Faxon Match Series Straight Fluted Threaded Barrel for SIG® P365 9mm Nitride
Faxon’s Match Series pistol barrels for SIG® P365 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 Straight Fluted Threaded Barrel for SIG® P365 combines match-grade accuracy, lightweight design, and suppressor-ready versatility in an ultra-compact drop-in upgrade. Featuring a clean straight fluted profile for reduced weight and improved heat dissipation, a threaded muzzle for compensators or suppressors, and a durable salt bath nitride finish inside and out, this barrel is ideal for concealed carry, competition, or custom P365 builds where precision and performance are paramount.

Supirior quality, Accurate
I Purchased the Faxon Barrel many for the quality workmanship, better than O.E. tolerance. After sight in hit 100 Yards steel first shot, added the Armory Craft . The added weight of the Compensator increases stability during precision or rapid live-fire using a Shield RMSc Red-Dot. Also using a Strike Slide, chosen for ease of rack, athetics, quality. As with any new gun or part, clean thoroughly removing all manufacturing/Machining oils and particulates. Then as per your normal cleaning procedures. Highly recommended upgrade for your P365. You won't be disappointed.

I added I micro compensator to this barrel for my P365X and it substantially reduced the snappy recoil of the pistol.
