I have TM G17 and the fill valve seems to be defective. I did a search and none of the threads have the same problem. I cant get anything more than 1.5 shots out of a fill. Every time i try to fill the mag the gas just expels into the air instead of going in the mag(only enough to get 1.5 shots out no matter how long I hold it to fill it). I have tightened it and used silicone and let it sit and soak overnight but to no resolve. I am trying to find out where to get new fill valves but I cant find them for the TM Glock specific magazine. I have found TM 226 and 1911 mags but I am unsure if they are the same valves. Also If I dont need a new valve, what is the problem then?
