What magazine will fit in a CYMA cm 121?

As far as i know, you are going to have to find them seperatley. I've tryed to find some but they are pretty hard to find. You might be able to get it from like ehobbyasia or acmgear. You probably can find one if search it on google. In case ur wondering the other aep guns mags from cyma wont work in the desert eagle (cm121) and i dont think its compatible with mauri mags.

hope i hepled :)
