I was about to respond to a thread, so I will respond here cuz I worked so hard on trying to post it.
I have one...I'm not sure who makes it but I put Blackhawk pouches on it and a Maxpedition "rolly polly" mag dump pouch on it.
I like it, worked great for a Tac Class that required we have it.
holds 10 30rounders some 1911 mag holders a hydration unit, the mag dump pouch and a flashlight with plenty of room to spare.
