Description
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.

Just received this awesome barrel. The fit was truly drop in and I can find no flaws in the finish. I was considering getting a P365XL but this allows approximately the same barrel length in a more compact package. Overall I’m very satisfied and will update after range time.
Alexander Rodriguez –
Great quality! Makes P365 look great!
Kenneth Lumley –
Exceptional value, construction, design and functionality. Great job!

This is an easy upgrade for your P365. Drops right in, perfect fit and excellent quality. The micro comp is a nice touch and it looks great. I will say that with the micro comp installed, this barrel adds exactly 7/8″ to the length of the gun. I pocket carry and can still use the same holster. I would recommend this barrel to every P365 owner!

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!
James –
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.
Edwin Ribera –
Barrel was recomended by a friend. I don’t regret it. It’s great.
AD –
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!

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 I recommend

Shipping was fast.looks nice..fits good..after 50 rounds shoots fine..love it!!
Ed –
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.
Tim –
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.

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.
Stacey –
Looks great used one time like.
James –
Would absolutely recommend

Worked great first 50 rounds.
Gary –
Nice work, clean, good thread tolerances, and these are an unknown secret for P365 lovers.

I got this a little over a month ago. I have the P365, P365XL, P365X Macro, and P365XL on the X Macro grip Module. This barrel is match grade, it shoot awesome, accuracy is extremely good and the Comp beats the Sig X Macro comp.
Rudy D. –
Dropped right into my 365 and cycled completely fine all sorts of ammo from 115gr to 170gr with no issues.
Cycles fine without my suppressor.
BWS –
I was a bit skeptical at first, but I am extremely happy with my decision to go with this new barrel & its accompanying compensator. The amount of barrel climb is notacibly reduced and lows for much faster acquisition of the next target or setup for a follow up shot. If a friend or family member asked for recommendations for a setup like this, I would immediately recommend Griffin, no questions asked.
Lou –
Love my Sig P365 and I love tweaking it. I recently installed the DPM spring system which dramatically decreased flip.
A few days ago I received my new ATM barrel with micro comp and I must say it’s like a new gun.
My groups are as tight as I want them. Muzzle flip is practically eliminated. These products are game changers for micro pistols.
Zed –
This threaded barrel is perfect. I’ve had some aftermarket barrels with reliability issues in the past and was trying to find a good one for the P365. Works great unsuppressed and suppressed with the Griffin EZ LOK taper adapter.
Alex –
The definition of drop in. It ran just like factory even better with compensator. Very pleased, any chance you guys can make one for 17L gen 5 ? Thank you
