Treedawg, watch the Subguns boards. I see them pop up from time to time there. I used to see them on ebay too, but I haven't seen them lately. I have one, but only one 30 rd mag. Honestly I like the one for the AR15/M16 better. It is near perfect. When I first got mine for the Ruger it worked well, but lately it hasn't worked well (3 - 4 jams per mag). You may be better off with the Uzi conversion. I have one of those too, but my Uzi is still in transfer, so I can't comment on its function. It looks nice though. Good luck shopping.
