I have discovered a problem with the PMAGs. A friend shoots carbine matches. He uses PMAGs for these matches and for duty carry. at a recent match he experienced a nasty type 3 stoppage that was traced to the magazine. The mag had been loaded via stripper clips with M-193 Ball. On the 2nd to the last round, FTF. As the picture shows the last round (first round into the mag, with its nose on the wrong side of the center rib. This caused the top round to be out of alignment enough to cause the FTF. When loading from a stripper clip the noses get pushed around at random angles. The first round in the mag obviously started on one side of the center rib but the follower pushed the body to the other side. The center rib prevented the round from correcting its self in the mag body. A GI mag does not have this center rib so the rounds will be corrected by the follower. The lesson is (IMHO) do not load PMAGs with stripper clips, Using a LULA or loading one round at a time should not cause this problem.
