Faxon Firearms 9mm Barrel for Glock 34 Gen 5

A replacement barrel for the Glock 34 Gen 5, chambered in 9mm like the factory tube it swaps out. Faxon machines its own barrels and holds tighter tolerances at the lockup and the hood, which is where most of the accuracy improvement on a Glock actually comes from rather than anything happening inside the bore.

The 34 is the long slide competition gun in the Glock lineup, so a barrel swap here is usually about shrinking groups for a match rather than fixing a problem. Installation is the same routine as a cleaning: field strip the pistol, drop the barrel into the slide with the factory recoil assembly, and reassemble. Function check it with the ammunition you plan to run before it goes to a match.
