OK, a few days ago, I went out to shoot at some targets, and after a while, my P90 stopped firing. The trigger just wouldn't go back enough. (No, it was not on safe) So after trying everything I could think of, my dad told me to let him see it. He started "Jerking" the trigger fast, and it started shooting again. but the problem is not completely gone. It still happens, even if it goes back to normal next time you pull the trigger. Does anyone know what I should do?
