dont suppose you could give some advise my s410 gets filled with a pump but i let it run low on pressure i dint relise how low it was and now its released all the air but got it filled today with a diver. the problem now is it is holding 190bar but wont fire its cocked and theres no click when you pull it back even after you pull the trigger and pull the bolt back again. i was wondering if it could be a jammed valve.
cheers
