Yeah, I need to do something about those cases.
It is kinda ugly but I am just intrigued, plus I want to figure out how it works. The slide is heavy, I am almost sure that is the key to it's function.
An example: the Witness it a medium weight, the XDM is about 2oz more. The G20 is a little heavier then that. So that the JPX being heavier should absorb ever more punishment.
