Glock 19 Gen 3-5 – Zaffiri Precision Threaded Barrel – 9mm
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
These Zaffiri Precision threaded barrels are built for Glock 19 Gen 3-5 9mm pistols and use 1/2x28 muzzle threads for compatible compensators or suppressor mounts.
This is the threaded Glock 19 parent card because the fitment range is the same: Gen 3-5. Different finish, same job. Nice and clean.

Install Notes
Threaded barrel setups with compensators or suppressor mounts may change cycling behavior and can require recoil tuning.
Note: Recoil tuning depends on the full setup, including ammo pressure, compensator design, slide mass, optic weight, grip, lubrication, and break-in. Live-fire testing is mandatory.

- Verify your muzzle device uses 1/2x28 threads.
- Verify your holster clears the threaded muzzle or installed device.
