Caveat number one: these are belt slide pouches...but....
I have a leather mag/light pouch from HBE Leather. A really good equivalent is from Mitch Rosen, and I believe (but I could be wrong), the first of these combo pouches, the SOS. Dillon Precision sells them for $55:

Our resident custom leathersmiths can certainly make excellent equivalent pouches as well.
