The barrel on a 30 S has a different outside diameter than the standard 30 . Not sure about the SF but I believe it has the same barrel as a standard 30. Some people get the S mixed up with the SF . Make sure that he is not doing that. The 30 S has the slimmer slide and different barrel and the slide is marked 30 S and uses pretty much the same barrel and slide as the single stack 36.
