Griffin ATM™ (Advanced Threaded Match) Barrels are billet machined from 416R chromium stainless steel to exacting tolerances for the ultimate in drop in match performance.  5 axis machining done in a single work holding positions all critical dimensions on the breech ensuring theoretically perfect geometrical relationship of barrel, slide and locking lug. Chambers are honed and polished to ensure an extremely smooth surface finish and optimal reliability with a wide range of ammunition from training to duty ammo.  Two years of research and testing provided the appropriate knowledge to machine the barrel dimensions for a perfect fitment; providing the best possible accuracy without sacrificing factory reliability.  Designed with concealed carry users in mind, this barrel gives you the utility of accessory and suppressor support while providing uncompromising reliability.   Don't lose confidence in your carry handgun by using sub par components.  

For a limited time this barrel comes with our patent pending Micro Carry Comp, a $64.95 value and an impressive performance add on for your favorite carry piece.  The Micro Carry Comp ( MC²) provides a low signature (resists printing while carrying concealed), fits a wide range of holsters without modification, and provides noticeable recoil reduction for faster more accurate follow up shots with enhanced overall control of the firearm. The Micro Carry Comp's miniature and lightweight package has near zero perceived effect on the handling and storage of the firearm.

    Barrel upgrade done right

    Published by Andrew D. on 2nd Aug 2019

    With my recent purchase of a glock 19 gen 5, I was on the hunt for an upgraded barrel with threading. I came across this fantastic deal from Griffin Armament with the barrel and a mini-comp I stead of your standard thread protector like most.
    Install was as easy and dropping it into the slide and installing the compensator, it's a perfect fit.
    Took it out to the range yesterday and did notice a decrease in time it took to recover for follow-up shots, would definitely recommend this barrel to anyone who is looking for an upgrade.

    Glock 19 thread barrel

    Published by Deion Clark on 11th Mar 2019

    More than happy with the barrel. Perfect tolerance. @7yds i put 7 rounds through the same hole less than 1 inch in diameter. (Unsupported) and @25yards besides a couple of fliers I put 8 shots in a fist sized area. Its more accurate than I am. Highly recommend. On top of all that the mini comp works well and looks awesome.
