I need help! Adjusting the valve is pain
I have some serious problems getting the performance I used to, out of my mags. I cannot get them to work equally, I’ve taken them apart, lubed them etc. out of one of them I once got like 90rnds, right now my most efficient is 70rnd. And the onther one is around 50-60 and the last is roughly 25-30 rnds. I am at the point, where I just want to give up. I do not understand why it won’t work. And another question is, does it make a difference if I test the capacity with bbs or dry fire?
The gun was freshly serviced and cycles really smooth with no close to no friction between the slide.
