I received an email from them today:

Here's a pancake style holster of theirs that I have for my MK9.
Slots are for 1.5" and under width belts.
Their website says they "use 7 to 8 oz. premium Hermann Oak vegetable tanned cowhide leather, wet molded to fit the gun."
The fit is very good.
The leather is about as thick as that used on this Aker thumb snap holster that my CW9 rides in:
However, it's doesn't feel as thick (but, it's real close) as the leather used in the Mitch Rosen holster I have for my CW45 (bottom):
