There are quite a few 9mm carbines but many are out of production like the Ruger PC9 or the Marlin Camp9, they are featureless no rifles so there is no annoying bullet button and you can use standard capacity magazines if you had them before the ban went into effect. The ones in production are from AR's to Uzi's, Mac 10's, MP5's, UMP's and many more. Say other than the Hi Point in California and the Kel Tec if I lived in a free state most are expensive rifles around $1,000 or more. I think the Hi Point, Ruger PC9, and Marlin Camp 9, and the Masterpiece mac 10 clone are under $1,000 though. Im still kicking my self over not buying a Ruger PC9GR for around $700.
