I agree with you. The vertical hip pockets look to be part of the pants, not made of leather. the holster pads on the other hand, i'm not sure if they're attached to the belt, the pants or maybe even both.
This was my plan. Some sort of strap that had a hook attached that the front hand guard could rest in.

Excuse my 2 minute drawing from illustrator. But after seeing these pics, rather than just a strip, a full holster pad with an hook integrated in might be more accurate. but still, should it attach to the belt, or the pants or both??
