Hello All i have been having this problem at least once during a match where my fully loaded 10 round mags seem to be locked in after a change, then when I fire the fire round, the mag falls out without picking up a fresh round and I am left with an empty gun. My mags still need some breaking in? They seem to be under a lot of tension. Never happens in practice only during matches, of course. I have loaded only 9 and this does not seem to happen. Suggestions? BTW, hi caps are a no no where I live.
