Hey HK45USP, Glad to see your still after the Ruger(factory) Hi Cap mags for the Mini's.As we know Ruger did make some 10,20 and 30 round mags for the Mini 14's. Even before the ban William B.(Bill) Ruger didn't want these Hi Cap released to the general public.To answer your question about Hi Cap Mini 30 mags. I have never seen one or can ever remember hearing about them.It's doubtful you'll find one and if you do be prepared to grab your billfold.I still have all my Factory Mini 14 mags.The prices for these is really getting outrageous. Especially considering what I paid for them way back.I wish now I would have bought all the shop had.I could be semi retired. The Ruger Folding Stocks,well that's another subject.Let's put it this way I would be retired if I would have played my cards right with the factory Mini folding stocks.LOL..
