IIRC, it is heavier/thicker and more precisely manufactured and placed on the PB-207.

I can check on this later when I get home and can look at my PB-207 and a few other brands, including the DX, side by side.

One thing I don't like about the PB-207 is the roll-forward safety, but a pair of diagonal cutters will fix that in a second.
