So I was trying to adjust the damn door play on my browning hells canyon safe and while screwing in the screw the thing fell behind the door frame.  I would’ve thought the adjustment screw was captive but I guess not.  Cant locate it - pulled safe floor up and it wasnt under there either.  

Should I even waste my time looking for it (might be long gone in the interior of the door frame)?  Maybe a strong magnet to move it back upwards through the frame.  Or should I just see if browning will send me a new adjustment screw?

Try for a new adjustment screw.
