Hi Bryan, no sir, this only fits Gen 1-4 pistols.
Stay safe & have a great day!

sorry it does not work in a gen 5 see *****"Flame" Match Barrels for Glock® 34 from Faxon Firearms have innovative, variable-depth fluted "flames" that give your pistol a unique appearance, and more importantly give extra rigidity and help dissipate heat. This results in a barrel that’s highly resistant to accuracy drift due to heat warpage - just what you’re looking for in a hard-running action competition pistol. Faxon Flame Match Barrels for Glock® 34 are meticulously machined from triple stress-relieved 416R stainless steel to tighter tolerances than factory barrels to ensure consistent, secure lockup and, consequently, tighter groups. Muzzles have a meticulously cut 11° target crown to ensure the bullet departs on a true trajectory.
