This may have changed by now, but it is definitely worth checking on.
Meant to address the reply to your post. Good point!
FYI, I have the #57D, which is specifically made for the new 830 (and 820?), so some variation of the #57 can be used with 9mm machines.
Yup, that's the foot I have. The dual feed is wonderful for piecing.
