A long time ago, I traded with someone for their KWA Glock. I knew it had some issues, but I love the gun and its look. Unfortunately, it is not functioning at all. The issue I am having is when I try to shoot it, the slide only blows a little bit back and a lot of gas is released out the barrel. I have replace everything I can think of. I have replaced the loading nozzle, the valve inside the loading nozzle, the springs for the loading nozzle, and the hammer spring. I am an AEG tech not a GBB tech, so I could very well have missed something, which is why I am turning to you all. I'm out of ideas, so I will appreciate any suggestions for what I can do to get this thing working again. Thanks for reading!
