Yes we knew about the new frames, in fact that nifty black and white pic that barsto uses was one that I made (just for a little trivia). And yes the maglock mag well will not work with the new frame unless you rework it. Its easy to tell if you have the new frame or not Just look right behind the mag well at the half round area and match it up with the pic in barstos website. Or just look at the frame rails, the old stlye had one cross cut the new one has two cuts, one for a full sized weapon light and the smaller sized weapons light.
