UPDATE
I just spoke with both Classic Arms and J&G Sales. The rep from Classic Arms said they were expecting them in the middle of January, whereas J&G said that they're just waiting on their distributor and it could be a week or it could be a year.
Even though J&G's answer was more vague, it is probably more accurate. J&G seems to run a way tighter business than Classic Arms does, but that might just be my impression.
