Glock 19/19X/45 Gen 5/6 – Threaded Barrel – 9mm 1/2x28 – Includes Micro Carry Comp
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
This Griffin Armament ATM barrel is a threaded drop-in match barrel for Glock 19 Gen 5/6-pattern 9mm pistols and related full-size grip compact-slide variants including the Glock 19X and Glock 45. It is machined from 416R stainless steel, finished in black nitride, and ships with Griffin’s Micro Carry Comp already part of the package.
This is the kind of setup that actually earns its keep. It gives the pistol suppressor-ready threads, a compact compensator option, and better out-of-box value than barrels that make the buyer buy the useful parts one at a time.
Fitment
- Fits Glock 19 Gen 5 and Gen 6
- Fits Glock 19X and Glock 45 in 9mm as stated by Griffin Armament
- Thread pitch: 1/2x28
Does NOT fit
- Do not assume fit with earlier Glock 19 generations
- Do not assume fit with non-9mm variants
What it does
This replaces the factory barrel with a threaded 9mm barrel that supports suppressor or muzzle accessory use. The included Micro Carry Comp also gives the pistol a compact recoil-control option with minimal added bulk compared to larger comps.
Why it’s worth it
For carry-size Glock builds, there is always a fine line between useful and ridiculous. This setup stays on the useful side. The fitment list is good, the included comp has real value, and the price still lands in a defendable retail lane for a serious upgrade.

Install notes
Griffin positions this as a drop-in barrel, but function checks, ammo testing, and point-of-impact confirmation still matter. Especially on compensated or suppressed pistols, trust live-fire results more than internet chest-thumping.
Verify before you buy
Verify your exact pistol model, generation, caliber, and intended muzzle accessory setup before purchase. If your gun has aftermarket slide or recoil-system changes, confirm reliable function after installation.
