I've seen the in pictures, none in person. I don't think they've been released yet. They look nice. My 47D's have worked fine for me, so maybe with a new model, the price of the 47D's will come down some.
I have to say though, that while I have been happy with my Wilson mags, I recently picked up some CMC 8 rounders to give them a try. I have been equally as happy with them, and they are almost half as much. So I can get twice as many!
