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.

    Excellent and 350+ rounds field tested

    Published by JB@WV on 25th Apr 2024

    Precise fitment and excellent quality. Shot true every time during a 350+ round training day. Preferred 115gr to 124gr. *disclaimer* I'm using a heavier Harrington 365-2P comp (top ports only) until Griffin finishes designing a more sizeable alternative to the micro carry-comp. (Please?) The micro comp is great, too, for what it is. I just wanted an aggressive top port comp. The Griffin barrel delivers in every regard.

    P365XL Threaded barrel w/Micro Carry Comp

    Published by Brian L Lunt on 23rd Nov 2023

    The workmanship and finish is suburb and it dropped into the gun without any problem. I have not taken it to the range yet, but every prior item purchased has met my needs completely. Any question I have had was answered quickly and the representative was always pleasant and knowledgeable about their products. Customer Service is important to me and if two companies sell a comparable product, their CS reviews are always the determining factor for me. I used to be a Statistical Process Control Coordinator at an auto parts company. I learned CS was as important, if not more so, as the quality of the product.

    Good micro comp

    Published by S J on 1st Jun 2023

    I got this for my EDC. Though personally I wouldn't suggest it for your EDC since the barrel sticks out of my holster. If you have a holster that can cover the protruding comp, then "comfort" will not be an issue when sitting down. If you can put up with that/ don't mind it, then this is a very nice upgrade. Makes range day a little more fun!

    365xl threaded barrel and micro comp

    Published by Adam on 16th May 2023

    Significantly reduced felt recoil due to increased barrel length and the comp. I'm not sure how useful the comp is because of the design and have noticed signifcantly increased carbon buildup on my wml from the comp. I will test it out with only a thread protector in the future. Enjoy the product so far. Just be careful to buy a longer holster or watch out for a hot muzzle when you are stringing shots together.

    Huge difference.

    Published by Tristan on 9th May 2023

    I’ve put 500 rounds through my new Griffin Armament barrel and micro comp. I could not believe how noticeable of a difference the micro comp made with recoil. I EDC with this now for a bout a week and don’t notice the comp. Great product.

    Sig 365XL Barrel

    Published by Antonio on 20th Oct 2022

    Finally got one; don’t wait, get it as soon as you see it available. Tight group at 10 yards and no issues with or without suppressor. My only complaint is that I was having so much fun punching holes that I ran out of ammo before I had a chance to test it farther than 10yards
