How does this 3.7inch barrel fit the standard p365 when they come standard with a 3.1inch barrel?

The threaded portion sticks out...

by Jason, Verified Owner, December 14, 2025
Does this take +P ammo? Manufacturer Answer

Yes, this barrel can fire +P ammunition however this will increase wear on the barrel and other components of the pistol. We do not recommend or warranty the use of +P+ or "Major" loaded ammunition in this barrel.

I have a threaded barrel for my G19 Gen5 from Faxon Firearms with a Herrington Arms compensator on it and it works beautifully. I am also a big fan of Faxon Firearms AR15 barrels; they are one of the best! So, it only made sense for me to get a thr...

Threaded barrel to replace OEM 3.1 barrel by Bill, Verified Owner, April 8, 2026
The threaded barrel that's supposed to fit as a replacement for the 3.1" barrel doesn't. It will run, but will beat itself up against the slide. The "chamber section" is oversized causing deformations on the barrel. Faxon sent me a replacement, bu...

Product Info for Faxon Firearms SIG Sauer P365 Threaded Barrel

Faxons 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.image
