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.

Looks well made, fit was perfect. First outing had multiple issues with slide not locking back on empty mag and a couple of FTFs. After about 100 rounds didn’t have any more issues, other than slide lock back on a couple of mags only, but it could be the low powered CCI 115gm used combined with the comp. Definitely more accurate than OEM barrel. Overall a great buy for the price.
This barrel compared to the stock is far better. You can hear how much better the tolerance is compared to stock. The comp is also great. Sub guns can be very snappy and make for quick follow ups. This comp takes that snap away. Sure, it’s not massive but this thing doesn’t impact holsters, manual of arms, or spring settings yet takes some recoil out. The sig 365 feels more like a Glock 19 now. Highly recommend.
Haven't shot this barrel yet. But have one just like it on my G19 and it is awesome. The comp does make a difference.
Shipping was fast.looks nice..fits good..after 50 rounds shoots fine..love it!!
Great barrel I recommend
Fired my P365 with this barrel and it works great. I don't notice as much flip as I would with the stock barrel. It does not extend far out and the entire system is easy to install. I'm not the best shot but when trying this out it did appear to tighten up my groups. An excellent upgrade to your firearm. Recommended.
Great barrel and micro comp package for around same price as most aftermarket barrels. I shoot awesome groups with this installed, far superior to the regular 365 barrel. Also fits in the same holster!
Barrel was recomended by a friend. I don't regret it. It's great.
Have only made it to the range once since installing. Recoil is reduced especially in rapid fire. Accuracy is good. Recommend for anyone wanting a threaded barrel.
Griffin shipped my items really quick, I test fit them and the barrel lockup was great and didn't look like it had any issues. I went to the range and it was a pretty noticeable change from stock. Very happy with my purchase, I've told my friends to check these guys out for sure!
