I used one of these for the last 10 years as a range bag. I had a plastic 30 cal ammo can full of 9mm in the middle, with 5 common rectangle pistol sleeves along side it. There was still a little room for stuff like a staple gun in front of everything.  What really makes this perfect are the 2 generous side pouches. I kept 2 Howard Leight earmuffs in one side with my shot timer and gloves on the outer most sleeve,  then kept my eye protection in eye cases along with more gloves, wipes, a rag, gun oil, chamber flags target dots in the other. The front pouch I always used to throw picked up brass into.
The bag held up for years despite the weight (and it was always heavy! ).
Eventually the seam along the main compartment zipper was coming unraveled so I decided to retire it.
I decided to get a "real" name brand range bag and found myself having to leave a ton of stuff out.
Unsatisfied with that, I donated it to a friend and purchased the largest name brand range bag I could find. Even though it was larger than this bag,  I couldn't fit everything that I used to have in my NexPak in the new one. The pockets weren't too well thought out.
I still have that large bag, but I went in search for another NexPak bag like the one I was used to. I ended up finding them at the local gunshow which is where I bought my first one.
Amazon has them for about the same price so don't hesitate to pick one up. I hope these are built as well as my old one was. If so, I'm set for life,  because I bought several this time
