WE Custom M&P 9 Slide issues
So I just bought a new WE Custom M&P 9. I like it, it's ergonomic and pretty. The problem is that i can shoot maybe 6-9 rounds off, and then it just blows all the gas out. It racks normally when you pull the mag out, but the mag in, or has issues. Does anybody know what this could be, or how to fix it? Attached picture to better explain.
