Vinh's SW9 Frame, made by nguyenkvvn (aka Vinh), takes FMDA's SD9 frame and modifies it to support the older SW9 model parts. He did so because a lot of people mistakenly got those instead and they were close but not quite compatible.
Like the parent this also comes in a glock mag compatible variant.
