Faxon Firearms Glock 48 Barrel Features The Faxon Firearms Glock 48 Barrel is machined from stress-relieved 4150 CMV steel a process that reduces internal tension in the metal for more consistent performance and longevity under repeated firing. The 1:10 twist rate is matched to common 9mm bullet weights for reliable stabilization downrange while conventional rifling makes the barrel fully compatible with cast and coated lead bullets that some factory barrels are not rated to handle. For Glock 48 owners who shoot cast bullet reloads regularly this rifling compatibility opens up ammunition options a factory barrel may restrict. The black nitride finish enhances wear resistance and lubricity both inside and outside the barrel helping the part shed fouling more easily and resist corrosion over years of use. This drop-in barrel is designed for compatibility with factory Glock 48 slides meaning owners can perform the upgrade themselves without additional fitting or gunsmithing in most cases. Manufactured in the USA this barrel gives Glock 48 owners a domestically produced option backed by Faxon Firearms reputation for precision-machined parts. For Glock 48 owners looking for a durable American-made replacement barrel this Faxon Firearms barrel is available for sale at GrabAGun.
