Description

Faxon Duty Series Barrel for G43/43X 9mm Nitride

Faxon’s Duty Series pistol barrels for Glock® G43 are machined in-house from 4150 CMV steel. These barrels are then given a salt bath Nitride finish 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 Duty Series Barrel for Glock® G43/43X delivers rugged, reliable performance in a slimline drop-in upgrade. Built from stress-relieved 4150 CMV steel with a full salt bath nitride finish inside and out for maximum corrosion resistance and durability, this barrel is engineered for hard-use concealed carry, duty, or training applications where dependability is critical.
