Mentioned my range bag in another thread today and thought I'd post what I use after several failed attempts with other products in the past. I use a G.P.S. Tactical Bag which can be seen on page 30 of the attached catalog. Very well made and as anyone who routinely goes to the range will know, the need for rigidity is important when you consider the weight of everything we bring with us. What do you folks use?
