FWIW, one of the LGS had the Ruger marked PMAGs 4-6 weeks or so ago. They were priced at about $24. I didn't buy any. Last week I noticed they had the same mags minus the Ruger label priced at $16, limit two. I picked up a pair.
Also, some AK mags I ordered from Cabela's back in January finally came in last week, just after I received a notice from Midway that the AK mags I had on back-order were available for shipping.
