First off everyone needs to take a breath and try not to take disagreements personally. Before this thread gets shut down I will put my 2 cents in one more time. I agree with 355sigfan to some degree. There are many magazines that have been designed for over 30 rounds that have malfunctioned consistently when loaded to over 30 rounds, and there can be a problem with extremely high capacity magazines due to spring tension. The Sten gun magazines and I believe the MP40 magazines had this problem, not to mention the many aftermarket AR-15 magazines. I also agree with Chris Rhines, there have been numerous designs that have succeeded in creating a magazine that holds over 30 rounds. The Steyr Hbar, RPK, HK33, amongst some that have already been mentioned can reliably feed while holding more than 30 rounds. The question that needs to be asked then is what do these magazines do to mitigate feeding problems that others do not, and has DPMS done this in their new magazines?
