I've got my name on one at Sports South and Lipsey's, which ever one comes first. I'm still waiting on 9mm carbines to become available. I need 4 of these for myself and my LE clients. I've got at least 1000 rounds of 10mm loaded with cast bullets that functioned in my Gen 3 M20, but won't function in my Gen 4 M20. They'll be just right for the GP-100. BTW, the Ruger SKU for the moon clips for the 10mm GP is 90661. None of the distributors have any in stock yet. That's one of the reasons I don't go to SHOT or the NRA Convention. I gave up looking at items you can't get. Bob!!
