Most Helpful Positive Review Awesome barrel
Bought this for my Glock 22 Gen 3. I already have the Alpha Wolf 9mm conversion barrel, so I knew what to expect. The fit and finish is fantastic. Oiled it up a bit and ran a bore snake through it before shooting it for the first time just for good measure. I ran 150 rounds of Speer lawman .357 sig at the range. Shoots like a dream. I wish I didn’t have to spend $90 on ammo haha.

Great conversion or replacement barrel.

by CDKJudoka, Verified Owner from PA, United States Written on October 24, 2025
I bought this as a conversion barrel for my Gen4 G22 since the G31 is getting next to impossible to find. The AlphaWolf dropped right in and ran like a top. No failure to feed or eject with WWB 125gr or Federal HST 125gr. I recommend this for anyone with a Gen3 or 4 G22 to expand what you can shoot out of it.

Lonewolf .357 SIg barrel

by dgr, from NM, United States Written on October 17, 2025
Other than having to spend over an hour cleaning the bore, pretty happy with this. Apparently, this was a return with quite a few rounds run through it. I looked down the bore and could not believe what I was seeing. No witness marks on the barrel, but filthy none the less. Thanks optics planet for the extra work!!

extra barrel

by libras322, Verified Owner from FL, United States Written on November 29, 2023
Haven't had a chance to function test this barrel yet but I have no doubt that it will be as good as any other i have gotten and used. I have a 9mm none threaded 9mm threaded 9mm ported 40 s&w a 45acp and 10mm all work fine with good accuracy. The 9mm none threaded has thousands of rounds through it and has held up well. I just bought this one just to have in my g22 bag for just incase
