I have had my P99 9MM about 6 months (bought new)and have fired about 300 rounds through it. The mag release has always been difficult to get the mag to release ever since I have owned it. Well today when I inserted a mag it would not catch, the mag just falls out. I have tried all four factory mags and none will stay in.Looking down in the magazine well the mag lever works ok but there does not appear to be a lip on the release level to hold the mag in. It does not appear to be broken......Anyone have an idea, or problem like that? I have considered on driving the pin out of the trigger guard that holds it in and looking at it, but I am a little hesitant on doing it yet..
