now listen to this:
I was getting a low output with a Hi-capa magazine on which a replaced the lip.
Knowing the gun works well, I got fed up with the mag and decided to 'up' the output by unscrewing the output valve as much as I could before leakage.
I got one turn, that must put the valve a fraction of a millimeter higher, and it did the job: the mag now works.
So now I'm going to try that whenever I get not enough output - probably adding a little teflon tape on the beginning of the threading, which will allow the valve to sit a little higher, in order to get more 'hit' from the hammer.
edit: just tried on one G26 mag, didn't work, doing more tests now
