No, Ruger does not produce any 10 round mags. They did in the past (I have 2 of them) but they haven't made any in years. I'm told they were made for export only and this was way before the hi-cap mag ban. These have metal floorplates just like the 20 rounders instead of the plastic flooplates like the 5 rounders. There is no reason that Ruger couldn't start making them again except that they choose not too. You would think that since Bill Sr. retired, Ruger would loosen up. Maybe after he's passed....
