Midway USA has the range bag I want, has the UpLula but not in stock, and doesn’t carry the magazine pouches I want.
Cheaper than Dirt has the UpLula and the Blade-Tech Revolution magazine holders, but both ship from different warehouses and incur double shipping.
Blade-Tech, of course, has the best prices on their magazine holders but don’t carry the other things I need so it’s still a third set of shipping to deal with.
I think I might just make mag holders out of cardboard toilet paper tubes, some staples and duct tape, then look for a diaper bag at a yard sale for the range bag instead.
