Most Helpful Positive Review Just what I needed
Put this four inch barrel on a Glock 26. (Instead of the 3.4 that it comes with) Fit and finish are excellent. Could not be happier. Drop in and go. For me, it makes this tiny pistol more manageable. Thanks for making a quality American product at a very reasonable price. - JD
Most Helpful Negative Review 9mm Barrel
When I first got it I couldn’t pull the slide back at all it it was too hard and it would get stuck but I sanded a couple of places on the barrel and slowly got got a bit better and would get stuck but I shaved it off enough so the slide and slide back

Excellent value

by SS Mark, Verified Owner from IL, United States Written on January 8, 2025
I received the barrell last week. I immediately checked it for visual defects, there were none. The surface looked good there were no tooling marks the chamber ramp was polished and the rifling looked good. I checked the cartridge support with a 9mm round I had and it was very good. A tight and very supportive fit. I then cleaned the barrel and put it in my new G19 build. I took it to the range and at 10 yards I was able to shoot tight groups, literally bullet holes touching each other in a short string pattern at quick fire cadence. The barrel functioned well in my build and I am very happy with it.

Worth every penny.

by Glock gets going and never stops., from MI, United States Written on November 12, 2023
I own 6 Glocks, 2 G19 gen 5, 1 G43X, 1 G17 gen 3 and 2 G 22 gen 3, all with lone wolf barrels. Just fyi, my g22 have lone wolf drop down barrels from 40 cal to 9 mil and have never had a feed problem So I’m unsure what issues others are having but as far as I can tell, these are great barrels for the money.

Waste of money

by Asian Patriot, Verified Owner from WA, United States Written on July 6, 2021

Pros:
  • Non
Cons:
  • Over Priced
  • not good quality
Best Used for:
  • Put on the wall
Would recommend: No

Great barrel

by T-M, Verified Owner from TX, United States Written on April 21, 2021
Not sure what the issue is with the other reviews, but I own two of these barrels and both fit perfectly and shoot great with zero failures. I have one Glock OEM barrel that would have an occasional FTF, but never have any with this one in the same frame. Also looks good.
Pros:
  • Good price and availability
  • works great ,easy install
Cons:
  • None
Would recommend: Yes
