Polymer magazines do have their benefits and space age aesthetic, aluminum mags are a classic, and still work great. One of the benefits that aluminum has over polymer is that it does not swell in extremely high or low temperatures. The aluminum feed lips are also strong enough to withstand the pressure of a fully loaded magazine over long periods of time without bending or breaking.
