Limited production #07000DZ. Best info I have from forum people is that two batches of these numbering just over 200 pistols went out. Notice the round ports instead of Mag Na Port style trapezoid. Roll marks are nice, not cratered, though not deep. The sharp points at every corner of the slide are reduced. Inside of slide is very well done, maybe the Custom Shop reduced the tool marks?Ugly grips and sights that were coming with those guns.
