Good to hear that bobneider. You will absolutely enjoy the heck out of the 9mm barrel with the .40 slide. It works just like it would if it were actual 9mm Shield. I have been testing mine for a few months (before we could even buy the barrels). I never had a problem with my originals, and now i havent had any problem with the barrel and mag ordered from Chris.......I'm glad to see they are still getting the barrels and mags out to everyone. My hats off to them for giving their customers what they ask for.
