yah but the tank that actually holds the gas is still metal therefor your heat capacity theory doesn't really work... a mag with a metal shell and metal tank wouldn't differ much from a plastic mag with metal tank. the reason the KJW has better cool-down rates is because since the mag is bigger the tank can be bigger too. plus thermolds don't fit in those open top pouches especially the double mag pouches because of the large ribs on the sides. anyone taken the mags apart yet? maybe a pmag/stanag conversion? dimensions look fairly similar....
scroll down about 3/5ths of the way to see comparison pics between pmag and thermold
