Faxon P365 Straight Fluted Barrel, Threaded, Nitride

(5 reviews)
Current Stock:

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.

    Supirior quality, Accurate

    Posted by Mark S Webb on Apr 2nd 2022

    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.

    Perfect addition and well worth the money. Better feel and accuracy. Added a Micro compensator on the thread and really helped with muzzle rise. Would buy again.
