I've been using this heavy duty tool bag made by CLC Custom Leathercraft for about 3 years now. After going through a couple range bags over the years, I decided to look for a quality large tool bag because they're designed for heavy loads and heavy duty use. I also needed something a little larger because of other family members sometimes making the trip to the range with me. In the center main compartment I can carry about a dozen boxes of ammo on the floor of the bag with room for 5 or 6 handguns in padded carry pouches. Also a few accessories like a couple of pair of hearing protectors and such. Other side compartments carry paper targets, ear plugs, eye protection, mags, a few gun tools and some basic lube and cleaning stuff. I like it alot because it can carry everything I need for a range trip and fully loaded, the shoulder strap is definitely a plus.
