Lone Wolf 9mm threaded barrel

Range Hot-18

First, there is absolutely nothing wrong with factory Glock barrels, but there are a few reasons to swap out the  polygonal barrel from Glock for one with traditional rifling.

Range Hot-19

The first and maybe most important is while Glock advises against shooting lead bullets in their pistols, with a quick and inexpensive Lone Wolf barrel swap you can safely shoot lead bullets. Lead bullets are a whole lot cheaper than jacketed and if you cast your own there is a lot of money to be saved. With the cost of jacketed bullets being so much more than lead, the Lone Wolf barrel pays for itself pretty quick.

Glock chambers are generous in dimensions and while this promotes reliability it can cause a loss of accuracy and working the brass, shortening case life.  Lone Wolf barrels utilize a match grade chamber that has proven to aid in having the accuracy edge over the factory Glock barrel without sacrificing any reliability.

In addition to those reasons, Lone Wolf has plenty of options as far as barrels go, from length, threaded, ported, and conversion. I have tested Lone Wolf barrels before, you can read my review of the 10mm Auto barrel for the Glock 20 by following this link.  I have been using my Glock 17 as a test platform as well as a match pistol so I contacted Lone Wolf about a threaded match barrel to use and abuse.

There are a lot of options when it comes to aftermarket barrels for the Glock, but why I favor for the Lone Wolf barrel is while they are not very expensive they are match grade and drop right in. Many of the others while more expensive require professional fitting.

You can take the Lone Wolf barrel out of the box, drop it in your pistol, and go shooting. It is just that simple.

Lone Wolf Barrel Accuracy 9mm

Here is a side by side comparison of the factory Glock barrel as compared to the Lone Wolf in accuracy with nothing else changed in the pistol. This is from 25 yards shot from a rest

The two reloads were loaded with initial and close to maximum charges of IMR 700X

I have put together a couple of videos showing me use the barrel, and while a photo is worth a 1000 words, a video is worth a 1000 frames.

Local match I compete in, using the Lone Wolf barrel.

Testing The Streamlight TLR-1 HL and used the Lone Wolf barrel for the majority of the test.

Warming it up, still no failures.

I received this barrel from Lone Wolf the end of January and have run it on my Glock since I got it, except for the side by side accuracy test. My estimates are around 750 rounds through it, from my cast lead reloads, to full metal jacket reloads, to store bought FMJ and defensive rounds. Those rounds were shot at a series of action pistol matches, training, practice, and classes. I experienced zero failures and a noticeable improvement in accuracy.  All in all I would say the test was successful and this will be my go to set up going forth. Now if I could just get myself faster, more accurate, richer, better looking, younger, and so on.

I spent much of my youth involved with firearms and felt the call early on to the United States Marine Corps, following in my father's and his brother's footsteps. Just after high school I enlisted and felt most at home on the rifle range, where I qualified expert with several firearms and spent some time as a rifle coach to my fellow Marines. After being honorably discharged I continued teaching firearm safety, rifle and pistol marksmanship, and began teaching metallic cartridge reloading. In the late 1990s I became a life member to the National Rifle Association and worked with the Friends of the NRA. Around that time my father and I became involved with IDPA and competed together up until he passed away. I began reviewing firearms for publications in the mid 2000s and have been fortunate to make many friends in the industry. Continuing to improve my firearms skills and knowledge is a never ending journey in which we should all be committed. I am also credited as weapons master on a few independent films.

  1. […] The next area I addressed was accuracy. Though the factory Glock is plenty accurate as a defensive pistol I wanted to add any little advantage I could, so I ordered a Lone Wolf drop-in stainless steel match grade barrel. I opted for the threaded barrel. Though it does add a little length and weight to the end of the gun, I don’t know if that is enough to matter but I have another AAC silencer on the way for a review so that seemed like a good idea. The Lone Wolf barrel has traditional rifling, which will allow me to safely run lead bullets, cutting the cost down on practice quite a bit. The tighter chamber keeps the brass from expanding as much as the factory chamber. Not working the brass so much during resizing adds more reloads per case, again keeping the cost down. You can read how well accuracy was improved by following this link. […]

  2. Hunter, this is an awesome article brother! I had an idea for you, when I was shooting archery the target heads would always come loose. Maybe you can try a small dab of toothpaste in the threads, to keep your thread protector from coming loose. This helped with the repeated impact of target shooting, for me. If you’re ever in a jab you won’t need pliers to remove that cap.
