I was stoked to see this but I wonder, why is the TM one a double-stack magazine that holds almost 30 and the WE is a single that holes like 15? It's the only thing holding me back from picking up the WE.
Single stack is better in airsoft, for the most part. Magazines are cheaper, 15 rounds is plenty enough (espcially considering the gas efficiency problems of WEs), and it is MUCH easier to find pouches for them. If you like the external design of the 4.3 Desert Warrior, go for it. WE 1911s are good.
It's a single-stack mag, because the desert warrior is a model of 1911, not 2011, like the TM Hi-Capas. Hence, it takes a standard single-stack 1911 mag.
