Well I have even been wondering about upgrading the mag perhaps. One of the issues I have been noticing with the mag is when I try to take it out is it can be kind of finiky and a pain to take out. So of course naturally I have been thinking "I wonder if there is a better quality mag/mag system that would make it easier and smoother?" but for now it works. Yes I too agree to have more than one mag. I have never had problems loosing them but I do know the value and convenience of having multiple mags.
