The Faxon Firearms Duty Series 9mm Barrel (brand part number 365A910NXNOQN) is a direct-fit replacement barrel for the SIG Sauer P365XL, machined from 4150 CMV steel for top-of-the-line durability and accuracy. Faxon finishes it in black nitride, a coating that adds an extra layer of wear protection while also improving the barrel’s lubricity for smoother cycling. Cut with a 1:10-inch twist rate to stabilize standard 9mm bullet weights, it’s built for a P365XL owner who wants to replace a worn factory barrel or step up barrel quality without changing anything else about the pistol.
