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. 

***DISCLAIMER: Coloration will vary barrel to barrel.***

    Axg Pro and pro cut slides

    Posted by Faxon Fan Boy on Dec 2nd 2022

    Bought this one locally, and for all of you wondering if it works with the full size pro slide… boy does it ever. This dropped into an Sig AXG pro so the beautiful finish could peak through those lightening cuts. Function 100% and to my surprise there was actually a noticeable increase in accuracy. Thought that part was going to be negligible. Runs great with a rugged obsidian suppressor, if they ever get the comp back in stock I will snag one and report on how that goes.

    The Chameleon is a literal work of functional art. Fits perfect. Amazing tolerances and the coloring look awesome against the black Sig Sauer p320.
