[Hectic]

I dont think its the mags its the whole rig moving that is the issue

Does you rig have loops for a belt at the bottom? mine does and if i dont use a belt it flops around even with plastic mags, im not sayin the belt on your pants but another belt to use just as part of your rig my rig is just a cheap ass china rig shoulder straps and a mid section strap, but again if i dont use a belt on the bottom too it just flops around
