Double Diamond Threaded Barrel

Fits great for my Glock 34 gen 4 looks great!

Outstanding service great barrel. Due to tight tolerance I had to install the slide with magazine well pointing to the ceiling (upside down from normal) I had to call customer service to figure this out thanks John N. Only fired about 25 rounds thru new barrel but I am very impressed with how the gun feeds and much better accuracy than OE. Polished ramp is amazing!!!

Works great noticable difference in accuracy along with my other mods in my gen 3 g22. Good buy.

Fit perfectly and works great in my G19 gen 3

I build competition level firearms for 3Gun, USPSA, IDPA, and IPSC. I'm not easily impressed and don't usually take the time to write a review for purchased components.

I expect 2" groups out of most pistols. And today, that all changed! I took a new 3Gun pistol to the range for its first test firing. One of the used components for this Glock 34 was a Double Diamond threaded stainless steel barrel.

I walked the Vortex Venom shots into a bullseye setting and then fired 3 rounds on a fresh target and checked it out. I then fired 7 more shots and ended up with a 10 round 1" group! For me, that's the very best group I've ever had with any pistol!

All future builds will have this barrel!!!

With the stock 10mm barrel I had a 5" pattern at 20 yards. I now have a 3-4" pattern. I am waiting on my stamp for a can and I have the slide in for weight reduction cuts and a RMR cut. This will be a hard hitting race gun.
