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.

I was looking at purchasing a much more expensive barrel when I ran across the Griffin Armamnet barrel.
After receiving it I’ve ran multiple boxes of ammo through it with no problems. It’s just a accurate as my coworkers more expensive brands but with noticeable less recoil. The Mini Comp is where it’s at!!!!

Love this barrel Awesome product thanks Griffin

I wanted a TB for my Gen 5 G17 FS MOS. I have purchased many barrels for various weapons, and this is the most well fabricated barrel I have ever purchased. Accuracy, craftsmanship, aesthetics – are all there. Furthermore, the price for the barrel alone is excellent, not to mention the free MicroComp. What a deal. I will be buying more for my other pistols. Veteran owned and made in USA as well. Congrats on a great product and many thanks. PS, I bought my barrel and this review was freely given.

Incredible… Well made, beautiful tooling, great service. This has brought my Glock 17 Gen 5 into a new world, I am shooting tighter groups at 35′, mostly bulls eyes at 5 yards .. Thanks for the great product and good service.
Herschel Williams –
Beautiful and functional, great price..Shoots very accurate..Just as good if not better that the factory barrel.
Ken Bradwell –
Very nice barrel with tight lock up. The serrations also match the gun nicely.

Griffin hit a homer with this barrel. It locks up way tighter and the finish is excellent. I would put this barrel up against any other more expensive manufacturers. The micro comp is a pleasant bonus and looks fantastic on my Glock. This barrel makes my Glock a tack driver from 25-50 yards paired with rds. The milling on the barrel looks awesome too. Wouldn’t spend my money anywhere else!!

The barrel took longer to get to me but the Quality seem pretty good

I was originally going to buy an OEM threaded barrel but during my search I ran across Griffin Armament. A little more expensive with the comp but what the hell. Got good reviews and I’m supporting a fellow Marine brother.
I’ll have to admit, I was very skeptical of this compensator having tried others on competitive pistols over the years.
The Machine work and finish on the barrel and compensator is spectacular.
The barrel fit exactly like my OEM GEN5 barrel fit. As far as accuracy goes they seemed about the same. But I’m not a bull’s-eye shooter either.
I was way impressed with that little compensator! Ran great with factory loads and ejection still was strong. And there was definitely a noticeable difference in muzzle rise and felt recoil. Not life-changing, but definitely noticeable.
It’s even got me thinking about breaking my rule of non-modifying my carry gun. The Glock 43X.
Awesome product!

After just 100+ Rounds I can feel the noticeable difference with this compensator even for its size it’s very good and as for the barrel well it’s definitely beautiful as well as durable… you see I mainly upgrade my Glock so that way I can be more affective at protecting my loved ones so I honestly trust this quality. So my only regret is that I wish I was able to get a silencer for my Glock from them but sadly it’s out of my budget. So I highly and wholeheartedly recommend them to anyone.

Recently purchased the Glock 17 Gen 5 threaded barrel with micro mini comp. Fit my Glock perfectly and looks awesome. Purchased it specifically for a new suppressor, can’t wait to use it. Gonna fire it this week to see if the comp helps me shoot tighter groups.

Arrived on time, well packaged, 30 second drop-in, with a tight secure fit. There was nothing wrong with the accuracy of the OEM barrel, Griffin ATM is threaded and produces like groups @ 25 yds. Unable to test with suppressor at this time…

Very prompt shipping. Quality product with excellent workmanship. Look forward to its service in my weapon
Tristan Wiley –
I haven’t shot it yet, but so far I like it. I chose this barrel because A: most bang for my buck. Other barrels are similarly priced but don’t even come with a thread protector, much less a comp; and B: needed a gen 5 barrel for a 19L build and this one was in stock.
Jose A Ortiz –
Love my new Barrel and Comp. It’s a perfect fit and the black color matches perfectly with my firearm. Thanks
Caleb Joseph –
Really good quality I love how it shoots
James M. –
The fit and finnish is amazing! The cuts on the barrel match my slide. Highly recommended!
H. –
Fit just fine.
Much like my Sig P320 Griffin ATM barrel it’s worked/fit flawlessly.
I do suggest, which is something I didn’t do with my P320 version. Clean it after use. The build up that accumulates on the compensator is insane.

Few months and a few hundred rounds through this in my Glock 47, suppressed and unsuppressed, no hiccups, great consistent accuracy, it’s working out pretty great!
