It's a Rock Island Armory, 2 tone, 4", 1911, chambered in 9mm. I called the company, and was just told "we only make a full size 9mm" after talking for a little while, the tech said it could be one of there short batch guns, maybe 100, or so made. I found a bunch of people asking about them, but no real information, so i figured i would try here. I did find an add for CDDN that had it for sale, but the best i can find is they have been on back order for about 4 years, and RIA isn't planning on making any more. Thanks for any help you can give.
