I'm not doing any competitions yet(hope to head that way though) but I got tired of using the Walmart "plastic briefcase" pistol box so decided to build my own. If I ever start competing, then I'll modify one or build another to meet my needs. The larger has all the size in the world but I wanted something a little smaller to just go to the local range so I built the smaller box.
