I just bought some MP40 pouches for my Heavy Weapon Trooper from Epic Militaria. They are leather and seem to be well made and their service is great, would need some weathering for a TD though, you get both the pouches pictured for the price.
There's templates in Pandatroopers build thread here, it's the tutorial I'm using for my build.
I was gonna say "hey, nice butt" but then I thought about how that would sound................
