So let's start again. Mags have always been the weak point on these guns and the C 9 seem to be the worst one. How many mags do you have? Are the all doing this? Can you post pics of fully loaded mags? I'm betting these are brand new mags and need to be broken in. everyone else will tell you the same thing I already said about the mags. Keep working the springs and let the mags sit fully loaded. The more you work them the better they'll get. If ytou're stil having problems after, say, 300 rounds, call Mom. She'll send you new mags for free
