When I was making the sheaths for the company store they were 50/50 on the handles.Almost all of the handles on the BATAC's are standard. There are a few "magnum" handles out there, but even those are not the traditional Busse magnum scales with the palm swell, they are just a slightly thicker version.
If you can post a top-down pic we can tell for sure.
Odds are they are standard.
Swells out to 3/4 of an inch in front,middle,and rear,thinner areas are approximately 1/16ths thinner.
Sorru about the giant pic,stupid beta version Photobucket .Was looking at getting a Mashed Cat kydex.
