Faxon Firearms Match 9mm Non-Threaded Flame Bbl For Sig Sauer P320Fs Black

The Faxon Firearms Match 9mm non-threaded barrel for Sig Sauer P320 Full Size is built for shooters who demand precision out of the box. Unlike stock barrels, this match-grade upgrade starts with 416-R stainless steel—the same material spec-ops armorers trust—and adds Faxon's signature flame fluting for weight savings without sacrificing rigidity. If you're running a P320 Full Size and want tighter groups at the range or in competition, a quality barrel swap is one of the highest-return upgrades you can make.

The 11-degree target crown matters more than most shooters realize. That precision-cut muzzle face helps consistency by cleanly supporting the bullet as it exits, which translates to tighter shot groups downrange. Faxon backs that crown with a salt bath nitride finish—a hardened coating that laughs off fouling, moisture, and wear far better than standard blued or parkerized finishes. The 1:10 twist rifling is tuned for the 9mm cartridge and handles the full spectrum of common factory and handload velocities.

This is the non-threaded version, so if you're planning a suppressor later, Faxon offers a threaded model. But if you want a clean, classic profile without the extra length, this barrel delivers the precision without the wait or the muzzle device.

Frequently Asked Questions

Will this barrel fit my Sig Sauer P320 Full Size?

Yes. This barrel is machined for the Sig Sauer P320 Full Size platform and is ready to drop in as a direct replacement for the factory barrel.

Can I use this barrel with a suppressor?

No. This is the non-threaded model. If you plan to run a suppressor, Faxon offers a threaded version of the same barrel.

What does the 11-degree target crown do?

The precision-cut crown supports the bullet cleanly as it exits the barrel, helping tighten shot grouping and improve consistency at the range or in competition.

Why flame fluting?

Flame fluting reduces barrel weight while keeping rigidity intact, making for better handling and slightly reduced recoil without sacrificing the precision this match-grade barrel delivers.
