Hi Karate, try Robert Johnson, he's been real good about service, product and price. He's got the 15/16 rnd mags, I think their Walther mags for the hungerian army or police I belive. Their all metal and work great for $70 shipped. [email protected]
Email him and ask if he'd got anyin stock right now. I ordered 2more he's shipping right now.
Sometimes you can find them on Gunbroker or one of the auction site, but this is the best price I found.
