have you tried loading a mag and leaving it in there for a couple hours, then pull them out and look at the paint? thats if you dont engage the pressure release - where you stick your finger in there and push them down until they click and are not under spring pressure.
This is what happens to mine after a couple hours of not using that pressure release. Its not a huge deal. if you engage it when you load the mags they are fine all day. and once you put the mag into the gun it will release the pressure. but if you leave them in the mag under pressure for a couple hours this will happen.
