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.

    Griffin ATM with Micro Carry Comp

    The thing that I love about this barrel and compensator is that it is low profile enough to conceal carry and the reduction in recoil that I get for follow up shots is amazing! Thank you Griffin Armament!

    I put about 300 rounds through the barrel and not only does it look amazing, but it also performs exactly how it looks... Perfect!!

    Great fit and finish, extremely good looking barrel. The idea of the micro comp is one of those ideas you wish you would have thought of. Shoots amazingly well.

    Love this product for my Glock 43. Gun shoots flatter at the range. Love the new tactical look of my gun. Form and functionality it’s a winner. And I don’t have to buy new custom holster for the the new threaded barrel with micro comp.
