Thanks, I was getting confused by the pictures themselves!
I was under the impression that the first set of pictures were all the MPP 2.0 and the second set were all DV6.
So to summarise:
MPP 2.0 - ANH and ESB hilt, longer grip length is from ESB
DV6 - RTOJ hilt, shorter graflex based model
One thing that throws me off is that the MPP is called "2.0" like the graflex 2.0. But Korbanth wrote the DV6 is the "Graflex 2.0 design is modified". I assume this is the one that has the screw off lower section and the MPP is one whole unit that isnt removable? Am I wrong?
