Hi and thanks for the reply. It happened to two out of three mags that I have . It started happening on the last range visit. Put three hundred rounds through it. Started on two mags roughly after first one hundred rounds. stripped the mags and can't find any defects.Argyle_Armoring said:I have not had that problem nor heard about that problem. Try replicating the problem and make not if it is only happening with one magazine or all magazines.
