Plus whn i had the grip off, i pulled up on the gesr box and moved it around a little bit. When the grip is off the selector switch should move freely. When its on it gets stuck. So take the grip off and pull on the gearbox and at the same time try moving the selector switch. If its tough then its a matter of wiggling the gearbox and pulling on it so it seats properly. I was just pulling on the gearbox and wiggling it theough the pistol grip and moving the selector switch when i noticed it just started working again. Let me know how it goes
Bang one, Bang em' all!
