Just curious to know if anyone owns a .40 to 9mm conversion barrel? If so, how's the reliability? Do you need to use 9mm maggs? Any other mods necessary in order to accomplish this conversion? Thank you

I also have one and I had to get a 9mm recoil spring in order for it to cycle properly. But it does feed with 40 or 9mm magazines. It's much cheaper to just buy the recoil spring and swap it on your existing assembly, but it is a bit of a pain to do.
