And old thread spoke of one made of courdura but I cannot seem to find it anywhere.depends on what you want to spend
Jason Coye makes one of the best also Edgewood bags
I like the way you think. The savings over a high-end holster would be better spent on components.A leather pliers belt holder from Home Depot with about 1" of the bottom cut out. It's tight at first but loosens up with use. I made the first cut and removal too little but the second one allowed the nose of the bolt to poke thru and it holds the bolt snugly but allows it to be pulled out without too much effort.

If interested, I have one of the original design. New, never used.
