The magazine that caused me so much grief was a wilson combat 10 round. the others were Chip McCormick which were 10 rounders also.
I have since run 125 rounds through the wilson magazine and had no issues on the fourth or first round? Go figure
Today everyone fights! No one quits. If you run I will shoot you myself - 1st Lt MOB inf Malson this goes for you to. No more leaving the firefight to go find something.
