FAXON MATCH SERIES FLAME FLUTED® THREADED BARREL FOR P320 FULL SIZE 9MM
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.

Awesome barrel!
This an awesome barrel, really improved my P320 FS, greater accuracy, tigher lock-up and it great appearance enchancement! Nice that FAXON included an O-ring for their thread sleeve protector ( Sig doesn't) to prevent it from loosening. The barrel is slightly longer than Sig's OEM threaded barrel which in my opinion is a good thing! With this barrel has made my P320 a 1"MOA at 25yds and can just about match my Sig P210 Target for accuracy! AWESOME! Thanks, FAXON

Excellent Barrel.
I slapped one of the bad boys in a certain chassis made by a certain company in Utah, and it's sweet. I shoots lights out, period. No issues with reliability and I have been able to make consistent shots at 50 years. A worthy improvement to anyone with a Full Sized P320.

Having purchased Faxon AR barrels in the past, and I swear by them. This was the first Faxon pistol barrel I purchased, and will not be my last. Quality, Accuracy, Looks are make my P320 sing like Etta James!

Accurate
Nice little barrel pretty accurate. Only reason I’m giving a 4 is because it didn’t mention anything about removing the chambered round indicator in the description.

Awesome barrel
Shipping was extremely fast. Quality is excellent. Adds 1 “ to original barrel lengths. Longer barrel means more velocity as well as accuracy. Extremely pleased with this product. It looks great with the fluted flames as well.

Great barrel. I am using in a tactical competition lights out moving target only visible for 1.5 seconds several times during 2 min duration requiring 3 shots.
