily, and resists corrosion—whether you're running duty rounds through a duty gun or chasing tight groups at the range.

What sets the Match Series apart is attention to the details that actually improve performance. The 5R hybrid rifling design—lands positioned opposite grooves with reduced sharp angles—minimizes jacket deformation, which means higher velocity and easier cleaning between strings. The 11-degree target crown promotes consistency shot to shot. The extension wears a Nickel Teflon coating that delivers dry lubricity and corrosion resistance while tightening the fit between extension and receiver for better accuracy.

This is a threaded barrel, so you've got the option to run a suppressor or muzzle device if your setup calls for it. The 1/2x28 TPI threading is standard for 9mm. Drop-in design means no gunsmithing—install and run. If you're looking to upgrade your P365 XL with a precision barrel that won't nickel-and-dime you, the Faxon Match Series delivers the performance and value that's made Faxon a go-to name in the precision barrel space.

Frequently Asked Questions

Will this threaded barrel fit my P365 XL without modifications?

Yes. This is a drop-in barrel designed specifically for the Sig Sauer P365 XL. No gunsmithing or fitting is required—install and run.

Can I use a suppressor with this barrel?

The barrel is threaded 1/2x28 TPI, which is the standard thread pitch for 9mm suppressors and muzzle devices. Any 1/2x28 can suppressor will fit.

What does 5R rifling do?

5R hybrid rifling uses lands positioned opposite grooves with reduced sharp angles. This design minimizes bullet jacket deformation, which improves velocity and makes the bore easier to clean between shooting sessions.

Is the Nitride finish better than stainless?

Nitride hardening locks the bore and extends barrel life while offering superior corrosion resistance compared to untreated stainless. It's harder and more durable for repeated use and cleaning.
