I also recently snagged a couple of the Kingman Training Utility Belts (damn I wish they had a Bat-arang attachment). They won't hold a full 10-round tube. but if you cut the tube down to 7-round length, they're supposed to fit (I haven't cut any tubes yet). I mainly bought them because they were fairly cheap and I wanted something with less capacity than the Doc Nickel pack for walk-on play. I'm hoping the flaps will fit tightly enough to not need caps on the tubes.
