Ok guys after many attempts at trying to obtain a grimlock here in Melbourne i managed to source one then it had a busted arm on opening so was exchanged and the 2nd version happens to have a problem where the pin in the left articulating hand hasn't been put in properly resulting in an inability for grimlock to hold weapons in this hand, ive seen other people return theirs for refunds replacements over this.. but now that stock is pretty much non existant and i really wanna keep grimlock just wondering if anyone is aware of how to fix this.. the pin doesnt simply push out like rodimus (or im doing it wrong)

The top: pin sticking through


The bottom: open whole which should be at top
