The first response before I had sent them off was they were not aware of any faults, that was when I posted this info on forums. I then spoke to one of our national A finalist's and he had the same fault but he uses mainly plastic savers so it wasn't a real issue but has sent it back with mine (I am led to believe)
They have been sent back to the uk distributor where I believe it's been sent to sanwa/Lrp Germany for investigation. As soon as I have the response I will forward the outcome. But it is always force in numbers ;-)
