I just got a FDE Gen 3 Glock 22 and I bought a Lone Wolf stainless 9mm conversion barrel for it. They say you don't need to do any work to your Glock 22, just drop in the 9mm conversion barrel (use 9mm mags of course) and the gun is good to go as a 9mm. My only concern is the extractor on the Glock 9mm models are different than the .40/.357 Glocks. Does the straight extractor in the Glock 22 work ok when using 9mm with a 9mm conversion barrel? Anyone have any experience with this? Thanks. I would assume it would be reliable for range use only.
