I picked up a camo tool bag at Tractor Supply. Many pockets, just the right size, many perfect mag-sized pockets, and it was close out priced at $13.
Liked it so much I went back and got the last one. One now carries my range gear, targets, spotting scope, etc., and the other carries my pistol rugs. Look at the tool bags, forget about the fancy-priced "range bags" that won't hold up as well.
