Faxon Firearms Duty Series Barrel Features The Faxon Firearms Duty Series barrel is machined from stress-relieved CMV steel for maximum durability and longevity under duty or carry use. A black nitride finish provides superior corrosion resistance lubricity and wear protection both inside and outside the bore.

The 1:10 twist rate is optimized for common 9mm defensive and training loads stabilizing a wide range of bullet weights. Built with tighter tolerances than the factory barrel this drop-in design offers improved lockup for the Glock 48 without requiring gunsmithing. The threaded muzzle is ready to accept suppressors compensators or a thread protector right out of the box. SAAMI-spec chambers ensure reliable feeding and complete compatibility with standard 9mm ammunition. For shooters building a slimline Glock 48 for concealed carry or duty use where performance and longevity matter most the Faxon Firearms Duty Series barrel is a proven upgrade available for sale at GrabAGun.
