Here is a rig that Mark Whyte of Whyte Leatherworks put together for my son, who wanted a rig for backpacking.
We were working with a few problems here. First, Mark had to lay hands on a new model Bearcat to make a pattern for the holster. He found a friend at a shoot who accomodated him.
Next was getting a cross draw holster, cartridge pouch, and Buck Woodsman knife all in a comfortable and handy position when the wearer has a 29" waist.
The gun leather and knife sheath match perfectly, and the whole rig with gun, knife, and ammo in place weighs three pounds, the same as an unloaded Super Blackhawk
The only thing my son has left to do is to get a lanyard ring put on the Bearcat.
I was very pleased how the whole project was brought to fruition by Mark Whyte of Whyte Leather Works.

Mark might be offering this as a standard item.
