Sam, I have this barrel works great in both G27s I have. Most people will say you need 9 mm magazines so I use them. I have plenty, but still use 40 S&W magazines. Wanted to know if they would work with 9 mm rounds. They do.The 40 S&W magazines will work with 9 mm rounds in the G27 with the conversion barrel. Might as well buy some 9 mm magazines if you want to shoot this conversion barrel a lot.

you will need the barrel and a recoil spring the mags will work
