$126.00
Faxon Match Series Flame Fluted® Barrel for SIG® P320 Full Size 9mm Nitride
Faxon’s Match Series pistol barrels for SIG® P320 are machined in-house from stress-relieved 416-R stainless steel. These barrels are then given a black Nitride or PVD coating to increase lubricity, barrel life, and resistance to surface wear. All barrels are conventionally rifled to allow a wider range of ammunition to be used, including cast lead. The barrels drop into factory-spec slides with no gunsmithing required. Better-than-factory tolerances ensure a consistent, tighter lockup than OEM.
The Faxon Match Series Flame Fluted® Barrel for SIG® P320 Full Size combines match-grade accuracy, patented lightweight design, and exceptional performance in a drop-in upgrade. Featuring the signature Flame Fluted® profile for reduced weight and superior heat dissipation, along with a durable salt bath nitride finish inside and out, this non-threaded barrel is ideal for competition, duty, training, or custom full-size P320 builds where precision and reliability matter most.

Full size Sig 320 barrel.
Fit and finish is far superior to factory. I was having issues with the accuracy of my factory barrel (it just wasn't grouping as well as I thought it should). Caught the 4th of July sale and purchased this barrel and problem solved. Fit and functioned perfectly and shoots like a lazer! Buy with confidence.

Does not fit Sig 320 M17
I purchased for my Sig 320 M17. I did not realize the M17 version was different. There is a slot in the chamber end of the barrel for the loaded indicator that does not exist in the Faxon barrels.

Faxon Sig P320 Fullsize Flame Fluted barrel, non-threaded
I built a full sized Sig P320 pistol using a Sig Sauer FCU as the basis. The Faxon barrel fit perfectly with no modifications and its flame fluting looks great as the slide of the pistol has side cuts.
