I am interested because it looks like a steel barrel and steel slide. I was considering the conversion kit for the CZ Shadow 2 until I saw Glocks advert. I don't like the aluminium slides on a lot of the .22 pistols, they seem to wear too quickly, I currently have a S&W compact and used to own a Sig 938-22. Hopefully the G44 will complement my S&W 617 and Ruger 22-45 for longevity.
